Forgot to start the timer? Fix it in two taps.
Dawnwell is an intermittent fasting timer built around the one thing that actually breaks a fasting habit: you forget. Start late, end late, remember it the next morning - every window stays editable, so your log ends up matching what you really did.
START IN ONE TAP
No sign-up, no onboarding quiz, no account. Open the app, tap once, and the countdown to your goal runs to the second - even after you close the app or restart your phone.
FIX ANY RECORD, ANY DAY
Tap a past window to change its start or end, switch fasting to eating, or delete it. Missed a whole day? Add the window straight from the calendar. The app blocks only what is genuinely wrong: overlapping windows and times in the future.
SEE WHERE YOU ARE IN THE FAST
A stage strip shows the six phases of a fast - fed, glycogen use, fat burning, ketosis, autophagy and deep fast - with the time left until the next one. Tap it for a detailed view. Informational only, not medical advice.
YOUR WHOLE MONTH IN ONE CALENDAR
The Timeline tab draws every fasting and eating window as a bar, day by day. Open a day to read and edit its windows, its water entries and its weight.
PLANS WITHOUT LIMITS
16:8, 18:6, 20:4, OMAD, or count-up with no goal at all. Build your own plan with any number of hours. Every plan is open to everyone, with no subscription.
INSIGHTS THAT STAY YOURS
Current streak and streak freezes, longest fast, average duration, goal-reached ratio, a weekly chart, your weight trend, mood and energy from your journal, and achievements that unlock as you go.
A JOURNAL FOR EACH FAST
When a fast ends, log how it felt in one screen - mood, energy and a note. Skip it whenever you want.
REMINDERS THAT RESPECT YOU
One notification when your fast is done, and an optional daily reminder to start. Nothing else.
YOURS, AND OFFLINE
Everything is stored on your device. No account, no cloud, no sharing. Export every window, weight and water entry to CSV whenever you want.
Dawnwell is supported by a small banner and one full-screen ad when you open the app - never while you are starting or ending a fast. If you would rather not see them, one purchase removes every ad permanently. There is no subscription, and nothing else is locked behind it.
Forgot to start? Edit any past window and keep your fasting log honest.
