Kickerfrei foosball table busy

This app is targeted to old Android based phones that you ducktape below your foosball table in the office.

It will periodically report to a web service (such as this: https://github.com/ge-o/istdertischkickerfrei) the accelerometer standard deviation of a reading.

Simply speaking: it will report to a website wether a foosball table is currently being used or not so you don't have to gather your crew just to find the damn thing blocked by some weird people from the HR department :-)
