Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Fast! makes intermittent fasting simple and social. Start a timer, watch your body move through each fasting phase — from blood-sugar stabilizing to fat-burning, ketosis, and autophagy — and log how you feel along the way.
• Clean, real-time fasting timer with science-backed milestone markers
• Track your history, streaks, and progress over time
• Connect 1-to-1 with a friend or create a group to fast together and see each other's live progress
• Send quick encouragement to keep each other on track
• Private by design — your data is yours
Whether you do 16:8, 18:6, OMAD, or your own schedule, Fast! helps you stay consistent.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Notifications now actually arrive.
• A friend's message reaches your phone instead of waiting silently in the app
• Turn nudges on from the friends section — and if you turned them off, the card now takes you to Settings
• See your year as a grid, and open any day to read back what you wrote
• Log drinks with a plus and a minus rather than a hidden gesture
• Friends' progress bars are back on the home screen when you're not fasting
Thanks for fasting with us.
