Waste of time and money!!!

I gave it 2 stars because my phone was barely warm but this app stinks its not worth the money it should be free. Im recommending to the app owners that they should make improvements to this app and make it free. I think if it worked then it would be wourth the pay but It doesnt and I gave it time, 35minutes to be presice.
