An intermittent fasting tracker built around one idea the category usually skips: knowing when not to fast. The timer keeps counting correctly even if the phone was off for two days, the body-stage timeline says what is a general pattern rather than a promise, and the screening questions come before a plan is suggested, not after the subscription.
Nothing counts down in the background. The app stores the moment you started and works out the elapsed time on every render, so closing the app, rebooting, changing time zone or losing battery for a day leaves the fast exactly where it should be.
A timeline of what the literature associates with each stretch of a fast — glycogen, fat metabolism, autophagy — carrying the caveat that these are general patterns, not measurements taken from you. No disease claims, ever.
Pregnancy, breastfeeding, diabetes on medication, a history of eating disorders and other contraindications are asked up front. A flagged answer withholds the plan suggestion, and an eating-disorder history switches calorie and food logging off entirely.
16:8, 18:6, 20:4, one-meal days and custom windows — but nothing past a 20-hour eating-window ceiling, and anything over 18 hours needs a month of history first. A goal weight that would take you under a BMI of 18.5 is refused.
Water with your own glass size, a hunger journal for the hard hours, meals and weight in the same place — all of it optional, none of it nagging.
Weight trend, completed and broken fasts, streaks and averages drawn natively for smooth scrolling, in kilograms or pounds.
Weight and steps read from and written to Android's Health Connect — one source of truth on the phone, and permission you grant per data type. Google Fit is not used.
Put one to four readings on the home screen — fast timer, current stage, water, weight, steps or streak. A metric with no reading disappears from the widget instead of showing a fake zero.
Eating-window recipes and explainer articles come from our server, so the library grows without you installing anything. Every health article carries its disclaimer.
Point the camera at a plate or a barcode to log it. Optional, and separate from the rest of the app — it is the only part that costs anything to run.
English, Turkish, German, Spanish, French, Italian, Brazilian Portuguese and Arabic, with right-to-left layout. Units and dates follow the language, not the other way round.
No advertising SDKs, no 50-screen onboarding, no countdown discounts and no cancel maze. The final release is one payment; the scanner is the only subscription.
This build is for 64-bit phones (arm64), which covers essentially every Android device sold in the last several years. It is a test build: store billing is not wired in yet, so nothing can be purchased and nothing is charged. There is no iPhone build to download yet — the iOS version goes through the App Store when it ships.
FastTrack is a tracker. It does not diagnose, treat or prevent anything, and it makes no weight-loss promises or timelines. Talk to a doctor before changing how you eat — especially if you take medication.
A birth year under 18 blocks the app, with no override and no remote switch. Fasting guidance for a growing body is not a call we are qualified to make.
If you report a history of one, calorie and food-logging features stay off and no fasting plan is proposed. The app does not try to talk you out of the answer.
A broken fast is recorded as a fact, not a failure. There are no streak-shaming notifications and no review prompt after a fast you did not finish.
Fasts, weight, water, meals and the onboarding answers are stored in a database on the device. Nothing is published, shared or shown to anyone else — there is no social feed.
The app fetches recipes and articles from our server, and — if you use it — sends the photo you scan to have the meal recognised. No advertising or analytics SDKs are bundled.
Access is granted by you, per data type, in Android's own permission screen, and can be revoked there at any time. Health data is not sent to our server.
You can use the tracker without signing up. An account exists only to carry your data to a second device if you ask for it.
