Smouldering Durtles1.2.8

Use Smouldering Durtles to work through WaniKani lessons and reviews from an Android device, with extra tools for studying kanji and vocabulary. It serves learners who want a dedicated companion to WaniKani, the kanji-learning platform created by Tofugu, while keeping review work available beyond an internet connection.

Advanced search helps you find a specific kanji or vocabulary item quickly, and self-study quizzes provide additional practice outside the standard review flow. Offline reviews let you continue testing your knowledge when connectivity is unavailable, then maintain your study routine without interruption. Multiple themes change the app’s appearance, giving you different visual options for regular lessons or extended study sessions. These features make it useful for daily WaniKani practice, targeted revision, and checking individual items while studying.

Smouldering Durtles runs on Android 5.0 or later and uses a Universal architecture. An active WaniKani account is required to access the app’s full capabilities, and the app is open-source. It is an independent project, not officially supported or endorsed by Tofugu.
