FastingTracker: Fasting Timer
Intermittent fasting timer
$0.99 · Designed for iPhone. Not verified for macOS.
FastingTracker is the lean intermittent fasting timer for Apple Watch. Everything runs right on your watch: independent of your iPhone, no account, no ads.
FAST WITH ONE TAP
Pick a plan, tap "Start fast" and see at a glance how long is left. A colored ring shows progress and phase: fasting, eating window or ready.
PLANS
• 16:8, 18:6, 20:4, OMAD and 36 h
• Custom plan: 1 to 72 hours of fasting, 1 to 24 hours of eating window
• Optional daily schedule: fasting and eating run at fixed times every day, across midnight and daylight saving changes
COMPLICATIONS
Ring, time left and phase right on your watch face: circular, corner, rectangular and as a line of text. The ring runs live without taxing your watch.
NOTIFICATIONS
If you like, a reminder one hour before your fast ends and when it ends, so you never miss the moment to eat.
HISTORY AND STREAK
Your last 30 fasts, your current streak and how often you reached your goal.
ADJUST START TIME
Started too late? Move the start time back to when you really began.
PRIVATE AND FAIR
One-time purchase, no subscriptions, no in-app purchases, no ads. All data stays on your watch. No sign-in, no analytics, no tracking.
Note: FastingTracker is not a medical product and does not replace medical advice. Fasting is not suitable for everyone, for example during pregnancy, with eating disorders, diabetes or underweight. If you have a health condition, talk to your doctor first.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• A manually started fast now continues past your goal until you end it. The app and complication show the time beyond your goal.
• The eating window now starts when you end your fast.
• Past the goal, the app and complication show a checkmark, and nothing gets cut off anymore.
• The goal-reached notification now comes through even in Focus or Sleep mode and vibrates more noticeably while the app is open.
• The complication now shows exactly the same time as the app, to the minute, and its ring fills up just like in the app.
• Fixed: the remaining time on the watch face could stop updating after a few hours.
• The button is now simply called "End", which also fits the eating window.
• Minor layout and translation improvements.
