Very poor.
The app opens with a nice wood background, after that it requires a picture. But not without showing some ads first. After it fetches your pic, it will ask you to manually place the mask on top of the face. That’s already messed... there should be something to auto detect the face and its boundaries. This step completely neglects the face size and distance between eyes or eyes to mouth. After you are “all set” it takes a long time to render the final pic... about 20-30 seconds. Well come on- we could do better with emojis in half the time... But after the long waiting the app displays a dialog box, saying that you should buy the premium version and immediately opens the pay dialog. After you dodge that (and if you are not paying attention it will strike your wallet faster than it attempts to do its job!) it will display another round of advertisements before displaying the final result: first attempt I got a too big beard for the face. Understanding that, I attempted a second time- too small. It is very disturbing to use a software that works so poorly. So I decided to give up and try to prevent you guys from wasting your time, and perhaps even your money on such a crude and poorly performed application. I’ll wait for the developers commentary, but given the poor craftsmanship of this app, I sincerely doubt they will reply to this review. And if they tell me sometime that they reinvented the app completely, maybe I can give it another try, and perhaps rewrite this review. Until there I give it 1 star because 0 is not possible.
