Fastful — the calm fasting timer
Fasting is the art of not doing. Strange, then, that most fasting apps are so busy — accounts, coaches, paywalls, notifications engineered to pull you back in. Fastful is one beautiful ring on your iPhone, Apple Watch, and Home Screen. It keeps perfect time, then gets out of your way. You fast. It counts.
No pressure
Streaks and milestones celebrate showing up — and forgive a day off. No dopamine loops, no "streak in danger", no guilt engineered into a timer.
No subscription
Pay once and it's yours forever. Fastful costs less than the lunch you're skipping.
No personal data
No account, no ads, no tracking across apps. Your history lives on your phone — we couldn't read it if we wanted to.
Read our privacy policyNo lock-in
Your fasting history exports to CSV in one tap and opens in any spreadsheet. It's your data — take it anywhere.
It counts what others cut off.
Past your goal, the ring keeps going. Hour 17 of a 16-hour fast is the one you're proudest of — your discipline doesn't stop at 100%, and neither does Fastful.
Whatever your reason
For health
Run 16:8, 18:6, 20:4, OMAD, or any custom window. Start with two taps, glance at the ring, get on with your day.
For faith
A quiet companion for fasting days. No food ads, no calorie lectures — just the time, kept faithfully, while you stay present.
For longevity
Take on 24 to 72-hour resets with a timer built for the long haul: elapsed, remaining, and every extra hour counted.
For discipline
Streaks, totals, and trends that keep score the way a good friend would. The honest work of showing up, made visible.
