Androidify is a great just-for-fun app that will probably appeal to lots of tablet users.
The whole app is essentially a digital android doll that you can dress up to look like whatever. You choose it's skin color, hair styles, clothing, accessories, the whole shebang. You can even alter the height and width of the arms, legs, torso, and head separately to mimic specific body types. The options are vast, and you can probably recreate anyone so that they're at least recognizable.
Once you're done, you can upload and share the androidified person to any multitude of networks. This is a silly app that will likely not hold people's attention for very long, but it can serve as a nice diversion when needed.
Start androidifying your family now with Androidify on your Android tablet.
