Minutes chips run 1, 2, then 5 through 90 in 5-minute increments — twenty values that cover a 1-minute box-breathing reset before a meeting all the way through a longer Wim Hof round on a Sunday morning. The chips are bare numbers; the unit "Minutes" lives in the section header. There is no Custom field and no number pad: the chip set covers every length the app cares about.
Tap a Minutes chip and the session auto-commits. No Add Session button, no submit. Tap a different chip to swap durations. Tap the same chip again to remove the session. Swipe the sheet down when you're finished.
Once a Minutes value is selected, the Type chips brighten and become tappable (optional):
- Simple / Slow breathing
- Box breathing
- 4-7-8 breathing
- Coherent (5-5) breathing
- Cyclic sighing
- Alternate nostril
- Wim Hof
- Other
If you don't want to label the technique, just don't tap one. The session saves as untyped — minutes and date are enough.
