Improved stability when using Undo or Redo immediately after drawing. Added safeguards to reduce a rare issue where the app could quit unexpectedly. In Circle to Solve, you can now check the estimated AI Balance usage before running it. Updated the AI Balance pack usage estimates to better reflect actual usage.

Improved the display of Sticky Note Marker. Fixed an issue where the line could briefly flicker when you finished writing, or be finalized in a shape different from how it looked while drawing.

Updated the AI usage display. We adjusted the estimated usage for practice set generation and AI Summary so the estimates better reflect the content being used. AI Balance pack estimates are also easier to understand, now shown as runs, pages, and character counts.

[Important] We added a system that automatically sends diagnostic data when an issue occurs. The data sent does not include personal information such as note contents, subject names, attachments, images, PDFs, or recording contents. AI balance is managed with an identifier used to verify purchases and balance. This identifier does not contain directly identifying information such as your name, email address, Apple ID, or note contents. [New Features and Improvements] • Added recording • Restored Circle to Solve • Added items for purchasing additional AI balance • Added the ruler tool • Added the ability to move a selected area • Added subject reordering on the Home screen • Added notebook reordering in the notebook list • Fully redesigned the Memorization Marker so it can be used like sticky notes
