## What is OptiSense?

OptiSense helps you understand your sleep, stress and recovery using Apple Watch and Apple Health data. See your daily readiness estimate, explore your trends and ask an AI coach for practical guidance.

ALL FEATURES CURRENTLY FREE

No subscription is required to access any feature. Each device includes 20 AI answers and 10 food scans per day. Daily allowances reset at local midnight, and remaining usage is shown in the app.

UNDERSTAND YOUR DAY

View readiness, stress and recovery estimates alongside sleep, heart rate variability, resting heart rate and activity. Explore the measurements behind your scores and follow changes over time.

ASK YOUR COACH

Get guidance on recovery, sleep, nutrition, exercise and everyday wellbeing. Choose from 10 coaching languages, read replies or listen with a matching Apple voice. Preview and save your voice choice in Profile → Voice → Language & Voice. The 20-answer daily allowance is shared between Coach and Ask Expert; a reply with spoken audio counts as one answer.

CHOOSE YOUR NEXT STEP

Explore suggested actions, breathing exercises and habit tracking. Use forecasts and what-if scenarios to explore possible changes to your routine. Forecasts are estimates, not promises of future health outcomes.

EXPLORE YOUR NUTRITION

Photograph a meal to estimate calories and macronutrients, then review and correct the result. Food recognition and portion estimates can be imperfect. Includes 10 successful scans per day.

KEEP YOUR PROGRESS IN VIEW

Review your health history, workout information and trends without subscribing.

APPLE WATCH COMPANION

See recovery, stress, sleep and HRV around a central coaching button. Access local coaching without using your iPhone cloud-answer allowance. Your nearby iPhone can prepare speech using your selected Apple voice. Local translation requires a paired iPhone with iOS 26 or later and downloaded language packs; availability varies by language. Available insights depend on the measurements you share through Apple Health.

YOUR DATA AND CHOICES

Choose which Apple Health data to share with OptiSense. Cloud coaching and food analysis use external services to process the information needed for those features. Selected Apple voices and downloaded translation packs run locally. Review the privacy policy and in-app settings for details.

EXISTING SUBSCRIBERS

All features are currently free, but existing subscriptions do not cancel automatically. To stop renewal, use Manage Subscription in Profile or manage your subscriptions through your Apple account.

OptiSense provides general wellness information. Scores, forecasts, AI responses and food estimates are not medical diagnoses or a substitute for professional care.

### 1.0.9 — 2026-05-13

Bug fixes and reliability improvements:

  • Fixed false "Critical Recovery Needed" alerts. The notification was incorrectly triggered by an old low‑readiness day in your history instead of your actual current score — so
  users with healthy recovery were still receiving the warning every day. Critical recovery alerts now correctly use your latest score.

  • Fixed "Positive Adaptation" insights firing when readiness was declining instead of improving. The two-week comparison was reading recent and older weeks in the wrong order.

  • Fixed HRV Crash detection comparing the wrong samples — it was checking your oldest HRV reading against a baseline that excluded today's data. It now correctly compares today against your 13‑day baseline.

  • Fixed peak performance and recovery opportunity insights using the wrong day's score. They now reflect your current state.

  • Fixed risk predictions (declining readiness, accumulating stress) that could be triggered by improving trends due to a slope-direction error.

  • General stability improvements and added test coverage to prevent these regressions.

### 1.0.8 — 2026-04-18

• More accurate Recovery Score — the Activity contributor now uses yesterday's full-day energy burn (kCal) instead of today's partial   
  total, so your score properly reflects recovery from yesterday's exertion.                                                            
 • Clearer labelling — Contributor Metrics now explicitly show they're based on yesterday's data, so you always know what's driving your score.

### 1.0.7 — 2026-04-11

Bug Fix: Fixed a persistent false notification reporting "HRV has dropped to 0ms" even when heart rate variability data was normal. The issue occurred when HealthKit had no HRV samples available — the missing data was incorrectly interpreted as a real zero reading, triggering critical alerts. HRV alerts now correctly ignore missing data.
