I used to love this app but as of the update it crashes more and the some of the kana show up bigger than the interface on the writing test, making it impossible to test them.
Also, the new speed test where the romanization is given and you have to pick the corressponding kana is MUCH less effective then the previous speed tests where the kana was given and the romanization was picked.
Please fix this app and I will rate it 5 stars again
