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 • Fasting-stage timeline: see exactly when your body enters fat-burning, autophagy, and ketosis • GitHub-style consistency heatmap so you can see your year at a glance • Best day of week, longest fast, completion rate, weight-vs-fasts scatter • Streak tracking with optional streak freezes — premium • CSV / JSON export of everything — premium SMART REMINDERS • Notifications fire at start, midpoint, and end of every fast • Stage-milestone alerts when you enter ketosis or autophagy • Hydration nudges during long fasts • Customizable per protocol — silent during your sleep hours WHAT MAKES FAZTING DIFFERENT • A real stage ring, not a generic countdown — see autophagy and ketosis as they happen • No account, ever — open the app and it works • Lifetime purchase available — pay once and keep premium forever • Designed in a soft, calm visual language so it doesn't feel like another loud fitness app WHO IT'S FOR If you want to lose weight with intermittent fasting, build a 16:8 or OMAD routine, understand the fasting stages your body is in, or simply track your fasts privately without handing your data to another wellness startup — Fazting is built for you. PREMIUM Unlock advanced protocols, body measurements, progress photos, streak freezes, and full data export.
