A great timesaver, this Mac and iPhone/iPad application allows you to assign shortcuts or abbreviations for commonly used phrases, signatures, email addresses, etc. If you use more than one computer, your shortcuts or snippets can sync via Dropbox. An added plus if you also use Windows, the TextExpander snippets and settings file can be used by the Windows app Breevy, allowing you to share the same shortcuts between both computers. TextExpander offers a free trial of the Mac version. TextExpander: (Mac): $34.95 (iPhone/iPad):$4.99
