What's New in Moonfast

• The ring now says how much longer: "4h 35m to go", right under your goal. • Ending a fast no longer opens a sheet. The card that follows shows what was saved and lets you add a note when you want to. • History reads more clearly: one set of labels, "(next day)" on fasts that cross midnight, and a way back from a feeling filter. • The projected goal date waits for three weigh-ins and says it follows the smoothed trend. • Settings › Apple Health tells you what it can actually know: whether you've been asked, never a "Connected" iOS can't confirm. • Every language reads its own units, and a first streak is no longer plural. • A "Not now" on the notifications page during setup. Fixes • Exports from early versions restore again. • Editing a past fast keeps to the 24-hour limit. • Home Screen widgets and the watch no longer show a streak that may have lapsed. • The Lock Screen "End fast" button asks for a second tap, so a stray touch can't end a long fast — and it works without a dialog the Lock Screen can't show. • A change of accent reaches a running Live Activity.
