Fasting Timer for iPhone
Intermittent-fasting timer with HealthKit history and a clean stop-go button — for $19.99 once instead of Zero’s $80-per-year coaching subscription you’ll never actually use.
Planned Swarmval app. Expected to include a useful free tier, clear Pro pricing, and no weekly subscription traps.

Features
Built around the work people actually need to finish.
One-tap start/stop
Big button. Tap to start a fast, tap again to break it. The timer counts. Your fasting window is logged to HealthKit when you stop.
Common protocols built in
16:8, 18:6, 20:4, OMAD, 24h, custom. Pick once and the goal bar shows your progress against it.
HealthKit history
Past fasts are logged to HealthKit so they live alongside your other health data and survive app deletion. Other apps that read HealthKit (Apple Health, etc.) can see them.
Lock Screen Live Activity
Active fast shows on the Lock Screen with elapsed time and goal progress. No need to open the app to check.
Weekly + monthly graphs
See how often you actually hit your protocol. No streak-shaming, but the data is there if you want to look.
No coaching upsell
Zero and Fastic push expensive coaching subscriptions. Fasting Timer ships the timer + history. That is the product.

Read privacy policy FAQ
Is intermittent fasting safe? +
For most healthy adults, yes — 16:8 fasting is well-studied. Pregnant women, people with diabetes, people with a history of eating disorders, and people on certain medications should not fast without consulting a doctor. This app is a timer, not medical advice.
How is this different from Zero? +
Zero ($80/year) bundles a fasting timer with a meditation/coaching subscription you’re paying for whether you use it or not. Fasting Timer ($19.99 lifetime) is just the timer and the history. Use Apple Fitness+ or any other app for coaching if you want it.
Does my fasting data sync across devices? +
Via HealthKit — yes. Apple iCloud syncs HealthKit data across your iPhone, iPad, and Apple Watch. The app itself has no cloud; it relies on Apple’s HealthKit sync.
Will the timer keep running if I close the app? +
Yes. The fasting timer is timestamp-based, not a foreground process. Close the app, restart your phone, the elapsed time is still accurate when you reopen.
