★★★★★ Lots of bugs related subscriptions and offline data.
★★★★★ In addition the English translations are often not correct - wish I had not wasted money on this…..

★★★★★ The whole chapter of the app in “Theory” dedicated to grammar is simply disappeared.
★★★★★ It has gone downhill (with probably AI usage, great, make it garbage thanks to AI).
★★★★★ The app wrongly decided I didn't have a premium membership and deleted my data.

★★★★★ A terrible app full of generative AI garbage and ads to buy even more AI garbage.
★★★★★ I was doing my route thingy and the app thought it's more important to push an ad than to show me my mistakes. After that I couldn't look at my results and just could continue learning. How can I improve myself when…

★★★★★ How can I improve myself when it's more important to push a 2 minute ad, than showing me what I did wrong?
★★★★★ Seems like low quality AI generated content with low effort prompt restraints.
2 of the 1 and 2 star reviews.
★★★★★ Often times using the “explain” to explain an answer is so hard to expand the box to even see it, it's easy to skip the last answer of quizzes (no confirmation if you want to continue) so you end up missing that answer…
★★★★★ The popup says to download the dictionary data for offline use, however in the donload section there is no option to download the dictionary.
Nothing stands out.
3 of the 4 and 5 star reviews.
★★★★★ Both the paid and free version of this app are great and really are good ways to study as a hobby or another way to practice for your classes.
★★★★★ Overall it's actually worth it as a helper for just practicing reading comprehension passages.
★★★★★ I haven't bought the app and a lot of stuff isn't available in the free version, but the theory section is really well done and more thorough than a lot of other apps.
2 of the 4 and 5 star reviews.
★★★★★ It is easy to use and has everything I need for the review.
★★★★★ The app is easy to use and because it's a iOS app it is easy to carry thousands of test questions without the worry loading track of your progress.
2 of the 4 and 5 star reviews.
★★★★★ Knowing kanji is also useful.
★★★★★ Generally speaking this app is useful and very convenient while you have pieces of time, instead of watching Tiktok, you can practicing language!

A terrible app full of generative AI garbage and ads to buy even more AI garbage. Do not recommend.
This app constantly has certain features that don’t work. The grammar section has been unaccessible to me work months now.
I’m sure it’s very helpful to pass the test but this app will NOT help you learn the language. It is a test prep app not a language learning app. You have to know Japanese to properly use it. It also is not very intuitive and its feedback to the test questions can be confusing.
App asks to be updated almost every day. Really annoying and feels invasive.
I was doing my route thingy and the app thought it’s more important to push an ad than to show me my mistakes. After that I couldn’t look at my results and just could continue learning. How can I improve myself when it’s more important to push a 2 minute ad, than showing me what I did wrong?
I love the iPhone App and I find it’s pretty good on the Mac as well. Mostly because the extra size is very handy. I have a lifetime membership. So I can’t say anything to the bugs about that. But they did make it easier to change your subscriptions if you changed devices a lot.
