Cross-platform goodness is something you have to appreciate about Google. It's just recently released the Chrome Remote Desktop app for iOS, allowing you to control your PC, Mac or Linux machine from your iPhone or iOS. This is pretty nifty considering a lot of similar remote control apps aren't exactly cheap for the functionality that Google is giving away for free.
All you need to do is download the app and also install the plugin on either a Chromebook or Chrome browser.
Your PC, anywhere
Why this app would be useful? For tech support, of course. Imagine being able to troubleshoot a friend's PC without actually needing to be there. Or your mother's. Or your boss'. You get the drift.
While the app is not quite as powerful or as feature-rich as similar apps, you can't beat the great price of free. The cross-platform capability and the ability to troubleshoot via Google Hangouts make the experience far less of a hassle as compared to the need to install various other software.
The downside of this? Is not being able to fake it if you're working from home and claiming to have 'PC issues'. (We suggest blaming your Internet router instead(
If you're keen to try the app out, just download the app for free from the App Store.
