About this app
FastZero is a private, local-first fasting timer built for people who want to take control of their eating windows without handing over their data. No account. No cloud sync. No nonsense.
⏱️ SMART FASTING TIMER
Choose from popular plans like 16:8, 18:6, 20:4, and OMAD — or set a custom duration up to 120 hours. Start by duration or target end time.
💧 DAILY WATER TRACKER
Log your water intake alongside every fast. Your hydration data lives in your fasting history automatically.
📊 INSIGHTS & STATS
Check-in averages, water trends, and fasting history. Pro users unlock the full year of data.
🏅 18 ACHIEVEMENT BADGES
Earn badges for milestones like your first fast, longest fast, and consistency goals. Badges never reset.
📝 JOURNAL
Document your journey with private notes — tied to your fasting history, never uploaded anywhere.
💾 BACKUP & RESTORE
Save a backup file of your entire fasting history wherever you want — your files, your cloud, your choice. Restore anytime by picking the file. No account, no middleman.
🔒 TRULY PRIVATE
Your data never leaves your device. Ever. No account required. No sign-up. No tracking.
