Skitch's main interface lets you move comfortably between the different types of media with which you can work. Sliding from left to right, you can access photos, maps, websites, PDF documents, or even blank documents. Simply select one of them to start using your finger as a marker.
Skitch includes classic writing tools like colored markers and others to create arrows, insert text, or underline words. All the editing tools, including one for censoring, are perfectly designed to work on photos and maps.
Skitch is a very interesting tool that should prove very useful for anyone who wants to take notes from their Android. And once you finish, you can share your work with any app installed on your device.
