Just for fun !! Put any picture over faces in your photos like masks. This app detect faces and you select any photo to mask, is very cool. First you add the background photo, then add mask photo in ☺ emoji icon, To remove a mask, use X, and if you want you can post.
Warning ! when you load the background photo, wait to see a lightgreen box around the face, if you don't see, load other photo please !!
For best results of the mask, use transparent .PNG files (try download of the internet or make your transparent .PNG removing the background of the .PNG file in a graphic tool)
