Feeling a little tense, and wishing you had a notepad nearby to doodle out your stress? Perhaps you have a short note you want to pass along to a friend, or need to share information too personal for trusting to encryption. Draw whatever you like, send it, and receive and read doodles from others. A clever way to pass along a PIN number, since it doesn’t transfer as translatable text, at heart it’s just a simple, handy doodling app.
