WhatsDraw! Messenger

WhatsDraw! Messenger is a messaging app that allows you to exchange doodle messages. It uses the Internet connection to let you doodle message to your contacts, which they will receive instantly, or when they connect.

Although the person whom you want to send the message must have the application installed, this program will let you communicate with your closest friends without spending a single cent. You'll even be able to create groups and send messages to all members.

Give your thumbs a rest, trash the keyboard and express yourself!

Pricing: First 6 months are free to try.
