Store description excerpt
Practice flash anzan on your own—fast rounds, clear feedback, no clutter. Pick digits, how many numbers, and how long each stays on screen, then tap Start. Numbers appear one by one. After the last one, enter a single total to score. Correct and incorrect answers use marks and sound, and a session score stays while the app is open. Cancel mid-flash and that round is not counted. Closing the app clears the score. No accounts, no network, no purchases. Works on iPhone and iPad. The UI follows the device language (English / Japanese).
