Smart rings promise something appealing: health and activity information without another screen on your wrist. They can collect data in the background, remain less visually intrusive than many smartwatches, and may be easier for some people to wear overnight.

That does not automatically make them worth buying.

A smart ring is worth it when its present-day capabilities solve a problem you genuinely have and when you will use the resulting information after the novelty wears off. It is not worth it merely because it measures more metrics, generates attractive charts, or looks like the next major wearable trend.

The most useful question is therefore not, “How many features does this ring have?” It is:

What must be true for this device to remain useful after the first month?

For most buyers, the answer depends on five things:

1. The ring must be comfortable enough to wear consistently.

2. It must provide information that is understandable and relevant.

3. It should solve a problem that an existing phone, watch, or fitness tracker does not already solve.

4. Its total cost—including any subscription—must feel reasonable.

5. The data should support better awareness or a practical decision rather than create confusion or score anxiety.

This guide uses those criteria to help you decide whether a smart ring fits your routine.

Quick Answer: Are Smart Rings Worth It?

A smart ring may be worth considering when you:

• want passive, screen-free wellness tracking;

• dislike sleeping in a smartwatch;

• frequently remove a watch for work, charging, or personal preference;

• care more about sleep, resting trends, and general activity than live workout feedback;

• prefer a ring-like design in professional or formal settings;

• understand that sleep stages, calorie estimates, recovery scores, and similar outputs are algorithmic estimates;

• will review and use the information consistently;

• accept the full cost of hardware, accessories, and any required membership.

A smart ring is less likely to be worth it when you:

• already wear a smartwatch comfortably day and night;

• mainly need built-in GPS, live pace, heart-rate zones, maps, notifications, or music control;

• expect medical diagnosis or clinical-grade monitoring;

• rarely check health apps or change decisions based on wearable data;

• become anxious when daily scores fluctuate;

• would be stretching your budget to pay for the ring or its subscription;

• are buying primarily because of promised future features.

The practical conclusion is simple: a smart ring is valuable when its form factor solves a real tracking problem and the information remains useful. It is poor value when it only duplicates data you already have.

What Makes a Smart Ring Worth the Cost?

Buyers are not only paying for a small piece of hardware. They are paying for a complete experience that may include:

• sensors and a battery in a compact ring;

• a companion app;

• algorithms that turn signals into estimates and trends;

• charging hardware;

• software updates;

• customer support;

• warranty and return protection;

• cloud storage or integrations;

• optional or required subscriptions.

However, a high price does not prove that a product is accurate, durable, or well supported. Likewise, a low price does not automatically mean a ring is useless. Value comes from the relationship between the product and the buyer’s actual needs.

A ring becomes easier to justify when it delivers one or more of the following:

Better wear consistency

Wearables only collect useful longitudinal data when people actually wear them. A buyer who removes a watch every night may obtain more complete overnight information from a ring that feels comfortable.

Less screen friction

Some people want wellness information without calls, messages, app alerts, and another display. A ring can separate data collection from constant interaction.

Data during watch gaps

A ring may fill periods when a smartwatch is charging, removed for work, or replaced by a traditional watch.

Information that supports a real question

Examples include:

• Is my sleep timing becoming more consistent?

• Does late alcohol use appear alongside poorer overnight trends?

• Do I move less on work-from-home days?

• Am I recovering differently after a demanding week?

The ring does not answer these questions perfectly, but multi-day patterns may provide context. That is more valuable than collecting dozens of metrics without a clear reason to use them.

When a Smart Ring Is Worth It

You dislike wearing a watch to bed

For some users, a properly sized ring may feel less intrusive than a watch overnight. The advantage is not guaranteed superior accuracy; it is the possibility of more consistent wear.

Comfort varies with finger size, ring shape, skin sensitivity, swelling, temperature, and sleeping position. A sizing kit and an adequate trial period matter.

You want passive tracking without notifications

A smart ring can collect supported information without placing another interactive screen in your day. That may appeal to buyers who want fewer digital distractions.

You wear a traditional or dress watch

A ring can provide general wellness tracking while leaving the wrist available for a mechanical or conventional watch.

You care about sleep and resting trends more than live exercise data

Smart rings are generally designed around passive sensing and app-based review. They may provide useful context through sleep estimates, resting heart-rate patterns, HRV trends, movement, and other supported metrics.

These signals should be interpreted as wellness information, not as commands to train, rest, or change medical care.

You will use the app

A ring without a screen depends heavily on its companion app. The purchase is more likely to be worthwhile when the app explains trends clearly and the buyer regularly reviews them.

When a Smart Ring Is Not Worth It

You need live workout feedback

A ring is not the natural choice for users who want to see pace, distance, route, intervals, heart-rate zones, cadence, power, or navigation during exercise.

Some ring ecosystems can use a phone’s GPS or display workout information in an app. That is different from having built-in GPS and a display on the device itself.

Your smartwatch already solves the problem

If your watch is comfortable overnight, provides useful sleep and wellness information, and fits your charging routine, a ring may add another version of the same data rather than a new capability.

You expect medical answers

Consumer smart rings are generally wellness devices. They should not be used to diagnose disease, confirm a health condition, replace prescribed monitoring, or make treatment decisions.

A concerning symptom should be evaluated through appropriate medical care, regardless of what a wearable score shows.

You do not use wearable data

More information does not automatically improve behavior. If previous fitness trackers ended up unused in a drawer, a smaller form factor may not solve the underlying problem.

Daily scores make you anxious

Sleep, stress, readiness, and recovery scores can fluctuate. Some people find the information motivating; others become overly focused on achieving a “perfect” number. A product that increases anxiety may not be valuable even when its sensors perform as designed.

Are Smart Rings Worth It for Sleep?

Sleep is one of the strongest reasons to consider a smart ring, but the value comes mainly from wearability and consistency—not from assuming that a consumer device measures sleep like a laboratory.

What a smart ring can estimate

Depending on the model, a ring may combine:

• movement;

• heart-rate patterns;

• HRV;

• temperature-related signals;

• SpO₂ trends;

• timing and behavioral inputs.

Algorithms use these inputs to estimate sleep timing, duration, interruptions, and stages.

What it does not directly measure

Clinical polysomnography uses multiple channels that may include brain activity, eye movement, muscle activity, breathing, oxygen, and heart-related signals. A consumer ring does not reproduce that full process.

Research comparing consumer sleep technologies with polysomnography shows that performance differs by device and metric. A multi-device validation study found meaningful differences among consumer devices, reinforcing that results from one model should not be generalized to an entire category. See the peer-reviewed study, Accuracy of 11 Wearable, Nearable, and Airable Consumer Sleep Trackers.

Another study comparing Oura Ring Gen 3, Fitbit Sense 2, and Apple Watch Series 8 with polysomnography also illustrates why model-specific validation matters. See Accuracy of Three Commercial Wearable Devices for Sleep Tracking in Healthy Adults.

When sleep tracking can be useful

A ring may help a buyer notice patterns such as:

• inconsistent bedtimes;

• changes in estimated sleep duration;

• repeated nights with more interruptions;

• differences after travel, alcohol, late meals, or demanding exercise;

• longer-term changes in resting signals.

These observations may support awareness. They do not prove causation, diagnose a sleep disorder, or guarantee better sleep.

When it becomes redundant

A ring may add little when the user already wears a watch comfortably at night and receives sleep information they understand and use.

The best sleep-tracking device is not automatically the one with the most charts. It is the one the person can wear consistently without making sleep itself more stressful.

Are Smart Rings Worth It for Fitness?

Smart rings can support general fitness awareness, but they usually serve a different role from sports watches and dedicated training devices.

What rings may support

Depending on the model and app, a ring may provide:

• daily steps;

• general activity;

• estimated energy expenditure;

• workout logging or detection;

• resting-heart-rate patterns;

• HRV trends;

• sleep-related context;

• phone-assisted route or workout information.

What they usually do not replace

Serious runners, cyclists, hikers, and performance-focused athletes may still need:

• built-in GPS;

• maps and navigation;

• live pace or speed;

• heart-rate zones;

• lap and interval controls;

• cycling power;

• running dynamics;

• detailed strength-training records;

• a screen visible during exercise.

Understand where the data comes from

A useful evaluation separates the complete system into layers:

1. Ring sensors: What can the ring itself capture?

2. Ring hardware: Does the ring have a screen, GPS, vibration, or another output?

3. Phone app: What can the app display in real time?

4. Phone GPS: Does the phone provide route and distance information?

5. External sensors: Can a chest strap or cycling sensor add data?

6. Health platform: Which source becomes authoritative in Apple Health, Health Connect, or another platform?

A ring without a screen does not necessarily mean its entire ecosystem lacks live information. It does mean the buyer may need a phone or another device to see it.

For general activity and resting context, a ring may be enough. For detailed training execution, a smartwatch or sport watch is usually the more appropriate primary device.

Smart Ring vs Smartwatch or Fitness Band

Priority	Smart Ring	Smartwatch	Fitness Band
Screen-free wear	Strong fit	Weak fit	Mixed
Notifications and apps	Usually limited	Strong	Moderate
Live workout display	Usually limited	Strong	Moderate
Built-in GPS	Model-dependent and uncommon	Common on many models	Model-dependent
Overnight comfort	Personal preference	Personal preference	Personal preference
Professional discretion	Often strong	Model-dependent	Often visibly sporty
Passive wellness trends	Common focus	Common	Common
Sport-specific analytics	Usually limited	Often stronger	Usually basic to moderate
Traditional-watch compatibility	Leaves wrist free	Occupies wrist	Occupies wrist

No device category is universally better. The right choice depends on which compromises matter least.

Choose a smartwatch when interaction, navigation, communication, and live workouts matter most.

Choose a fitness band when cost, basic activity, and a small wrist display matter most.

Choose a smart ring when passive, screen-free tracking and a ring form factor solve a meaningful problem.

Is a Smart Ring Worth It If You Already Own a Watch?

Sometimes—but only when it fills a gap.

A ring may complement a watch when:

• the watch is uncomfortable during sleep;

• the watch charges overnight;

• the user wants to wear a traditional watch;

• the watch is removed in certain work or social settings;

• the ring app provides a distinct interpretation the user values.

A ring may be redundant when:

• the watch is already worn consistently;

• the watch provides useful sleep and resting trends;

• the user prefers one health app;

• the second device creates conflicting records;

• the ring does not change any decision.

Two devices can also complicate data management. Health platforms may receive duplicate steps, workouts, sleep sessions, or heart-rate records. Buyers should check which device or app is treated as the preferred source.

How Accurate Are Smart Rings?

There is no honest category-wide answer.

Accuracy depends on:

• the exact model;

• firmware and algorithm version;

• the metric;

• ring fit;

• sensor contact;

• movement;

• circulation;

• skin and environmental conditions;

• the comparison method used in a study.

Direct signals, proxies, and estimates

It helps to distinguish several output types:

Sensor readings: Signals captured by optical, motion, temperature, or other sensors.

Physiological proxies: Signals used as indirect indicators of another state.

Algorithmic estimates: Calculations such as sleep stages, calories, or workout classification.

Composite scores: Manufacturer-defined combinations such as sleep, readiness, stress, or recovery scores.

Clinical measurements: Outputs produced by validated medical methods for a defined use.

A number can look precise while still being an estimate.

Metric-specific expectations

Resting measurements often occur under more stable conditions than vigorous exercise, but performance still varies by device and person.

Exercise heart rate can be affected by motion, grip, circulation, and sensor contact.

Sleep duration and sleep stages are not equally easy to estimate. Consumer devices may perform better on some broad sleep-wake measures than on detailed stage classification.

Calories are calculated from assumptions and personal inputs rather than measured directly.

SpO₂ outputs from consumer devices should be treated according to the manufacturer’s stated intended use. General wellness trends should not be treated as a substitute for a medical pulse oximeter when medical evaluation is required.

A 2025 systematic review of smart rings in clinical research described promising results but also highlighted variation in devices, applications, and evidence. It should not be read as proof that every commercial ring is clinically accurate. See Smart Ring in Clinical Medicine: A Systematic Review.

The best rule is: evaluate evidence for the exact model and exact metric, then use personal trends cautiously.

Subscription and Total Cost of Ownership

The purchase price is only one part of value.

Use this formula:

Hardware price + required membership during expected use + optional services you genuinely plan to use + necessary accessories + disclosed return or sizing costs

Current subscription examples

As of August 5, 2026:

• Oura’s current support materials state that membership pricing and availability depend on region. Buyers should review the current Oura Membership information before purchasing.

• RingConn currently markets the RingConn Gen 3 with no required subscription and model-specific battery claims.

• Ultrahuman states on its Ring AIR purchase page that recurring fees are not required to access ring data. It also offers an optional UltrahumanX extended-coverage program.

• Samsung’s current Galaxy Ring page presents the ring within the Samsung Health ecosystem without a separate mandatory ring-data subscription on that page.

These policies can change. “No required subscription” also does not mean every protection plan, future service, integration, or add-on will always be free.

What to check before buying

• Which features work without a subscription?

• What happens after cancellation?

• Can historical data still be viewed?

• Can data be exported?

• Does the subscription price vary by country?

• Are advanced coaching or AI features optional or required?

• Is the charger or charging case included?

• What does a replacement charger cost?

• Are return shipping or restocking fees possible?

• Does a sizing-kit purchase convert into credit?

Do not assume that a no-subscription product is automatically better. A clear, useful app with a fee may provide more value to one buyer than a confusing free app. The correct comparison is total cost versus actual usefulness.

Battery, Comfort, Sizing, and Durability

Battery

Manufacturers publish different battery estimates for different models and sizes.

For example, Oura currently advertises Oura Ring 5 with up to nine days of battery life. RingConn advertises model-specific ranges on the Gen 3 product page. Samsung notes that Galaxy Ring battery life varies by size and can reach up to seven days in its Galaxy Ring support overview.

“Up to” is not the same as typical performance for every user. Actual runtime can vary with:

• size;

• enabled features;

• signal quality;

• synchronization;

• charging habits;

• battery age;

• temperature;

• firmware;

• use patterns.

The useful question is not which marketing number is largest. It is whether the charging routine avoids losing the data you care about.

Comfort and sizing

Use the manufacturer’s sizing kit whenever available. Smart-ring sizing may differ from conventional jewelry sizing, and different generations from the same brand may use different kits.

Test the sample size:

• during sleep;

• after exercise;

• in warm and cool conditions;

• during typing;

• early and late in the day.

A ring should maintain appropriate sensor contact without causing numbness, pain, or excessive pressure.

Durability

Scratch resistance depends on the full material and finish system—not only whether a page says titanium, steel, ceramic, or aluminum. No daily-wear smart ring should be assumed to remain scratch-free.

Removing any rigid ring is generally prudent when:

• bars or dumbbells press against it;

• climbing equipment may catch it;

• tools create crush or snag risks;

• manual work could damage the ring or finger.

Check the exact manufacturer’s care and safety instructions.

Rechargeable-battery aging

Rechargeable batteries degrade over time. Actual usable life varies by model, charging habits, heat exposure, physical wear, software support, and service policy.

There is no reliable universal “two-year” or “three-year” lifespan for the category. Buyers should review warranty terms and whether battery service or device replacement is available.

App Quality, Privacy, and Data Ownership

A smart ring is largely an app experience. Sensor data has limited value when synchronization is unreliable or the app does not explain what its outputs mean.

App questions

• Are trends easy to understand?

• Can incorrect workouts or sleep sessions be edited?

• Does synchronization happen reliably?

• Does the app explain estimates and limitations?

• Can the user export data?

• Does it integrate with the preferred health platform?

• Can duplicate sources be managed?

• Is support accessible?

• Are essential functions hidden behind later paywalls?

Privacy questions

Before buying, review:

• what information is collected;

• why it is collected;

• whether it is shared or sold;

• whether advertising or analytics partners receive it;

• where it is stored;

• how long it is retained;

• how account deletion works;

• how data export works;

• what happens if the service closes or changes ownership.

Do not assume that all consumer wearable data is protected by HIPAA. The U.S. Department of Health and Human Services explains that HIPAA applies to covered entities and business associates and generally does not protect all information stored on personal phones or consumer apps. See Protecting the Privacy and Security of Your Health Information When Using Your Personal Cell Phone or Tablet.

HHS also provides a mobile health app regulatory resource to help determine which federal rules may apply.

Privacy quality is part of product value. A cheaper ring with an unclear company and vague privacy policy may carry costs that do not appear on the checkout page.

Are Cheap Smart Rings Worth It?

A budget ring can be reasonable when the goal is to test the form factor or obtain simple general-awareness features without a major investment.

However, buyers should not judge the product by price alone.

Look for:

• an identifiable manufacturer;

• a maintained app;

• clear compatibility requirements;

• an accessible privacy policy;

• realistic claims;

• a usable sizing process;

• a clear return policy;

• customer support;

• model-specific specifications;

• evidence for any accuracy claim.

Common risks include limited independent validation, weak software support, unclear sensor specifications, vague privacy practices, and difficult returns.

A low price does not prove inaccuracy. A high price does not prove accuracy. The most important question is whether the product’s claims can be verified and whether the seller supports it after purchase.

Should You Buy Now or Wait?

Buy based on current functions—not promised roadmaps.

Consider buying now when:

• the current model solves a specific problem;

• compatibility is confirmed;

• the ring fits your budget;

• the return policy allows meaningful testing;

• current features are sufficient without future updates;

• you accept that outputs are general wellness estimates.

Consider waiting when:

• a required feature is missing;

• the product does not support your phone;

• your size is unavailable;

• the return policy is weak;

• you do not know how you would use the data;

• you already have equivalent information;

• the purchase depends on a future software promise.

Technology will continue to improve, but waiting for a perfect wearable can become endless. The better decision rule is whether today’s product offers enough present value.

The Existing Watch Redundancy Test

Before buying a ring in addition to a watch, answer these questions:

1. Do I already wear my watch comfortably overnight?

2. Does my watch already provide sleep and wellness information I understand?

3. Will the ring fill a real gap during charging, work, sleep, or formal settings?

4. Will managing two apps and data sources create more friction?

5. Would I still want the ring if its trends were similar to my watch?

A ring is more likely to add value when it solves a specific unmet need. It is less likely to add value when it simply creates a second version of the same information.

A 30-Day Smart Ring Value Test

Use as much of the applicable return or trial period as the manufacturer allows. Do not assume every seller provides 30 days.

Week 1: Fit, setup, synchronization, and charging

• Confirm the size across different times of day.

• Test overnight comfort.

• Check pairing and synchronization.

• Learn which metrics come from the ring, phone, or another source.

• Establish a charging routine.

• Verify that the advertised core features are actually available.

Week 2: Data consistency and gaps

• Look for missed sleep sessions or unexplained gaps.

• Compare major trends with an existing device, without expecting identical numbers.

• Check whether workouts are recorded appropriately.

• Review whether the app explains unusual values.

• Note skin irritation, pressure, or fit problems.

Week 3: Practical usefulness

• Identify one decision the ring supported.

• Ask whether it changed bedtime, activity, rest, or another routine.

• Notice whether scores create clarity or anxiety.

• Check whether you review the app because it is useful or merely because it is new.

• Decide whether the data adds anything beyond your watch or phone.

Week 4: Long-term value

• Inspect scratches and signs of wear.

• Recalculate total cost.

• Evaluate subscription value if applicable.

• Consider the charging burden.

• Review privacy and export options.

• Test customer support if an issue arose.

Final questions

• Did I wear it consistently?

• Did it answer a question I care about?

• Did it support at least one useful decision?

• Did it add information beyond my existing device?

• Did it create clarity or score anxiety?

• Is the total cost acceptable?

• Would I notice if I stopped wearing it?

• Would I replace it if it were lost?

A “no” to most of these questions is a strong reason to return it within the applicable policy.

How to Choose the Right Smart Ring

Start with one primary purpose

Choose the main reason first:

• sleep continuity;

• screen-free tracking;

• general activity;

• resting trends;

• traditional-watch compatibility;

• no-subscription ownership;

• ecosystem integration.

A ring bought for one clear purpose is easier to evaluate than a ring bought for “better health.”

Verify the exact model

Do not assume every model from a brand has the same:

• sensors;

• battery;

• sizes;

• charger;

• app features;

• water-resistance rating;

• subscription;

• phone compatibility;

• integrations.

Check the app before purchasing

Read the current app description, compatibility requirements, recent update history, and privacy disclosures.

Review returns before opening or wearing

Some policies contain conditions related to:

• sizing kits;

• opened packaging;

• cosmetic wear;

• shipping charges;

• restocking;

• marketplace sellers;

• region;

• return authorization.

Use model-specific evidence

Look for research involving the exact device generation and metric. A sleep study on one model does not validate another model’s HRV, calories, or SpO₂.

Avoid medical overclaims

Be cautious when a consumer ring claims to diagnose, treat, prevent, or confirm medical conditions without clearly identified regulatory authorization for that specific intended use.

Where BKWAT Fits

BKWAT is positioned for buyers who prefer screen-free general-wellness tracking and do not want a required recurring subscription for the core features currently listed for the selected model.

The current BKWAT product page for its Smart Ring for Women and Men lists features including sleep monitoring, heart-rate information, HRV, blood-oxygen trends, activity functions, IP68-rated water resistance, iOS and Android compatibility, a charging case, and no subscription fee. Buyers should use that specific product page to verify current colors, sizes, included accessories, price, and feature access before ordering.

These features are intended for general wellness and fitness awareness. They should not be presented as medical diagnosis, clinical monitoring, or proof of a health condition.

BKWAT’s product direction can be summarized through three principles:

More Accurate

This means working toward clearer and more consistent everyday wellness trends. It does not mean medical accuracy, clinical validation, or proven superiority across every metric.

Faster

This means reducing friction in pairing, synchronization, and access to supported wellness information. It should not be interpreted as a guaranteed speed advantage over every competitor.

Longer

This means reducing avoidable charging interruptions through power-conscious design and portable charging support where included. It does not mean unlimited battery life or verified industry-leading runtime.

BKWAT may be considered by buyers who value screen-free tracking, a currently subscription-free core experience, and straightforward general wellness information.

It is not the appropriate choice for someone seeking built-in GPS, live pace feedback, clinical decision-making, medical diagnosis, or highly specialized athletic analysis.

Final Verdict

Smart rings are worth it for some buyers, not because rings are universally better than watches, but because the form factor can solve specific problems.

A ring may be a good purchase when:

• a watch is uncomfortable overnight;

• screen-free tracking is important;

• the wrist is reserved for another watch;

• passive data continuity matters;

• the app provides understandable information;

• the buyer accepts the limitations;

• the total cost is reasonable.

A ring may be poor value when:

• an existing watch already meets the same need;

• live fitness features are the priority;

• the buyer expects medical answers;

• the device will not be worn consistently;

• scores increase anxiety;

• the purchase depends on future promises;

• recurring costs feel uncomfortable.

The decisive question remains:

What must be true for this smart ring to remain useful after the first month?

When the answer involves a real problem, consistent wear, a useful app, acceptable cost, and practical decisions, a smart ring can be worthwhile.

When the answer is mainly “it collects more data,” it probably is not.

Frequently Asked Questions

Are smart rings actually worth it?

They can be worth it when passive, screen-free tracking or overnight wear solves a problem that another device does not solve. They are less valuable when they duplicate an existing smartwatch.

Are smart rings worth it for sleep?

They may be useful for people who find a properly sized ring easier to wear overnight than a watch. Sleep duration and stages remain algorithmic estimates and should not be treated as clinical measurements.

Are smart rings worth it for fitness?

They can support general activity and resting trends. Buyers who need built-in GPS, maps, live pace, intervals, or detailed sport metrics will usually be better served by a sport watch.

Can a smart ring replace a smartwatch?

It can replace a watch for buyers who only need passive wellness tracking. It cannot replace the screen, notifications, navigation, apps, and live workout controls of a smartwatch.

Is a smart ring worth it if I already own an Apple Watch or another smartwatch?

Only when the ring fills a real gap, such as overnight comfort, charging periods, formal wear, or a preferred app experience. Otherwise it may be redundant.

How accurate are smart rings?

Accuracy varies by device, metric, fit, firmware, activity, and person. Evidence for one model cannot be generalized to every ring. Treat most outputs as wellness signals, estimates, or trends unless a specific medical use has been properly validated and authorized.

Do smart rings require subscriptions?

Some do and some do not. Verify what works without a subscription, what remains available after cancellation, and whether optional paid services exist.

Are cheap smart rings worth trying?

They may be suitable for testing the form factor or obtaining basic awareness features. Check the manufacturer, app support, privacy policy, returns, and evidence behind claims.

How long should I test a smart ring?

Use as much of the applicable return period as possible. Evaluate fit, charging, app quality, data consistency, practical usefulness, total cost, and whether you would miss it after stopping use.

Who should not buy a smart ring?

People seeking medical diagnosis, advanced live sports features, or automatic health improvement should not rely on a smart ring for those goals. It may also be a poor purchase for anyone who already ignores wearable data or becomes anxious about daily scores.
