Improved ad placement and visibility on the free plan. Patient and examination menus now stay clear while selecting records. Also improved ad completion behavior and overall stability.

Improved patient history synchronization and reliability across multiple devices. Older examination records are now preserved during automatic saves, including for patients beyond the first 100 entries. Missing cloud history no longer creates a blank initial visit. Account switching and synchronization are simpler, and iPad startup stability has been improved.

Improved Premium subscription flow, voice input access, and periodontal chart data saving. The clinic voice input signup page is no longer shown to new users.

- Added a notice for iPad users about the new one-screen layout for PPD, Mobility, and PCR. - New iPad users now start with the one-screen layout by default. - Adjusted the Add Patient dialog position so it is easier to use when the keyboard is shown. - Improved patient and inspection data sync reliability, especially with large datasets.

Restored the previous stable iOS behavior from version 1.0.33 to address an issue in version 1.0.37.

- Added manual Firebase save controls and unsaved-change prompts. - Fixed initial startup rendering on iOS. - Improved save icon visibility.
