What's New in LadyOne
1.4.1
September 14, 2026
This update only fixes a few things. FIXED • If you'd marked your period as ended and it started again, the app now gets it right. • Restoring a backup no longer creates duplicate days. • One very short cycle no longer throws off your predictions. • Period days no longer count as PMS symptoms. • The evening reminder no longer says the wrong thing while you're late. • When the day changes, Today updates on its own. • The widget no longer goes blank, and "Delete all data" clears it too.
