I have no way to judge the accuracy of this internet speed testing app, but, if it is accurate, then it is a great app, because it’s fast, and it couldn’t be any simpler than it is…just click “START” and away it goes. Less than 2 minutes later you have the results….and oh, btw, my last two readings on downloading speed were 52.02 mbs and 47.07 mbs, so it does measure speeds higher than 40 mbs...
