5GMARK (3G/4G/5G speed test)

I downloaded five different speed testers to see which gave me the most functionality with a simple interface. I used all multiple times, varying the order so I could get a fairly random sample. All came back with similar results except this one which said my speed for uploading and downloading was half to a third what the others said it was with the same parameters. This app was pretty and flashy, but the results weren't presented in a clear fashion and were obviously inaccurate.

We have this on our iPhones and iPads and we've found this to be a very convenient way to quantify the wifi we have. Our internet service can be spotty so this is the best way to confirm the extent of problems we are having or by comparison, if they are getting fixed.

I love everything about this app except that I'm not getting accurate speedtest results.
