First of all, this app is very easy to use.I had tried some other photo editors too, but they were not user friendly.
It gives a lots of effects that will change your photo completely and makes it look cool.
There is both free version and paid version of it. in paid version you will get more effects and features. but I dont think you have to buy it. free version is also very good.
It will make you look fairer. There is options of brightness, contrast, curves, etc. from which you can make your photo even look more better.
Verdict- One of the best app available in android market, And yes, best for taking selfies. so if you are a selfie lover, this app is for you.
Size is not also too high.just 30 mb.
strongly recommended.
