The app doesn‘t work at all and no refund
Unfortunately the premium edition is full of bugs and is not possible to use at all. The buttons are not responsive and the app keeps freezing. What a shame! I asked the developer for help, he suggested rebooting and reinstalling, which I repeatedy did. At that moment it was already to late for a refund, even for this absolutely faulty app. I am completely disappointed and won‘t recommend anyone purchasing this app.
