### 5/5 — Sehr gut

*2025-09-14*

Mega gute App um den Wortschatz zu erweitern. Die N4 bis N1 Pakete sind auch sehr günstig und die App ist einfach super gut!

### 5/5 — Really fun!

*2021-04-17*

I’ve been using this app for quite a long time and first used it on an iPod touch 
Now using it on iPhone 12 and it works perfectly 😊
Really hope to see some updates one day!

### 1/5 — Hopes dashed - immediate letdowns

*2021-03-06, version 1.6.1*

I just bought this app, and I’ve noticed that it has some pretty serious issues. I began a quiz, but the bottom choice (the 4th of 4 in a multiple choice quiz) is cut off, and you only see a thin slice of the very top of that word.

Also, each page of the quiz needs to be centered. Currently, it’s too far to the right. 
   
Each page of the guide needs to be centered. They are currently too far to the right.

The settings page needs to be centered. It’s too far to the right.

The home page seems centered, but there’s somethign at the top-right that seems to need moving over to the left. Right now it appears to be cut off.

I really wanted to just dive right into this app, but with selection in quizzes being cut off, there’s no point in trying right now, until the app receives a thorough revision and update.

### 5/5 — Review

*2019-10-15*

A nice APP for learning Japanese vocabulary.

### 1/5 — Not functional

*2019-09-09*

Only three of the four multiple choice answers show up on my screen, must not be suitable for smaller phone screens. I have an iPhone SE.

### 3/5 — Needs a ‘remove word button’

*2019-03-18, version 1.6.1*

There are a lot of words that I do not want to learn At All so I am a little upset that I don’t have an option to Remove words from the flash card list. That would make this app 5 star.

I  a visual learner, so this helped my with learning kanji really well but the spoken words do not want to stick in my mind compared to learning words with pictures.

### 3/5 — Doesn’t fit on screen

*2018-09-25, version 1.6.1*

I also have an iPhone SE and parts of this app doesn’t fit on my screen. I like this app, however, it’s rather annoying when I can’t select the right answer. I hope this can be fixed in the future.

### 3/5 — Good for vocab

*2018-06-24*

Good study tool for vocab but when using the quiz now, the forth option is cut off from selecting. Maybe it’s only for phones with larger screens? (Have an iPhone SE)

### 3/5 — Great app

*2018-06-10*

I would be prepared to pay for this app, but it doesn’t fit to the screen of my iPhone 7. Please sort it out. This app is fantastic for quizzing myself on vocab!

### 3/5 — Good but desperately needs proofreading

*2018-05-21*

The quizzes are good how those are broken out into 3 types, but there are some rough edges. Several example sentences are unrelated to the study word, and the translation of some words are wrong, eg 生物 = raw food, when it should be living thing. The is no furigana for the examples, so sometimes it’s hard to work out the readings. All these slow or hamper the educational benefits of the app. The app developer could be more responsive to feedback. I still lean on the side of recommending the app for the variety of drills offered, but I really wish it gets a brush up by an expert to improve the educational value.
