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.

Realistic speed test results for streaming media
A lot of mobile carriers throttle Netflix and other streaming providers. Do you want to know how much they are throttling you? Run this and compare it to another speed test. You’ll probably find that video is being throttled to only a few megabits. Other reviews of this app that complain about in accuracy are missing the point. What good does super fast 5G do if your carrier won’t let you use it for high quality streaming?

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.

Reliable. Please offer dark mode
My go-to app any time I need to check the Wi-Fi speed. Please consider adding a dark mode with the next update!

Love how simple the app is but would like to have dark mode… Also, would love to have a way to have upload speed to run automatically from a setting within the app -instead of tapping “more info”

Checkboxes to save settings not showing
The checkboxes to save various advanced setting are not appearing. My phone uses dark mode, so perhaps the outline for those boxes is automatically switching to white, which makes them invisible against the unchanging white background of the app.

Very misleading
This app doesn’t tell you your actual download speed, especially on a cellular connection. The app needs to disclose that it’s only for testing Netflix connections and not for others. I’m very annoyed because my actual download was about 110mbps instead of the 4mbps it gave me.

Works on Wi-Fi inaccurate on mobile
Works great on Wi-Fi. Not accurate compared to other apps on mobile. It was always vastly underestimating my signal. Does that mean Verizon in really throttling Netflix? Maybe…

Shows incorrect speed on T-Mobile 5G
It shows my download speed at 2.4 when connected to T-mobile 5G-UC network. Spent hours with T-mobile support only to find the speed was 500Mbps correct shown by Speedtest. Fix the issue Netflix

Inaccurate 5G speeds shown
This app was showing 1.5 Mb/s, causing me to reset my connection thinking there was an error. After double checking on Speedtest, found my actual speeds were 150 Mb/s. Will not be using this app unless this is fixed.

Highly Inaccurate (2020)
Definitely do not use this app as your speed test provider, Netflix is a joke for even thinking this was remotely a good idea. Stick to the streaming service only.

It Works
It's a simple app. It does what it is supposed to and quickly. I still prefer SpeedTest but if I need a quick gauge I will pull this up instead. One thing to make this better is simply historical data.

Needs a little work
I hope this gets read by someone in charge. The app is good but needs work. On older iOS devices, iPad 4th gen, it seems to crash after it gets done. It makes the screen go black for several seconds. Other than that it is good. But the crash at the end of a testing is annoying. Please fix. Thank you.

Plain and simple: it works.
The app is small and not the most attractive or feature rich. That's what makes it so amazing. It's super fast at telling you just what you want to know if your a media consumer. I will say that the fact they are not measuring upload or jitter or ping time they can give a far more accurate download measurement. If your a technical person who needs upload stats or well any other information than a pure download speed measurement than I would look elsewhere.

Now what?
So I know my speed. Now what? Why, oh why would you not include in this app recommended speeds for a quality connection to Netflix? Speeds for solid 4K so I can pay you more money. Speeds for other resolutions so I can keep paying you money. Display the best resolution you can expect right next to the download speed.

Works great but...
This works better than Speedtest. On Speedtest it says I had 50Mbps download then I Used this and it said I had 200Mbps which I pay for 180Mbps.. But can you add a upload speed too

Fundamentally flawed
I am probably being harsh here, because I'm so frustrated with sub-par applications like this… There is a serious defect in this application… If you start it when the Internet is not connected, you'll get a button that says "Retry"… And even after you connect to the Internet, the button is persistent and won't go away, and you have to close the app and restart it in order to run the speed test. I have reproduced this bug several times, it's amazing to me that this escaped into the released application. Otherwise, the application does what it's supposed to, very simply and adequately. But this fundamental flaw makes me give it a very liberatingy

Someone finally made a speed test that’s not riddled with ads. It’s simple and now that it reports upload speeds and ping it’s the best option by far.
