An application downloadable to a mobile device is provided for facilitating muscle therapy, the applicable programmed and configurable to generate waveform signals, the waveform signals configured to be employed by a power circuit to generate energy, conforming to the signals, to a muscle pad. The application may be combined as a system with a muscle pad electrically interfacing with the downloadable application, as well as a discrete device in electrical communication with the mobile device and the muscle pad. A power circuit and a muscle metric feedback circuit are contemplated as part of embodiments of a system or kit.
