The GainSpan Smartplug application works in conjunction with Gainspan SoC based Smartplugs and displays various power measurements as obtained from the Power Measurement IC used. It also allows the load to switched on/off. In Chart mode, it graphs the various parameters as they change with time.

GainSpan Smartplug displays the following power measurement parameters:

* Current
* Voltage
* Power
* Power Factor
* Frequency
* Cumulative Energy (if the IC supports this feature)

In addition, the app allows re-setting the cumulative energy value to zero.
