Extremely disappointing app. If ever you switch phones your credits will not transfer over. Twice this has happened to me. Between both times I have lost a total of $20.00 worth of credits. Unacceptable. The developer hardly speaks a lick of English-so good luck receiving a refund on your lost credits. It wont happen.
