About this app

Fasting, made simple — and built so you'll actually keep it up.

Most fasting apps are cluttered, naggy, and expensive. fast_ is the opposite: open it, log when you eat, and your fasts record and tier themselves — Micro, Mini, Short, Fast, Extended, Deep. No start/stop fiddling, no guilt, no walls.

FREE, FOREVER
• Auto fasts — just tap "I ate" and the app handles the timing
• A clean live timer showing your current tier
• Log meals with calories + macros, fully searchable
• Water tracking with a daily goal
• Weigh-ins with a trend chart
• Share a meal with friends or family using a quick code
• Works offline — log on the go and it syncs when you're back online
• Real stats, streaks, and a 7-day chart
• 7 themes, from neon synthwave to clean light, plus a colorblind-friendly palette
• Hide any feature you don't use — make it as minimal as you want

GO PRO — OPTIONAL
• Snap a photo of your plate and the calories + macros fill themselves in
• Or just type a meal and it gets estimated for you

Built for people who want something simple, that works, and that won't punish you if you skip a month. No ads. Your data stays yours — delete it whenever you want.

Start your next fast in two taps.
