I had downloaded youcam perfect a month ago to enhance the cameras effects on my mobile and yes it is good but up to some extent the blur feature of this app is aweful and in some effects picture gets higly saturated suppoese if you took a picture on a sunny day with your face facing toward sun you will get a blemished picture even it took nice images in shadow and snow but some times the effects and filters are not good. Even normal camera of my phone took better images in certain conditions and you cant focus on an object easily. I hope they will fix it soon I will rate them good .
