One tap on your Apple Watch logs the drink. Next morning, Fewer reads your own sleep, heart rate, and HRV against your dry-night baseline, and prints the honest slip.
After 3 drinks, your sleep ran 1h 5m below your baseline.
The Watch is the whole capture story: raise your wrist, tap once, feel the thunk. Your saved drinks are one turn of the crown away, and a shake undoes an honest mistake.
Every morning, Fewer compares last night against the median of your own confirmed dry nights: sleep, sleeping heart rate, and morning HRV, sample counts printed on every claim.
Real drinking has seasons: a heavy December, a dry stretch, a deliberate return. Fewer charts the year the way it actually ran, dry periods shaded beside your weight line, spend counted in your own currency.
A moderation app earns trust by what it will not do. These are permanent, written into the spec.
Everything Fewer knows lives on your iPhone and in your Apple Health record, synced only through your personal iCloud. Delete the app and its data is gone; export it any time as files you own.
