A mindful breathing timer for iPhone + Apple Watch
Make space to breathe.
Halo guides you through calming breath work with slow-breathing animation and gentle haptic cues. Pick a pattern, set a timer, and let your wrist or your phone keep the rhythm — then watch your streak and Chill-O-Meter grow.
No account. No ads. Your data stays in your iCloud.
What’s inside
Start with Coherent (5-5), Relax (4-7-8), or Box (4-4-4-4) — or dial in your own inhale, hold, exhale, and rest, one second at a time.
A gentle tap marks every phase change, so you can close your eyes and just breathe. No sounds until your session ends.
Start a session from your wrist with haptic cues, or glance at the rings while a session runs on your iPhone.
A daily streak, a 12-week heatmap, and a Chill-O-Meter that fills up as your practice grows.
Quick-start widgets on your Home Screen and a live countdown in the Dynamic Island while you meditate.
Sessions log as mindful minutes in Apple Health, and your history syncs privately through your own iCloud.
