Clik Interactive recently launched their mobile app named Clik for Apple iOS and Google Android devices.
The app showcases a cool remote control technology. It is currently focused on playing YouTube videos on any device with a browser.
The app requires you to load clikthis.com website on the browser of the display you want to use. The website would load a QR code that you scan using the app.
Once the code is authenticated, it would start the app. The browser on the display would run the videos that you can control from your phone. The app also has a multi-user mode which allow multiple users to control the same display!
It is a pretty cool demonstration of using your smartphone as a remote for your computer. Google in fact had a similar app for YouTube.
