Works great if you follow directions – MyPi. Review

Works great if you take the time to read the instructions. Initially I tried running the app without installing the python server. It will not work like that. You have to use python to modify gpio output. The app works by working with a python script that modifies gpio status with the app hotkeys. Since it's meant for a relay, if you use the app without a relay its "Opposite Day". You'll see what I mean if you just try to work with a breadboard straight from the Gpio pins. Awesome app and it's free if you ignore the 5 second ads.
