■ Assign any sound you like In edit mode you can assign any sound to any button. The picker is three tiers, category -> pack -> variation (fast / short / long / single, etc.), shown with OtoLogic's official names. Every sound can be previewed, even while locked. Build your own sound board.

■ Free vs Pro The free version includes 8 essential sounds (correct, wrong, question, buzz-in, results) and 4 buttons. Upgrade to Pro with a single one-time purchase to unlock all 79 sound effects and up to 8 buttons, and remove ads (one purchase only, restore supported after switching devices).

■ Japanese / English UI Switch the display language between Japanese and English inside the app.

■ Fully offline, and about ads All sound effects are bundled in the app, so playback needs no connection. The free version shows a banner ad at the bottom; Pro turns it off.
