A clean intermittent-fasting tracker — eating windows, hunger calibration, honest energy logging, and the fence around the practice that prevents IF from sliding into food obsession.
Get notifiedSee featuresThe features that make Intermittent Fasting Tracker useful day-to-day.
Eating-window logging that's quick — start, end, what you ate, how it felt. No moralising; the data is for you, not for an algorithm to score you.
Hunger calibration — distinguishing real hunger from boredom-eating, hydration confusion, cortisol-driven cravings. The skill that makes IF sustainable.
Energy and sleep notes alongside the windows — the patterns that surface across weeks, the signs that the protocol is or isn't serving your body.
Honest off-day handling — when life means an off-window day, the tracker absorbs it without guilt. Sustainability over streak-defence.
Built for the people who'll actually use it, not for tick-box procurement.
Designed for daily use, not enterprise checkbox compliance. The features that matter, none of the ones that don't.
Hosted on our own servers in Estonia. No US-jurisdiction tracking, no third-party analytics, no data sales.
