New: Body Timeline — tap the vessel to see a single fast end to end, with every stage counted from your own history. New: the fast now runs on your lock screen and in the Dynamic Island, with widgets in every size. New: "Dark Mode" across the app, following your device or pinned in Settings. New: Longer fasts now have stages out to 72 hours. Plus fixes for completed fasts being marked as ended early, long fasts missing from the calendar, step counts not resetting at midnight, streaks not counting, and weight forecasts projecting from data that wasn't yours.

Zero Fast has been rebuilt from the ground up. A new look across every screen — a calmer timer, a clearer history, and a "You" tab that actually tells you something. Choosing a fasting rhythm now shows you the window you're committing to before you start, and finishing a fast gives you the record of it rather than a pat on the back. NEW THIS RELEASE: • Progress photos you can compare side by side • A guided journal that asks better questions • A forecast for when you'll reach your goal — with an honest confidence range • Weekly plans built from your own fasting history
