This is by far the best SRS/handwriting/listening/reading app on the market. HOWEVER. There are severe limitations in freedom - you can only create lists using words from their predefined lists, and updates are incredibly rare and don't add much - major updates are even rarer. Considering how much you have to pay for all of the audio packs, this is pretty crappy on the devs part. Such a shame that an app can do so much so well, and completely screw up everything else.
Great but could be better I've had it for two weeks and used it for 30 hours. So the best drill app I've found so far. But the JLPT vocabulary list needs updating (radio-cassette?) and most importantly, some definitions suck: too long to fit (あんな), archaic/miss the point (e.g. すごい=terrible). But overall a great tool, one I wish I had when I started learning Japanese years ago - thanks to the developer!
The algorithm is not good. For the handwritting same 5 kanji keep coming out again and again even after 300 words learned.
