UDB (User Dictionary Backup) allows you to Backup and Restore words you stored manually in the Dictionary. It also allows you to import words from a .txt list of words (each in a new line, placed in the "UserDictionaries" Folder.)
**This App might not work on Phones which provide their built-in Backup/Restore options for the User Dictionary.
