An app that lets the android phone work as a multi-meter, it is based on the idea that the only analog input socket that android devices has is the headphone jack, the app uses the current/ voltage that is input from the mic wire of a pre-cut headphone to measure the voltage/ current/ or resistance, more explanation can be found in the app .
