PROTO is an real time electronic circuit simulator which means you are able to setup a circuit with varoius components and simulate behaviour of the electronic circuit.
During simulation you can check voltages, currents and many other variables. Check signals on multichannel oscilioscope and tune your circuit in real time!

* PLEASE KEEP IN MIND THAT THIS APP IS IN ALPHA STAGE :) *
* You can report an issue or make component request at https://github.com/Proto-App/Proto-Android/issues *
