TapText is an app that allows you to send over 75 different prewritten text messages to up to four contacts with only a few taps of the screen. Alert 4 people at once That you are unavailable to text, or in a meeting, or driving. Useful in class, the library, in meetings, in loud clubs, or the movies, or anywhere else that it is not possible to type messages. What's more, the text messages do not cost you anything to send since they go out through your email account.
