What's new

Version 2.7.0 · 5 May 2026 · 5 months ago

Smart Study Reminders Turn on optional reminders and Vessel Lights will bring you back only when there is something useful to practise: an unfinished exam, personal practice, or mistakes to review. Respectful Timing Reminders use quiet hours and weekly caps, so notifications stay focused and easy to control. Reliability Fixes Improved background sync for reminder profiles and fixed a rare secure-storage crash during start-up.
