### 5/5 — great for wanikani

*2026-02-15*

at first you maybe dont need it but after level 10 there are like 100+ reviews coming up a day, it is almost impossible to sit at your computer and do them all - this has made it manageable to power thru them all still and stay on track

### 5/5 — Amazing app

*2022-01-01*

Love the simplicity and ease of use. Probably the best WaniKani app out there. Would be great to have the option to display the custom entries too, but hey it’s already super handy. So thanks for making it!

### 5/5 — A WaniKani app that I didn’t know I needed!

*2021-04-24*

I was a bit disappointed in the WaniKani app offerings currently available, but then found this little gem. The UI is clean and simple and it makes my review sessions go much more quickly/smoothly. I’d like to see a few more options available in the future, such as changing font size and such, but this is a perfect execution on a great app concept!

### 5/5 — Thank you for implementing back to back!

*2020-11-25*

New review: I asked and it was answered! Now that back to back is implemented the app is perfect! This developer is awesome for listening to feedback. It's my go to review app now. The font still can't be changed but it's bigger now and much easier to read! 

Old review: I really love this app! I really can't complain and it works exactly like it says it does. It would be cool if you could change the font size. The only reason I don't use it too often is because I'm used to using scripts/tsurukame where I can do one full review at a time, meaning first and then reading immediately after. I keep revealing meaning when I meant to reveal a reading and vice versa. It's a minor nitpick for an awesome app!

**Developer response:** Thanks for the great feedback!

The back-to-back feature is brought to you by Joy Alice (@joyalicegu on GitHub), so all the credit for that goes to her! Juken is an open source app that's been receiving contributions from amazing developers, and they've been doing about all the work on the recent great features!.

### 5/5 — Best Wanikani Review App

*2020-09-24*

I haven’t had any glitches and the only thing it’s missing is Apple Watch support :( Too bad it’s not possible for this type of app

### 4/5 — Promising, gorgeous looking

*2020-07-16*

I’ve just started with this app and I love the concept. I would love the addition of an indicator of when the next reviews will be available. I find you have to make quite a solid swipe to get the next card too.

### 5/5 — Simple and effective

*2020-06-20*

Does exactly what it says: speeds up and simplifies reviewing while presenting a smooth interface and attractive color palette. 

This app has no frills. Useful additions that wouldn’t overburden the app would be: unlocking lessons, review notifications, and a variety of font options.

**Developer response:** Thanks for the great review! 

I've been spending all my time working on under the hood stability improvements since the launch, but now that's out of the way and I'll have more time to work on enhancements! I created tickets for your feature requests, and will definitely be adding them to the roadmap.
