- Mi Face
- eMees
- PicBook

All of them are a bit different. From a graphical point of you I found MiFace to be less compelling. The designs are pretty simple and the user interface is absolutely not up to what is possible on the iPhone. Although MiFace offers the biggest selection of assets.

eMees has very nicely designed assets and the user interface is cool with a lot of functionality. And the price tag is cheaper with 99 Cents. It feels a bit sluggish sometimes but that can be solved in an updated version I guess.

PicBook is relatively new and offers rather basic functions. A couple of assets are available so that you can create a face quite quickly what remembers you at least a bit of the real person. Still some things what are not working perfect. For example you can change (and I do that unintentionally…) the color of the skin when tapping next to a face. But for 99 Cents it is quite nice.

In my opinion it depends of what you want. I looked for an app what lets you create pics that look a bit like my friends. Therefore I prefer picbook to do this. eMees faces are way cooler and it is funny to add that to a friend. MiFace was bought by me when they lowered the price once. But I really cannot see why someone likes that…
