The technology used is quite simple. One is required to install the app on their Android phone. Then visit roamingswitch.com on their desktop(s). Download the file from there and generate a one-time pairing key. Once the pairing key is inserted in the app, one can switch off their computer(s) remotely. The app was launched in the wake of Earth Day and was promoted amongst NGOs first to spread the word in the right networks. An outdoor and social media campaign was then undertaken to promote the app further amongst organisations and individuals.

Within ten days of its launch visitors from over 25 countries visited roamingswitch.com.

Media widely hailed Roaming Switch as an effective energy saving solution. The Power Ministry under Govt Of India is testing the app for government and quasi government companies. Many energy conservation activists and alternate energy corporations have come forward to promote Roaming Switch amongst opinion leaders and policymakers.
