i am playing around with some Sonoff S20 sockets and was searching for an Android App, but i have not found one (maybe i was to dumb to find one).
Because of that i built a simple on/off-app for up to 4 Sonoff S20 sockets. (if you need more, just say it)
Please don't be so hard, i built it with the MIT App Inventor.

Yeah, i know, the Layout is Crap, but it works.

Maybe you can give me some Feedback
