What's New in Sleep Tracker AI Coach
1.1
August 30, 2026
Your sleep schedule now drives tonight's plan. - Set your bedtime and wake time in the You tab and Today follows straight away. "In bed by" matches the bedtime you chose, and moves earlier only when sleep debt calls for it. - Your wind-down window and bedtime reminder now move with the schedule instead of staying where onboarding left them. - The watch complication and the home screen widget pick up the new plan too. - Fixed a sign-in issue that could leave you stuck on the welcome screen, plus clearer sign-in errors and translation polish throughout.
