Text Tap app allows you to send a preset text message in only two taps. Once the app is open, tap on the message and then tap "Send" to confirm. The app is ridiculously simple and easy to use for the moments when a quick reply is required, but you don't have the time to write a text message. For example, you've just started to work-out, and your friend texts you to see if you want to go to the movies. Instead of interrupting your exercise to compose a reply message.
