Common questions

Can I download WatchHRV now?

Not yet. WatchHRV is in development for iPhone. This page describes what is planned; download details will appear here once the app is actually released.

Do I need an Apple Watch?

No. WatchHRV reads compatible HRV readings already stored in the iPhone Health app. An Apple Watch is one common source, but it is not required when compatible data is available. HRV kept only in another company's app, and not written to Apple Health, can't be used.

Which HRV measurement does it use?

Apple Health's heart rate variability (SDNN) readings, in milliseconds. Daily values are the average of the readings available that day, and period cards average those daily values.

Will I need to pay for anything?

No. ALL FEATURES ARE FREE. An optional supporter subscription ($0.99/week, $1.99/month or $19.99/year in the US) will remove ads and automatic signup reminders only. Final prices will follow the App Store listing and may vary by region.

Is WatchHRV a medical app?

No. It shows trends in your own readings and an optional personal target. It gives no diagnosis, recovery score or medical advice.
