I developed a small drawing app which allows it to share your scribbles via an account or other apps like Whatsapp or email. I started in Germany and have some users there. I want to internationalize it now and finished a good part of the English translation right now. If you are interested to test it (feedback highly appreciated), I reward your effort with a premium key.
The newest version is 1.4 which is not visible in the play store right now, but should be in an hour or so. You need at least a phone with a big screen (suggested) and Android 2.1.
