Buyers remorse can be a terrible thing as you always wonder if you'd have been better off picking the other device when stood in the aisle at Best Buy. Thankfully if you've got $7.99 lying around and kinda regret grabbing Amazon's Fire TV, then help is at hand thanks to YouMap. The app enables you to trick the hardware into thinking that it's a Chromecast, letting you mirror your Chrome browsing or push YouTube clips straight from your smartphone. The app works for both the Fire TV and the stick, and while it won't give you all the functionality of Google's video dongle, you'll at least be able to see how the other half live.
