The appearance of this application is very similar to social networks like Twitter or Facebook, but there are no status messages and the text is saved as a note.
The notes, at first, are private, but can be shared with others through URL, Twitter or Facebook.
The notes allow comments and even pictures can be added, which is very useful.
The notes can be classified by tags. These labels are added in the same footnote, and are identified with a pad before the start of the label as follows: # tag.
Catch.com notes includes a search engine and various methods of management for a better location of notes.
