BestMe Selfie Camera is an app by Riley Cillian, developer of multiple other photography apps. As you'd expect, it provides filters, stickers and all kinds of eye candy to add to the selfies you take with it, and it plays nice with popular photo service Instagram, too.
A camera with many lens
The camera functionality of BestMe Selfie Camera isn't much better than the default camera app on your phone, sadly. A few users even report problems with it, such as having to flip their images vertically because the camera is flipped by default (but we were unable to reproduce this in our testing!). Where it really shines is the 125 real-time filters it lets you apply to your selfie, before or after it's taken. When you're done, you can add stickers too, and upload (sans cropping!) to Instagram without any issues. It's workable with Facebook, too.
Basically, BestMe Selfie Camera is even better as a selfie improving app than as a camera. Though it lacks some functions that could make life a bit easier, those aren't really necessary when you're in the thick of things, getting the best possible look for you out of the camera, onto your phone, and made even more perfect. So basically, definitely try BestMe Selfie Camera if you're into that.
