Best intermittent fasting apps in 2026
BodyFast gives the most for free: over 10 fasting plans such as 16:8 and 5:2, a fasting timer with reminders, weight and water tracking; a weekly coach plan is paid. Zero tracks fasts with timers and streaks, with photo meal logging in Zero Plus. Fastic pairs fasting with nutrition, with extras in Fastic Plus.
How we picked: a fasting app has to time your fast and remind you, and the good ones track water and weight too. We checked each app’s own store description for what is free and what is paid. This is not medical advice: if you have a health condition, talk to your doctor before fasting.
