ChuuiCroc

Burned out on checking WaniKani manually? ChuuiCroc runs quietly in the background and taps you on the shoulder the moment your reviews or lessons are ready — so you can strike while the SRS iron is hot.

Simple setup

Enter your WaniKani API key once and you're done. No account, no sign-up, no ads.

Smart notifications

ChuuiCroc tracks which items are available, not just how many. That means no duplicate alerts when you clear your queue and new items unlock at the same count — you'll only be notified when something actually changes.

Stays out of your way

Set a quiet-hours schedule with the interactive hour grid so notifications never interrupt sleep or work. Choose how often the app checks — every hour, every two hours, or every four.

Privacy first

Your API key is stored in the Android Keystore. A lightweight push server checks WaniKani on your behalf and sends notifications — no analytics, no tracking, no ads. Your data is automatically deleted if you unregister or stop using the app for 30 days.

Requires a free WaniKani account and API key.
