What's New

Version 2.3

WaniKani Improve works again after the recent change to the WaniKani website. Once you tap the screen during a review session, there will be a short delay before the item goes green and auto-advances to the next item. This is expected and now unavoidable.
Jitai once again will cycle through more than just two fonts.
WaniKani Double Check has been removed. It needs updating as it will otherwise cause disconnection errors once a planned WaniKani site update proceeds in August.
iOS 11 crash fixes.

A Godsend To Have Available


This app has been a godsend, making it possible for me to study when there's been no other effective or functional options for me technology-wise. I typo very often, and sometimes respond with the Japanese reading instead of the English meanings too, both particularly bad the more tired I am... and face it: we're studying Japanese. Tired is our normal state. WaniKani Override script is critical if you want to keep your head above water. This app makes it, Improve (Lightning), and a couple other scripts available, plus offers a handy interface that lets you see how your workload is going to be, and the general status.

*KEEP AN EYE OUT if you're using the scrips on PC/Firefox: the "Override" script on Greasemonkey is abandonware, and is showing signs of having broken again this summer. It should be functional on this app, however.



AlliCrab is a great little app, and effortlessly delivers everything you need for all things Wanikani. I hear what people have said about it only linking to the WK website, but actually the app works best in it's simplicity. It doesn't feel cluttered or cheesy, (and the always-tastefully-brief home screen art will make you wish you had a few seconds longer to feast your eyes on its rich composition.) :-p Add-on scripts definitely enhance the functionality of reviews and lessons. And, with its subtle and timely review reminder messages, Allicrab's really pushed my daily study time up, and has made my reviewing easy and more effective.

Great app!


I love this app! Thank you for putting in so much time and effort and still not charging a nickel!

My two complaints are that the current level time and average level time are always incorrect. For example, I've been on level 4 for maybe 3 or 4 days, and it says I've been this level for 10 days. It says my average level time is 3 days 19 hours, which is impossible.
