About fast_ Intermittent Fasting
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 • Next-meal coach — set a calorie goal and see what to aim for at your next meal • Smart meal ideas matched to your goal and diet style • Eating out? Snap a menu or name the restaurant for dish picks that fit your goal • Weather-smart hydration — your water goal rises on hot days, with heat-safety tips • $9.99/month or $59.99/year (save 50%) Built for people who want something simple, that works, and that won't punish you if you skip a month.

What’s new
Version 1.2.0 · Updated October 28, 2026
• Home Screen and Lock Screen widget: see how long since you last ate and your fasting stage at a glance. • A live fasting timer on your Lock Screen and in the Dynamic Island. It shows on your Apple Watch too. • Made for big screens: foldables and iPad now get a roomier two-column layout. • Water goal adjusts for hot days on your phone. Only approximate location is used and it's never saved. (Pro) • Lost track of time? If your timer runs past 24 hours, you can fix when you last ate or start fresh. • Fixes: content no longer hides under notches or the Dynamic Island, and other polish.
