This app is not for beginners! Do not use this if you are trying to learn kana for the first time. The specifications are too demanding and it will only give you a good grade if you write it identical to the calligraphy. Not to mention that is mostly impossible because we are to use our fingers on a non-pressure sensitive screen. The adds are really annoying because they pop up often in full screen when trying to practice. The touch function does not always load in quick enough so I found myself writing nothing on the screen at times. The timer does not help at all when practicing kana; besides, calligraphy is an art that shouldn't be timed anyway. tl;dr Not for beginners. This app is not good for practicing kana.
Best app so far to learn proper strokes for kana...
Good app for learning the kana
Great for learning. Bit strict though
