This group text application was originally made for teachers to notify their assigned groups of weather delays or do not report for class due to hazardous road conditions.
If you are looking for simple, this is a excellent app as it does not have a lot of extra options to confuse non-techie users.
Three buttons control the entire group text app. One to pick your desired contacts, one to remove and the other to send your text message. If you are looking for a lot of extra (unneeded) features this app may not be for you.
