T9 is a predictive text technology for mobile phones (specifically those that contain a 3×4 numeric keypad). T9 stands for Text on 9 keys.

T9 combines the groups of letters on each phone key with a fast-access dictionary of words. It will then look up in the dictionary all words corresponding to the sequence of keypresses and order them by frequency of use. As T9 "gains familiarity" with the words and phrases the user commonly uses, it speeds up the process by offering the most frequently used words first and then letting the user access other choices with one or more presses of a predefined "Next" key.

The dictionary is expandable. After introducing a new word, the next time the user tries to produce that word, T9 adds it to the predictive dictionary. The user database (UDB) can be expanded via multi-tap. The implementation of the user database is dependent on the version of T9 and how T9 is actually integrated into the device. Some phone manufacturers supply a permanent user database, while others do so for the duration of the session.

Updates to the app shall be provided for any bugs and fixes.
