Don’t buy
Purchased the premium version and never received the additional stuff. Adds never went away.
Response from developer
Hello! Sorry to hear about the issue. I have not encountered this error with other customers, but I am looking into it as we speak. In the meantime, you can refund your purchase by visiting https://support.apple.com/itunes. Also, if you like a coupon to get the in-app purchases for free, please email me at akhader3035@gmail.com, as an apology for the inconvenience. Thank you!
