Stress Check: HRV for Watch
Recovery Score & Calm Tracker
Free · In‑App Purchases
Stress Check turns your Apple Watch into a personal stress and recovery tracker. In about a minute it reads your heart rate variability (HRV) — your nervous system's clearest signal of how well you're coping — and turns it into one simple recovery score.
No gadgets, no guesswork. Just breathe, and your wrist does the rest.
WHY HRV?
Your heart never beats like a metronome. The tiny differences between beats reveal the balance between stress and recovery in your nervous system. Higher variability usually means you're well recovered; lower variability can point to stress, fatigue, or poor sleep. Stress Check measures it and explains what it means for you.
WHAT YOU GET
• A clear 0–100 recovery score after every measurement
• A guided 60-second breathing measurement on Apple Watch
• Trends that show how your stress and recovery shift across days and weeks
• Personal insights that learn your normal — your own baseline, not a generic average
• Factors that reveal what truly affects you: sleep, caffeine, workload and more
• On-device AI that puts your numbers into plain, honest words
• A Home Screen widget and watch complication, so your score is always a glance away
BUILT AROUND YOU
Stress Check compares every reading to your own baseline — seeded from your age and sex, then refined as you measure. The more you use it, the better it understands your unique patterns.
HONEST BY DESIGN
This is a wellness app, not a medical device. HRV reflects part of your stress, not all of it, and Stress Check says so plainly. Scores are estimates to help you notice patterns and take better care of yourself — never diagnoses.
PRIVATE BY DEFAULT
Your health data is processed entirely on your device and is never sent to us or shared. Optional iCloud backup keeps a copy in your own private iCloud, so you can restore everything after reinstalling.
STRESS CHECK PLUS
Go deeper with Plus: full history, advanced trends, factor correlations, on-device AI summaries, cycle-aware recovery and exportable reports. Available weekly, monthly or yearly, or as a one-time lifetime purchase.
Measure. Understand. Recover.
StressCheck is a wellness app, not a medical device. It does not diagnose, treat, cure, or prevent any disease or condition. Always consult a qualified healthcare professional before making any health or medical decisions.
