20·20 is the easiest way to keep a multimedia notebook. It's a sketch pad, a voice recorder, a camera and a deck of slides – all in one.
The files you create with 20·20 are automatically stored online. No need to worry about syncing files between computers and phones: your online documents are instantly available within the 20·20 application, regardless of where you are. (All you need is a Google or Gmail account.)
20·20 is also available for Mac computers. Download the Mac version for free on the developer's website!
