Apple has just released an update to zintin on the iPhone app store. The update contains a whole load of nice features, but the big one is scribbling. Scribble was launched as a separate app and blew up; it has been one of the top apps since shortly after it was released. The Scribble app is included entirely in the update to zintin, with a fun addition. In zintin you will be able to scribble on pictures in addition to a plain white background.
Aside from all the fun, scribbling is a great way to send short notes to other users. Until now, many users have been sending such notes by taking screenshots. We are currently working on the next update which will allow for even more interaction between users.
