### 5/5 — Very Helpful!!

*2026-09-28*

Very helpful app ..my screentime went down significantly and I am learning new words everyday !!!

### 5/5 — Makes vocabulary easy to learn

*2026-09-16*

This app makes it very easy to stay on top of vocabulary. In fact it makes it impossible not to learn. I’ve also noticed during my time using it that the creators are actively improving that app.

### 5/5 — Amazing app and haven’t looked back.

*2026-09-02*

Not only has this cut my doom scrolling down dramatically, it’s helped my vocab kanji recognition immensely. Fantastic app 10/10

**Developer response:** Thank you - this is exactly the combo I was hoping for: less scrolling, more kanji. Really glad it’s working for you. If there’s anything you’d want the app to do better, please use the feedback email in the app.

### 5/5 — So far really good

*2026-04-14*

Ive currently only gotten like teo words learnt but im also extremely early in learning! The creator had actually talked to me to help make it down grade to IOS 18 so I was able to use it, the only issue ive had so far is that when your selecting apps to block the menu will glitch and you have to reselect everything again, I had to reselect like 6 times because it kept resetting but from what I can see is that it just struggles to keep multi the folders open at once or something? But regardless of that, its been very helpful and I wouldnt say that makes it any less than a 5 star :]

**Developer response:** Thank you for the detailed feedback🙏
The app selector bug fix is in progress. Glad we got iOS 18 working for you!
