Not what you think...
This app lets you create face sketches, but it does not do a good job giving you a custom sketch based on a photograph or selfie. Most of the faces are based on predefined templates and do not look very realistic... they look more like caricatures. It might be fun for kids but do not get this if youre trying to create a custom sketch of your own face or friends.
