SmileOnMyMac, has updated their popular iPhone and iPad app, TextExpander, with Dropbox support. TextExpander allows you to create abbreviations for frequently used chunks of text. Many other apps, such as Twitter apps and notes and to-do apps, support TextExpander so that it’s able to be used natively in those apps.

With TextExpander touch, you create a library of abbreviation shortcuts for snippets of text that you use frequently, such as addresses, URLs, and standard replies. Tap that abbreviation, and it automatically expands to the full snippet. (You can even insert today’s date automatically with the default abbreviation “ddate”!)

You can use your TextExpander touch snippets directly in over 100 apps that support it, including Twittelator, TwitBird Pro, Elements, Simplenote, WriteRoom, Circus Ponies NoteBook, DEVONthink To Go, BusyToDo, Things, and Zendesk. See www.smilesoftware.com/applist for a complete list.

TextExpander touch [$1.99 on sale, $4.99 after Sept. 9 - iTunes link], is the iPhone (and iPod touch) version of Mac favorite TextExpander, an app that takes short bursts of text and expands them (get the name?) into longer passages.

TUAW has the details, especially on how the lack of background multitasking for 3rd party apps means the iPhone versions works (and works around) a limitation it doesn’t face on the desktop.

Check it out and let us know what you think. Or let TextExpander embiggen your thoughts. What’evs.
