Shorter fasts are shown too, instead of disappearing. • Weights and heights can now be entered in kg and cm. • Onboarding is shorter, has Back and Skip, and your first fast starts right away. Body stats are optional. • Fixes: a skipped starting weight no longer records a 0 lb entry that flattened your weight chart; ending a fast no longer cancels your other reminders; the paywall always shows live prices from the App Store. ### 1.3.1 — 2026-07-17 • Every install now starts with a FREE week of Pro — no payment info needed • Adjust a running fast's start and end time — hit Start late?
