You don't really need a fancy app to take a selfie, just a camera pointed at your own face, but apps like Frontback make selfie taking way more fun.
It's a free download for both iPhone and Android users, and takes advantage of both your front-facing and rear-facing cameras.
The cameras capture the scene simultaneously, so you get your mug in one and what you're looking at in the other.
The photos are then displayed in a split screen, and are ready for sharing.
CamMe is an innovative free iPhone app that use gesture control to take your photos.
Raise your had to activate the camera, and then close it into a fist to start the countdown to taking a photo.
Finally, Hisy is a nifty bluetooth-enabled shutter remote that pairs with your iPhone.
You and your friends can be up to 90 feet away to activate the camera.
It costs 25 bucks, but is a great way to take a self-portrait without getting your arm in the way.
