Minutes chips run 1, 2, then 5 through 90 in 5-minute increments — twenty values that read like a slider but tap like buttons. The chips themselves are bare numbers; the unit "Minutes" lives in the section header so the row stays short and dense. 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):
- Guided
- Unguided
- Body scan
- Breath awareness
- Loving-kindness
- Visualization
- Mantra
- Open awareness
- Other
If you don't want to attribute a technique, just don't tap one. The session saves as untyped — minutes and date are enough.
