This app is fantastic and does what other apps cannot on the iPhone. Its data seems to be accurate, and it remains an invaluable tool for diagnostics.
The issue is the in app purchase. Even though I paid to have ads removed, they still appear about 50% of the time. It is very frustrating. This problem persists even after deleting the app and then restoring purchases.
