Hiragana only

First this application you a few cards only。then as you study you are able to get more points。 I had many points and other cards were opening for free. Then there was an updated version of this application in my iPhone store I pressed on the application the version updated I guess and I lost all my points and all the cards that I opened it was really disappointing and frustrating even writing this review seems difficult the spacer bar wont go back-and-forth I want to erase some of the stars I wrote but it wont even let me do that The points that you are given open new cards but after some days suddenly again all my cards disappeared and it started from zero again once again super frustrating
