ARCFAST — INTERMITTENT FASTING TRACKER Track every fast with precision. Arcfast is a clean, focused intermittent fasting tracker built for people who want results, not clutter. TIMER THAT WORKS FOR YOU Start, pause, and resume fasts without losing progress. The ring timer shows remaining or elapsed time at a glance. Tap to toggle modes. 16:8 TO OMAD — YOUR CHOICE Choose from built-in presets (12:12, 14:10, 16:8, 18:6, 20:4, OMAD) or create a custom fasting window. Switch anytime — your history stays intact. WEEKLY SCHEDULE Assign a different preset to each day of the week. Arcfast automatically selects the right protocol on the right day. BUILD STREAKS THAT STICK Daily streak tracking keeps you accountable. Enable streak protection for a built-in grace day — one missed day in seven won't break your momentum. MILESTONE MOMENTS Contextual messages appear throughout your fast — at 4h, 8h, 12h, 16h, and beyond — reminding you what's happening in your body and keeping you going. LOG WEIGHT & SESSION NOTES Record your weight after each fast with automatic Apple Health sync. Add optional notes to capture how each session felt — energy, mood, how long you held out. SMART NOTIFICATIONS Get notified when your fast starts, at your chosen hour checkpoints, when you hit your goal, and 1 hour before your eating window closes. All configurable. DAILY FASTING FACTS A new science-backed fasting fact surfaces every day — covering metabolism, brain health, gut function, history, and more. WEATHER-SMART SUGGESTIONS On hot or humid days, Arcfast suggests a shorter fasting window to reduce heat stress. On cool, high-momentum days, it may suggest stretching your goal. INSIGHTS & ANALYTICS Track your 14-day completion rate, weekly fasting hours, goal-hit rate by preset, and start-time consistency heatmap. Watch your weight trend over time. APPLE HEALTH INTEGRATION Completed fasting sessions are written to Apple Health as Mindful Sessions. Weight entries sync as Body Mass data. EXPORT YOUR DATA Export your full session history as a CSV anytime — it's your data. ARCFAST IS FOR YOU IF: • You practice 16:8, 18:6, OMAD, or any time-restricted eating protocol • You want a clean tracker without social features or bloat • You track weight alongside fasting progress • You want to understand the science behind your fasts, not just the clock No account required. All data stored locally on your device. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
