I just downloaded this am app tonight so have not given it a test run. It is designed to help you save on your data plan each month. The data is compressed over a 3G, EDGE, and LTE networks. The only concern I have is that you have to send the data through their server. This is the same server as Facebook. The app is simple to use with a set it and forget it approach. Also works on 3G, 4G, and LTE.
