Spending huge sums of money on a universal remote control might not be a great idea, especially when you own a smartphone. There are plenty of applications available for different operating systems that can turn the smartphone into a universal remote. However, that involves buying a small (and not so expensive) accessory to be paired with the app. Technically, most AV devices still use remote controls that work on infrared light. As smartphones don’t have IR emitters, one has to install an additional IR dongle. For instance, there is a special Tata Sky Mobile access app available for iOS and Android smartphones that turns the phone into a universal remote control for Tata Sky, DVD, TV and amplifier. But it requires an MP3 mobile accessory (` 350) to be connected to the phone’s 3.5 mm jack. Dijit Universal Remote for iOS needs to be paired with Griffin Technology’s Beacon. Re app, RedEye and Peel Universal Remote are some of the other remote options. Search for universal remote apps in iOS App Store and Google Play Store for more such options.
