The block text does not work. All this App does is not allow you to see the name of the contact for a period of time. However if you know the contacts number or already have a thread going you can continue to text the person. Also, if you solve a simple math equation you can turn off the text mode, and/or you can always hit the emergency contact and still text the contact. If you are using this App then there should not be any reason the person you are blocking would be an emergency contact. The App should simply block a text from going out, period.
