Tired of entering the same text or tweet over and over again? Use the Canned Response Keyboard to enter once, use everywhere.
Use the app to enter your most common texts, tweets, hashtags, messages, emails, responses, whatever and it will be readily available via the Canned Keyboard to use with one tap.
Use iCloud to sync the same keyboard across all of your iOS devices.
Note: please do not save sensitive information like passwords or addresses in the keyboard, that's what password managers are for.
