Waiting for update with bigger/adjustible fonts

This app looks really promising, but currently, when using it on my 12.9 iPad, much of the text is too small for me to enjoy using it, and the contrast isn’t high enough with some instances of dark red Japanese characters against a dark background. The settings section indicates that a font-size update is coming, so I’m looking forward to that.

Liking it a lot so far

The FSRS model got me through engineering school, so I’m already liking in with this app. Seems to be a great tool so far. The UI is simple and intuitive.

My only complaint is the lack of text to speech at the pro tier. I know all of my hiragana and katakana, but I’m struggling with the lack of pronunciation.

The expert tier is just too expensive, in my opinion, for what it offers. I really with there was an in between tier at like $75-$85 that included the text to speech (or if it was just included in the Pro tier).

Love this app. Makes learning fun!

The best Japanese language learning app I've used. It makes learning vocabulary & grammar feel like a game instead of school work. The spaced repetition is great! It doesn't baby you with weird gamification nonsense, just hopes you get fluent.
