What's New in Sleep Ledger
1.11.1
June 22, 2026
What's New in v1.11.1 — Your Corrections Count FIXED - Manual sleep entries now take priority. When you add a manual entry for a night that already has Apple Health or AutoSleep data, your correction replaces the automatic data everywhere — your sleep debt, the recovery plan, and CSV export. Until now it only updated the History view, while the original data still counted toward your debt and appeared in exports. - This is especially helpful on nights without Apple Watch, where automatic tracking can be incomplete — your manual entry now gives a more accurate debt balance. Thank you for the feedback that led to this fix. Settings → Contact is the fastest way to reach us.
