From Daigo Wakabayashi:
NoteCube is a note taking application that has been designed to be easy and simple to use.Save text and photos that you wish to keep as notes, and view them using two display methods: the Grid view, which gives you an excellent graphical display of your list of notes, and the Timeline view, a familiar view for people who use social networking services.NoteCube is not only simple, but it is also powerful.By linking to Evernote, you can backup data on Evernote and search for images based on text detected through image character recognition.(* The image character recognition process is run by the Evernote server, so images may take some time to appear in search results.)
