The app is marvelous. Thank you! I just wish there was an app that would get rid of downloaded apps that cannot be uninstalled. dfndr does this! I was tooling around in the app and found an area that said get rid of apps you don't want. I checked it out and doggoned, this one app disappeared right before my eyes! Oh my gosh thank you thank you!

My girlfriend is the one that told me about this app. All she had was one of those free and INCREDIBLY SLOW AND CRAPPY government phones. It worked for her phone so well that I decided to use it on the last 3 phones I have had which were all name brand and somewhat fast that I actually spent money on! This app is awesome!!!
