Update review: Critical error fixed
Edit: I have upgraded my review to four stars due to the creator’s explanation: There was a critical error in the versions 1.16 and 1.17 which caused that behavior. This is fixed now with version 1.18. Old review: I had to turn my iPad off and back on so that I could immediately delete this app! When I downloaded the app, immediately a popup came up that wanted me to buy the Pro version (believe $1.99). I COULD NOT eliminate the popup by brushing up to do away with it and continue with my iPad use. Nothing worked to brush away the popup for the Pro purchase, so I hard reset my iPad and immediately deleted the basic app. Beware!
