Fasting basics, troubleshooting
16 hours of fasting, 8 hours of eating window. Most common form of intermittent fasting. Example: stop eating at 8pm, resume at noon next day.
Talk to your doctor. Intermittent fasting is generally safe for healthy adults but not recommended for pregnant or breastfeeding women, people with diabetes, eating disorders, or certain medical conditions. Not Another Fasting Timer is a tool, not medical advice.
Yes. Water, black coffee, plain tea, and electrolyte powders without sugar are typically fine. Anything with calories breaks the fast.
Tap "End fast" → the app saves the partial fast to history and resets. Streaks count completed fasts only — partial doesn't break the streak unless explicitly marked as a "broken fast".
iOS schedules widget refreshes — typically every 15 minutes to 1 hour. Force refresh: long-press → Edit Widget → Done. Or open the app once.
Settings → Notifications → Not Another Fasting Timer → Allow. iOS Focus mode may suppress non-Time Sensitive alerts. The fast still completes; the alert just didn't visually show.
Coming soon to the App Store. iOS 17+, free.
