OneFeast

Track your daily fast with a clean timer, fasting-stage insights, smart alerts, streaks, and private iCloud sync. No account, no ads - your data stays yours.

OneFeast makes One Meal A Day (OMAD) and intermittent fasting simple. Start a timer with one tap, watch your body move through each fasting stage, and build the streak that keeps you consistent.

WHY ONEFEAST • Clean, always-accurate fasting timer — see exactly how long you've been fasting and how long since your last meal. • Science-based fasting stages — follow your body from digestion to deep ketosis, and learn what's happening at each step. • Smart meal tags — tag your last meal and activity so the stage timeline matches your real metabolism, not a generic clock. • Stage notifications — get a heads-up when you reach Metabolic Switch or Ketogenesis Rising. Pick exactly which alerts you want, or none at all. • History, stats & streaks — every fast is logged with milestones and streaks to keep you motivated. • Private iCloud sync — your data syncs across your devices through your own iCloud and comes back if you reinstall.

PRIVATE BY DESIGN No account. No analytics. No ads. Your fasting data lives on your device and your personal iCloud — we never see it. Export a full backup anytime.

OneFeast is built for people who eat once a day and want a beautiful, focused tool for tracking.

OneFeast is for tracking and motivation, not medical advice. Fasting isn't right for everyone — if you have a medical condition, are pregnant, or take medication, talk to a healthcare professional before changing your eating pattern.
