What's New in OneLine
1.5
August 19, 2026
A fix for VoiceOver in the activity map: each day now opens the day it announces. It used to name one date and open the one a week later. If you missed version 1.4, that is the one to look for: you can open any past day and write it in, choosing a photo from your library works again, and a calendar bug that hid the first days of some months is fixed.
