Before you buy
Your phone already does this
- Clock times things. Clock › Timers counts down a fast of any length.
- Notes keeps a journal. Write down how it went in a note.
- Health records your weight. Health › Body Measurements › Weight, typed in or from a smart scale.
If that’s all you need, keep your seven dollars.
What we add
- Fasts you can fix. Start now or earlier, change the goal mid-fast, end at the real time. Presets from 12:12 to 20:4, your own, or open-ended. Stopping early still counts as a fast.
- History is the point. A calendar, a list and a thirteen-week heatmap of the same records. Every year stays open, searchable and editable.
- A private journal. An intention before, notes on mood, energy and hunger during, a reflection after.
- Trends without scores. Hours, sessions and typical length by week, month, quarter and year, plus weight, water, waist and sleep if you want them. No streaks to break.
- Lock Screen and wrist. Widgets, a Live Activity, and an Apple Watch app that starts and ends fasts and logs water.
- Yours to take. JSON and CSV export, and an import that checks everything before it changes anything.
