Disgusted.

Downloaded the app, used it for a few days then paid 5.79 to upgrade to premium. Today the app froze repeatedly forcing me to delete it and then reload it to the iPad trying to fix the freezing issue. Now my 5.79 is gone as it is asking me to pay for the premium version again.
Wont be getting another dime from me. Utter crap.
