IOS15.3 issue

I have been using this app for quite a while. It is the closest to real world that I have found in any Speed test app. I really like that I can run longer tests if necessary and I can change settings as needed.
Since the 15.3 iOS update the app crashes when the upload test is completing. I can watch the readout and get the info I need but it would be nine if it would stop crashing.
Otherwise it’s great.

Measures Net neutrally throttling?

The difference between the speed figures between this and other apps isn’t a flaw, it’s a feature. It can’t be coincidence this app premiered just as FCC relaxed net neutrality. This is a clever way to measure the degree which your ISP throttles the Netflix streaming service. Test your cellular data provider or public WiFi with this app and then with this app and then with another, see how much slower the figure Fast app shows? That’s how some much ISPs are discriminating from one service to another. Giving benefit of the doubt, much of the throttling may just be a way of preventing one user from bogarting the bandwidth on a public WiFi system.

Recommended by my company I.T. Tech

Before my company's in-house IT Technician told me about fast[dot]com, I didn't know it was possible to check your own internet "speed(s)" (upload rate/download rate.)

I use their website to check my computers' internet speed at work & home and now, I use the iPhone app, which allows me to see my cellular data speed, as well as my WiFi speed; independently from one-another.

It's great for confirming public WiFi hotspot speeds, too.

The FAST App is somewhat more convenient than opening a browser on my iPhone & going to their website (which does the exact same thing as the app.)

A Tech-Support Agent with my cellular provider also recommended using this app.
