Easy to use, but...
Very good!
Lite version only has 5 kana
The good: I like the interface. You can adjust it to practice the kana you want.
The bottom line: this is only worth getting if you're wondering what the paid version is like. Some lite versions of apps have functionality of their own, but this is only good as a preview--not worth downloading if you're looking for a free hiragana practicing app.
