Timer, Stages, Weight & Diet
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
NEW: weekly protocol scheduler. Plan 16:8, 18:6, OMAD or your own window. Live stage ring shows ketosis & autophagy. Private — your fasts stay on your iPhone.
Fazting is a beautiful, local-first intermittent fasting tracker built for people who care about their data and their time. Start a fast in two taps. Watch your body move through the fasting stages in real time. Keep your weight, photos, and notes on your iPhone, not on someone's server.
WHY FAZTING
• 100% on-device — no account, no cloud, no tracking. Your fasting log, weight, and photos stay on your iPhone.
• Designed around the fasting clock — a live stage ring shows where you are in autophagy, ketosis, and growth-hormone elevation, computed from your start time alone.
• Built for daily use — start a fast in two taps, end it in one. The timer keeps perfect time across reboots, time-zone changes, and DST.
PROTOCOLS
• Free: 12:12, 14:10, 16:8, 18:6 — the most popular IF schedules
• Premium: 20:4, OMAD, 5:2, Eat-Stop-Eat, Alternate-Day, Warrior, plus a custom protocol builder for any window you want
• Weekly scheduler — assign a different protocol to each weekday so weekends can breathe
TRACK MORE THAN FASTS
• Weight log with charts, moving averages, and goal projection
• Body measurements: waist, hips, chest, arms, thighs, body fat % — premium
• Progress photos attached to weight entries — premium
• Achievements that mark fasting milestones — first 16h, first 24h, 100h, 1000h, monthly streaks
INSIGHTS
