This is a blackboard app designed for memorization through writing. Since the text you write disappears automatically, you can focus entirely on repetitive writing to memorize. The auto-erase feature can also be disabled, making it useful for taking notes or as a communication board. On iPad, memorize side-by-side with other learning apps. Free, no ads and no in-app purchases. How to Use Auto-Erase Mode Tap the icon on the far left to enable the mode where written text disappears automatically. Manual Mode Tap the second icon from the left if you do not want the text to disappear automatically. Tap the trash can icon to clear the screen. Customization You can change the line thickness, line color, background color, and erase time from the menu. There is no in-app save function. If you wish to save your work, please take a screenshot.
