What’s new
Version 3.5 · Updated September 25, 2026
3.5 Bold new look — a more vivid palette (deeper leaf greens in light mode, electric lime in dark mode, amber for goals reached) across the app, widgets, Live Activity and Apple Watch Liquid Glass — cards and primary buttons use the system glass material on iOS 26 and later (earlier iOS versions keep the translucent style) Slimmer Dynamic Island — the Live Activity countdown no longer stretches the island; past the target it shows a checkmark Custom fast length — long-press Start Fast to pick any length from 4 to 72 hours Apple Watch sync — fasts started or ended on the watch keep the watch's times even if the iPhone was out of reach; duplicate or stale watch actions are ignored; much less battery use from syncing Smarter notifications — reminders follow start-time and target edits and fasts started on other devices; the goal alert moves to 7am instead of being dropped in quiet hours; the daily "start your fast" reminder pauses while fasting Widgets — keep showing your fast after you pass your goal; fasting phases now match the app for every plan length Goals & stats — goals are marked complete when reached; streak goals only count days after the goal was created; streaks use the same day as the calendar heatmap Data fixes — no more duplicate plans across iCloud devices; editing a past fast can't produce negative or future times Fixes — "You're So Close" prompt in the last 15 minutes, milestone haptics no longer repeat when reopening the app, Live Activity no longer resets to 0% when reopening the app
