Why watch-first breathing feels different
A phone can be a useful setup tool, but it is often the wrong object to hold during a quiet breathing break. BreathFriend moves the active guidance to the watch so the session can begin with less friction and remain more private.
The Android companion still matters for browsing, detailed setup, history and recovery trends. The Wear OS app handles custom practice, sensory guidance and supported HRV capture around the session.
How guidance works on the watch
BreathFriend can represent the current inhale, hold or exhale phase through several independent cue types. Choose a minimal setup or layer the guidance that fits the environment.
- Haptic patterns: feel phase changes without looking at the screen.
- Transition sounds: use clear, separate phase-change cues.
- Selectable voices: choose the transition voice you want to hear.
- Background audio: add music or an ambient soundscape during the session.
- Visual guidance: see the current phase, timing and breathing path.
- Tiles and complications: reduce the number of taps before starting.

On supported devices, BreathFriend can measure HRV before and after a guided session, show the change and build recovery trends across repeated practice. The feature is optional and designed as wellness context, not continuous clinical biofeedback.
Useful moments for a watch-based session
A smartwatch guide is especially useful when opening a phone would add distraction. Common examples include a short reset before a meeting, a focus break between tasks, a commute, a quiet moment in public or a bedtime routine.
For the most subtle setup, continue to the screen-off breathing guide. For recovery details, read the HRV guide.
