FAST Speed Test App Reviews

Straight to the point. Light weight, no annoying ads. Does exactly what it claims. The only speed test app worth using.

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

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!

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

Throttle detector. Great app to see if your cell carrier is throttling your video streaming

Fails to run when using VPN. App works well until employing a VPN, sad

Helps me a lot!. It is the best working app

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.

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.

Bad Application””Browser””.. It feels like you are opening a browser not an app , this app should have a lot of features because it’s an APP Not a Browser , any ways it’s work fine and the speed tests are 80% Accurate .

dumb interface. if im having internet issues i want it to be expressed a bit more explicitly than staring blankly at the screen waiting for it to start.

Crash!. This app is no longer viable! Crashes more than it tests! Don’t waste your time!

No longer accurate. Download speeds are no longer accurate, which is odd considering the web version works fine.

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.

New version crashes frequently on iPad mini 5. At least it’s finally able to take up the full vertical space on iPhones with notch

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

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.

Close but not cigar. This app never gives an accurate account of my devices actual internet speed most of the time its close but not cigar.

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.

Accurate. Super quick and accurate, with no annoying ads. What more could you want?

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…

Sans Netflix.... Shall never support exploiters of children.

Close. This is the only application that comes very close to my actual Wi-Fi speed

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.

iOS Crash. It crashes on iOS. Gets up to 80mbps each time then force shuts

No dark theme?! 🤬. Doesn’t have nighttime mode 🤬

Bad have to open it 7 to 10 times to get it to get past the loading screen. Extremely unreliable and buggy wont load 80% of the time I open it crashes whenever it feels like it but ig it does well on letting me know what speeds Im at but whats the point if it only tells me 20% of the time i open the damned app

iPhone 7. Does not work on WiFi

Works on iPad, problems with iPhone. It displays accurate data on the iPad app, but on my iPhone it shows 4MB on an 80MB connection.

THIS APP ONLY MEASURES THE SPEED FROM NETFLIX.. This is not a general speed test. It only measures the speed from Netflix.

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.

Not accurate. Testing among other speed test apps this is not even close to the other speeds I get. Don’t get this.

Fast simple speed test!. Very user friendly and a very intuitive app. I totally recommend this to anyone looking for a connection speed tester with no gimmicks just numbers.

Unresponsive. App wasn’t really when I did it got really Annoying

Good but.... Good but needs updating, it closes itself.

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.

No. Tests are fully inaccurate.

Help. Force Closes

History Test Logs. Hello, Please add new features history for test logs. Fast is cool and pretty fast application. Please add few features that might use later on like the history logs. Thank you!

KEEPS CRASHING!!. Hello every time I try to be in the app for more than five seconds it crashes please fix

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.

DARK MODE. 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”

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.

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?

App Keeps Crashing. iOS 15.5 iPhone 12 Pro app keeps crashing after running the download test. The upload test starts and then the app crashes time after time.

Needs optimizing. It's pretty fast and that's great, but it's always around 0.5 Mbps less than Ookla's Speedtest (which is highly accurate). That may not sound like much when testing a 20+ Mbps connection, but it counts for those who have a slower connection.

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.

Awesome fast app. Would be perfect app if it had a packet loss tester hint hint 😋🤓

Crashes on iPhone 4. app crashes when i download on iphone 4 with ios 7.1.2 'twas the only speedtest app compatible with it in 2020.

Perfect. 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.

Misleading. On home wifi (NBN FTTH) FAST gave 9.9Mbps download . Tapped the “compare on speedtest.net” button that appeared with the result. Speedtest.net gave 31.14Mbps download. Dozens of tries all with the same difference. I wonder if Fast uses Netflix own servers for its tests.

Amazing. This app does exactly what I wanted it do to, amazing!

Hopelessly inaccurate. I’m in Australia and have a (nominally) 100Mbit link. Being Australia that means that, occasionally, I get up to 70Mbits. This app shows that I’m getting 130Mbits/sec. Seriously, Netflix, either fix this or remove it. It’s worse than useless.

Minimal. Fast and beautiful. Great for a quick speed test.

misleading. great app

Clean and simple. Nice, clean and simple, only shows download speed, but it’s enough for most users

Doesn’t work. This was advertised by Apple but doesn’t work on iOS 12. Looks like Apple just randomly pick apps.

Simple and Light. It’s great that this app doesn’t have ads, it can do the job fast, when you need to. Since it’s so simple, there isn’t much I can say except how it does it’s job faster than most speed test providers. A Dark/AMOLED mode would be nice and a setting to put the upload speed measuring automatically on the front screen instead of having to press more info. But either way, I use this app as my preferred speed test provider, and it’s almost perfect!

Gives wrong speed. read the title

Great, but needs a dark mode. Can only give 3 starts due to park of dark mode

Fast?. First test 29mb/s. 2nd test 3mb/s within 30seconds of each other. Awesome lol

Lacking. Doesn’t show anything but download speed, let alone have the option for anything else, and it can’t even get the download speed accurate. Disappointing and not worth your time.

Fast, minimal...and wrong. I’m on a 25Mb NBN plan. So why is this app telling me my speed is around 34Mb? I mean it would be great if it was...but it ain’t, and Speedtest by OOkla gives me the correct speed every time

Crashes. I have a 1 gbps Fibre connection through Telus. Every time I try Speedtest on wifi with speeds around 190-500 mbps (that’s all i get on wifi), the app crashes after few seconds. Speedtest.net test works great. Please fix.

Very good. One of the few speed test apps that measure Upload Latency with a load on it. Very reliable Makes me wonder.

Meh... Fast but not accurate. Up to 20% difference compared to other similar softwares.

Great!. Small (~1MB download) and efficient app. Nice way to quickly check download speeds. Needed to keep ISPs honest.

A great app. It’s a great app Not much storage Fast and ad free I highly recommend you buy ut

Doesn’t work. It seems like this app is given up on. No updates for two years. When app is opened, you get stuck on the loading g screen and nothing happens. 💩

keeps it simple, (the sophistication is hidden). Netflix vouches for it…all I need to know.

This sucks. This sucks

Not a native app. This is effectively a browser that displays the same web page as the one found on the website. I hate this kind of lazy work. Make a native app that, at the very least, keeps track of the tests.

Parfait 👌🏻. Super précis et j’ai configuré le test pour 4 sec,et sa prends pas bcp de données(30-40mb). Ma vitesse est là même que le site speedtest: 67down/11up 🙂

Works much better for me than other free services. My internet peaks around 2.1gbps down, 980mbps up. The Netflix fast.com app is able to reliably max out the bandwidth on my desktop’s wired connection (with 10gbe networking) whereas numerous other services such as Oomla’s speedtest.net often use no more than 1/4 the available bandwidth, leading to wildly inaccurate results. Also.. Netflix has no ads.

App crashes. The FAST app needs to be updated to make sure it doesn’t crash this always happens when leaving the app opened while the speed is being measured and we’re not using it always crashes

It works but needs update!. Please update to support iPhone X/XS Max screen resolution.

Quick and easy. This app is great if you want to be able to quickly and easily know your internet download speed.

Extremely helpful. Extremely helpful

Thumbs down. Does what it's suppose to but why is there a need for it? It's pretty dumb.

Easy but don’t trust accuracy. The results are a little wonky—not just too low sometimes, but also too high (more than my connection is capable of delivering). Stick with Ookla instead.

Great. Can not be easier to know your internet speed

Need more feedback. Work good, only need some type of progress indicator

Nice App. Like it to keep ISP on their toes. Please update for higher services. I’m suppose to have 300 down 25 up. The app never shows above 150-170 if i’m luck. Other apps show the correct speed.

Doesn't work. Can't get to server via cell data or wifi.

Really good but.... This is a great app, however I don’t really see myself using it that often

Affichage sur iPhone X. Pourriez-vous adapté l’affichage à l’iPhone X S.V.P? Merci et Bonne journée! :)

Errors a plenty. Keep getting an error that states "cannot reach our servers..."

Adsterra is the most preferred ad network for those looking for an alternative to AdSense. Adsterra is the ideal choice for new sites with low daily traffic. In order to advertise on the site in Adsterra, like other ad networks, a certain traffic limit, domain age, etc. is required. There are no strict rules. Sign up!

Why doesn’t this app EVER save settings???. Why is the option present to “Always show all metrics” if the app will never “Always show all metrics”? Fix the app or get rid of the option please.

Not worth the effort. Used app to test my internet a half a dozen times. Very inaccurate. You would be far better with Ookla Speedtest. Very accurate and more features to view how your internet works. It keeps a floating record of previous test. I found this helpful when having service calls.

Not accurate (for me) (have giga power). Ran multiple tests. Multiple devices. I got wifi AC on multiple devices. Speed test and bing get me 200-300 mpbs consistently on wifi AC And Fast is shaping 70-90mpbs. Yeah. I know. First world problems. But it's just not accurate. Maybe if you had less than a 100mpbs internet. Than fast may be accurate. But for those with 1gbps service. This isn't accurate.

App shows wrong speeds.. Tried speedtest.net which gives 30Mbps but this app shows 1.5Mbps.

UPDATE. Lazy devs

Super fast and simple. Great stuff coming out of Netflix Tech. Tech blog is an awesome read.

Defaults work ok, but tweaks confuse it. I set it to 32 minimum connections and 32 max. It then showed a 2.1gigabit connection and crashed. I'm paying for gigabit, doubt I'd get 2.1...

Comparable to actual internet speed plan. I ran the test 4 times in about 2 minutes time. The results: 1. 13 Mbps 2. 15 Mbps 3. 12 Mbps 4. 13 Mbps So, the results were not too far off, and I'm therefore averaging about 13.5 Mbps. Seems accurate as I have a 15 Mbps internet plan.

Liberty. Liberty esta usando esta aplicación como que es la mejor pero aunque no tengas el servicio trabajando eficientemente siempre te dice que tienes lo que ellos dicen. Speedtest si dice la verdadera deńal del wifi

Add iPhone X Suppprt. Great app, but I would like to see iPhone X support. I also noticed the webpage page has more details. Make the app as good or better than the webpage; otherwise, it isn’t worth downloading.

This app is really bad. It doesn't work which is not unusual but I hate when apps say they serve a purpose when really it's just a blank screen which doesn't do anything at all. This is becoming the norm these days and it's a problem.

ممتاز. أفضل تطبيق لقياس سرعة الانترنيت الحقيقية

Gets the Job Done. So few features that the second screen shot is the app literally rotated. 👌🏼

Screen resolution update. Plz bring update for iPhone xr amd xs max for full screen notch updated.

Like the idea, but doesn't actually work right. I wanted to see how fast my connection was and it told me I had 80mbps which I thought was amazing because my internet is usually crap. But then I remembered our plan is 50mbps max.

One time use only. Ok so it works that’s already 3 stars but only for one time my first one was 100 (wow spectrum was not kidding) but then it went to 80 then 76 so I don’t know what happened but it was saying my internet was slowing down simply so it works sorta

Needs iPhone X Update. Currently does not display properly on iPhone X and needs an update

Only Accurate on WiFi. Because of cellular providers being able to throttle video speeds, this app only gives realistic results on WiFi because it uses Netflix servers.

Does not work!. I used to use this app when it first came out and it was really good and fairly accurate! I guess those days are gone on Cellular I get a test of 1.4 mb I have 5G not anywhere close to accurate. Sorry but at this time I will have to pursue a new speed test. Maybe some day when this bug is fixed I’ll give it a go again but till then peace out!

Shows incorrect speed info. I wasted money on a new cable modem thinking that my internet speed was slow. It turns out that fast.com doesn’t show the correct numbers. My speed was much higher when I checked with other speed test websites

Works as described. Simple and quick.

Dini. Been waiting for this to be released. Loved the browser version, and this just brought that to mobile devices. Thanks Netflix!

Ping plz. Add ping for 5 stars. 1L

Its fantastic. This is a cool app it let know my internet speed better than ever thanks netflix and ihope you give a one month free trail for your website thanks

What a waste. Speedtest.net is 10/10 if this is 4/5. Never able to connect to server except occasionally.

Simply tells you download speed!. Simply download speed test with no ads or weird permissions. Thanks Netflix from a longtime subscriber.

Downloaded on its own?. Never downloaded this and then it appears on my phone?

Does not work. I think Netflix needs to keep to their primary role of providing movies to the public and not making applications that don't work.

Abandoned by publisher ( Netflix ). The app has not been updated in more than 2 years. The app doesn’t tell you much, not adapted for the iPhone X, iPhones Xs, iPhone Xs Max screens but it works on those.

First one to down load the app!. 😀

Simple is good. Less is more here, this is a great example of a good app.

Fantastic app but please update for iPhone X display. Love the app and it works as it should. I know this isn’t a priority but would love to see the app updated to support the iPhone X display.

Cordova app. This is just a Cordova app wrapping the website. They didn’t even bother changing the app switcher App icon from Cordova’s default robot icon.

It's a good app. But I wish to add the dark mode. It's a good app. But I wish to add the dark mode

Not optimized for iPhone X & XS. 8/30/19: This app functions, but the blank, black spaces at the top and bottom make the app unsightly. The iPhone X has been available for over a year; it’s about time Netflix updates the UI of this app.

Highly Inaccurate - Mainly from India. Compared the speedtest with other testing services and this app reports a slower down speed all the time. Mostly because they don't have globally distributed servers, would be my guess..

Not working in iphone 4. No work in iphone 4

versions. either release an apple tv version of the fast app. or build it into all versions of the netflix app

Accurate. Very accurate. The app is simple and easy to use

So fast it crashes!. Hit like 500 DL and then once it gets to near 350-400 UP the app crashes. This is on iOS 15.1. Website is great though. They should just fix the iOS app.

Awesome!. Thanks for giving us an unbiased option that shows true download speed

Simple!. Easy and FAST ☺️👍🏻

Works good. Works good. Hopefully they won't raise the price like they do to Netflix every year.

Does what it's supposed to do.. This app only tests your download speed. If you'd like something with more test results (like upload speed or ping), go with SpeedTest.

تحديث. جيد لكن يحتاج الى تحديث لدعم iPhone x

Very good. Easy to use Simple And give sufficient information

Results r inconsistent. 4 of my results gave me 4 different numbers: 80, 62, 100, 74. Way to slow than the actual speed. My device is an Ipad Pro 9.7 inch with 802.11 ac with MIMO, how is that translate to speed? Up to 867mbps of download. This is not even close

iPhone X update long overdue. I love Fast for a quick and easy check of my speed. However the display on the iPhone X is needed and long-overdue.

🤔. This shows 5mbps and speedtest shows 25mbps, which one is right?

Working well now. It connects properly now
