User reviews

Useless!!!

It’s about 115 degrees outside (typical desert summer). I was concerned about my phone’s internal temperature. This app said that it was 32 degrees Fahrenheit. I doubt that. It also said that my device wasn’t connected. I allowed all of the access that it asked for. Still didn’t work. There’s no way to check or change settings. I don’t understand why this useless application is in the App Store.
