ColorFriends app for iPhone and iPad

Color together with the picture shared on all the shared devices.

No in app purchases or anything else, ever. Just pair over bluetooth with another device and share the coloring.

No internet connection required or any stranger danger, both users must be in the same room and with both Apple touch devices within Bluetooth range of each other. Pair the devices by pressing the button with the BlueTooth "B" logo with two people next to it.
Request on one of devices and accept on the other device.
Paint on either or both and it shows up on both devices at the same time.
