What's New in Moonfast
1.7
September 1, 2026
• History now shows how you felt. The feelings and notes you leave when a fast ends are collected in one place — tap a feeling to see just those fasts. • Your longest fast now carries the date it happened. • Ending a fast no longer risks losing what you wrote. The reflection sheet stays put while you're typing, and tells you what was saved. • Stage notifications are quiet now. Only reaching your goal makes a sound, so an overnight fast won't wake you. Fixes • "End fast" and "Log water" on the Lock Screen now work while your phone is locked. • A finished streak clears itself from the Home Screen widget instead of waiting for you to open the app. • Two fasts started on the same day are charted correctly. • Editing a fast can no longer create overlapping entries. • Importing a backup restores your reminders along with your data. • A fasted day older than 30 days is no longer described as empty.
