About this app
The free fasting timer that forgives you when life happens. No premium. No tricks.
PureFast is a simple intermittent fasting timer and personal log. Everything is free: the timer, your history, your schedules and your export. There is no account and no sign-up, and your data stays on your phone.
FORGIVING BY DESIGN
- Start a fast now, or tell the app you stopped eating earlier and it counts from then.
- Forgot to tap End fast? Use "I stopped earlier" and pick the time you really stopped.
- Edit the start time or the goal at any time, add a fast you forgot, edit or delete past fasts.
- Undo after changes, so a wrong tap never costs you your history.
- Calm wording: no red failure screens and no "you failed" messages.
FLEXIBLE SCHEDULES
- Set a different goal for each day of the week, with quick choices such as 12:12, 14:10, 16:8, 18:6 or one meal a day.
- "Today is different" changes only today.
- Optional reminder days for 5:2 or alternate-day patterns, kept separate from your fasting hours.
PROGRESS WITHOUT GUILT
- A weekly view shows the days you showed up and the days you reached your goal.
- A monthly calendar shows your fasts. Tap a day to see every fast as a box that fills up to show how much of the goal you completed.
- There are no streaks, so one missed day never "breaks" anything.
REMINDERS YOU CONTROL
- Everything is off until you turn it on: goal reached, a one-hour heads-up, and a start-time reminder.
- Quiet hours keep the phone silent at night.
HOME-SCREEN WIDGET
- See your current fast on your home screen with a live clock.
YOUR DATA IS YOURS
- No account. Data is stored on your device.
- Save a full backup file, or export your fasts as a spreadsheet (CSV), and restore them on a new phone.
- Light, dark or automatic theme.
JOURNAL
- Optionally note hunger, energy and mood for any fast, and see simple averages of your own notes.
ADS
The app is free because it shows ads from Google AdMob. The app works fully offline. You can watch one short ad to unlock the backup file; Export CSV never needs an ad.
IMPORTANT
PureFast is a timer and personal log. It is not medical advice and does not diagnose, treat or prevent any condition. Fasting is not suitable for everyone, including children and teenagers. If you are pregnant or breastfeeding, have diabetes or take medicine that affects blood sugar, have had an eating disorder, or have any other health concern, talk to a doctor before you fast. Stop and get medical help if you feel unwell.
