I've used both clothed and unclothed pix of my gf, and tbh lingerie type pix ultimately f(x) the best. Anyways, afiak the altered pix can only be saved and viewed within the wobble app, which is pretty lame imho. If someone can prove me wrong I'll post some PG13 examples.
This app is sick!! I bought it, then went on google images and got some booty and binki pictures, added the little "targets" and I have to tell you... I'm impressed. This is definitely something I'll be showing my friends later on in the day. Works great for butts as well as boobs. Actually I prefer the ass shake! Try getting a picture with multiple women in it... nice...
