Has some potential, but the daily exercises have some inaccuracies that shouldn’t be there and the vocab training with kanji acts very strangely. Some cards have just a kanji and no associated task or prompt. The English translations are off and the voice readings are also frequently different than what’s written. And some sentences don’t make sense in Japanese or English. I also get annoyed by constantly being rated at 80% in pronunciation when my individual scores during the test are above 90%. I’m glad I only got a month subscription. Going back to Bunpo and Wanikani.
I was happy to try the app for a bit and it was working fine but now whenever I open it, it hangs on the kanji loading page. I deleted the app and reinstalled, same issues. Consistent across my iPhone and iPad. It’s a shame.
The app has a clean interface making you think it’s easy to use but far from it. If you want to just use it as a review before you dive into your exact it’s tedious since it makes you record the word without the ability to just automatically swipe and if you skip it makes it seem like you don’t know the word. There’s no easy access to review JLPT material but rather everything is scattered across decks in one location. Organization feels sloppy despite the clean looking interface. Feels like a trick
