Breathe
Blow into your microphone to fill the spirometer. Calibrate once, then beat your target with every breath.
Tap start and allow microphone access.

How it works
- Blow mode calibrates once (blow your hardest), then each breath fills the bar toward your target — a microphone stand-in for an incentive spirometer.
- Paced mode follows your breathing rhythm near the mic instead of volume.
- Loudness isn't millilitres, so reported volumes are relative to your calibration — honest about the proxy.
