iPhone
No subscription. No quiz. No AI coach. A beautiful fasting timer with Live Activity, fasting zones, and a lifetime unlock for less than one year of the big apps.
FastTrack is intermittent fasting the honest way. No subscription required, no onboarding quiz, and no AI coach reading your data. Just a beautiful one-tap timer, with a built-in water tracker, that respects your time and your privacy.
WHY FASTTRACK
Most fasting apps hide the basics behind a $70-per-year subscription and a long quiz before you can even start a timer. FastTrack flips that. Buy it once and own it for life, or pick a low weekly or annual plan if you prefer. Everything runs on your device. There is no account and nothing to sign up for.
FAST YOUR WAY
- One-tap timer with a live progress ring
- Every protocol: 16:8, 18:6, 20:4 and OMAD
- Gentle, circadian-friendly presets (12:12 and 14:10) for easing in or fasting alongside GLP-1 medication
- Custom windows up to 24 hours
- Forgot to tap? Edit your start and end times anytime
SEE WHAT FASTING DOES

A MODERN iOS APP

STAY HYDRATED WHILE YOU FAST
- One-tap water logging: 250, 500 or 750 ml (or fl oz), plus custom amounts and undo
- A daily water goal you set, with a progress ring and how much is left
- A hydration streak for every day you hit your goal
- 7-day hydration history at a glance
- Optionally save each drink to Apple Health as dietary water
PRIVATE BY DESIGN
Your fasting data never leaves your device. No account, no tracking, no ads.
FASTING SAFELY
FastTrack is an educational timer, not medical advice, and it never rewards extreme fasts. Fasting is not right for everyone. If you are pregnant, under 18, take medication, or have a history of disordered eating or a health condition, please talk to a clinician first.
This app offers a weekly subscription with a 3-day free trial, and an annual subscription, plus a one-time lifetime purchase. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel subscriptions in your Apple ID Account Settings.
