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 and never leaves your device. No analytics, no tracking, no servers. Requests go directly from your phone to WaniKani.

Requires a free WaniKani account and API key.
