I have been using this app for more than one year in my android phone.And from my experience I should say that this application is so much user friendly.
Its basically designed clean and elagant.Any one who opens this application will not feel disturbed.
The specification provided and so much useful.The editing and color grading features are so nice.This itself could be used as a mobile photoshop if needed.it is very handy and helpful.
Photos saved by this application has only a small size, so that we could upload or share it very easily without the lose of huge data.
I always like to make my whatsapp and facebook profile pictures out of it.
