A free program for Android, by QB9 Entertainment.

The QB9’s 3D Skin Editor for Minecraft is the official skin editor for the Gaturro and Messi servers. The app allows you to create customized skins based on some of the most popular footballers in the world, such as QB9 and Leo Messi. Choose the player you want to edit and make the necessary changes to improve your appearance. You can edit the skin – add textures, intensify spots or stubble, add identifying marks, and just augment the overall quality. Add other such details like wrinkles and blemishes, to make your character look more realistic. The app has many options and tools for customizing skin quality, like a regular paint tool, an eraser, a paint bucket, and a color picker.
