Know exactly when you can eat next.
WhenCanIEat is a simple countdown for your eating window. Pick a schedule, start your fast, and get a clear answer the moment you open the app. No food logging. No calorie counting. No AI coach telling you what to do.
Your first 2 fasts are free, full app included. Then $0.99 a month or $9.99 a year, cancel anytime, no surprise hikes.
Built on two rules we don't bend
Everything about the app follows from these. If a feature would break either one, we don't ship it.
Honest pricing
Download the app and try it free. Your first 2 fasts include the full app, nothing locked. After that, keep going for a fair, flat price, no tiers that creep up and no surprise renewal at a higher number than you agreed to.
