For all of you, who ask themselves, what happened to MoneyStats and why it is not available in the AppStore anymore, here is the solution. After v2.1 was released it had quite a good start. Sadly a critical (and really dumb error) was included. Instead of shipping the initial data comprising some demo account and category information, the app delivered the complete testing data with several thousands of entries with no use to anyone. As it is tediuos to delete all entries manually I made a hard decision and pulled the app from the AppStore until release v2.1.1 is reviewed by Apple.
After a while MoneyStats v2.1 is being in review by Apple. It took a little longer than expected, but the current version has some unplanned improvements especially from user feedback.
