What BreathFriend shows
On supported devices and with appropriate permissions, BreathFriend can display recovery snapshots around sessions and longer-term trend views. Availability depends on the watch, sensor support and data permissions.
Health Connect integration
Health Connect can provide a shared Android data layer for supported health information. BreathFriend uses the integration only where the app and device support the relevant flow.
What HRV cannot tell you by itself
A single HRV value is not a diagnosis, and a higher number is not automatically better in every context. Sleep, activity, illness, stress, device fit and measurement timing can all affect readings.
Important limitationBreathFriend is not a medical device. Do not use its recovery views to diagnose a condition or make treatment decisions.
To focus on the breathing experience itself, read the Wear OS guide or compare guided breathing exercises.
