### 2/5 — Doesn’t work.

*2025-08-28, version 12.2*

Difficult to use, doesn’t work on iPhone. Waste of money.

### 2/5 — Does not work with iPhone 11 iOS 16

*2022-11-13, version 12.2*

Have tried every possible setting, camera angle, tripod, … but app consistently reports vehicles going 4 to 6 miles per hour.

### 2/5 — Hit and miss

*2022-08-08*

I’ve been using the app now for about two weeks. I have noticed if I am in a shadow and the subject areas and light it does not work well I’m not I’m also having issues on Cloutier days is not working this morning and it works great afternoon zero very disappointing.

### 1/5 — Rubbish

*2021-11-25*

Poorly explained App making very hard for the application intended like speed checking vehicles 
Want my cash back

### 2/5 — Neighbors

*2021-11-05, version 12.2*

I purchased this yesterday and it seemed that it was going to be easy to use but I am not picking up any speed from any of the cars. What’s the deal?

### 1/5 — Completely unreliable

*2021-10-08*

I had high hopes but this app gives consistently incorrect data. I even mounted my phone to a tripod and used a tape measure to calibrate the distance to subject (roadway). After trying many different settings I gave up. We have many speeders in my neighborhood and I wanted to record vehicle speeds. I would say 50% of all data was incorrect and no way I could possibly use it reliably.

### 2/5 — Gear idea, completely unreliable.

*2021-06-28*

Constant freezing and data point error pop ups. No graceful reset/restart if an error. Speeds tragically inaccurate. Also appears to be abandon ware sense the support site doesn’t actually exist.

### 1/5 — Doesn’t Work

*2021-05-29*

Should have trusted previous reviewers, I couldn’t get this to work at all for simply measuring cars passing on the street. Tried all options, wasted two hours. $4.47Cdn wasted. iPhone Xs, 14.4.2.  Apple shouldn’t permit such crappy software in their AppStore.

### 2/5 — Old version was great.

*2021-05-14, version 12.1*

Update made it not work.

### 1/5 — Doesn’t work

*2021-03-11*

Brought this app, to see how fast some cars are going past my local school, during pickup time. Several cars went past & it never picked up any. Did adjust distance & still nothing.

### 1/5 — Disappointing

*2021-02-27*

My kid wanted me to get the speed of him on his bicycle. And it doesn’t appear to work at all. Save your money. When I put it on the live which it recommends using to do some thing like this. The second you press start it automatically shows you what speed Keep in mind this continues to happen even though there’s nothing moving. The second I press start it automatically shows me a time repeatedly. Very frustrating. So far I’m regretting the three dollars I spent on this

### 2/5 — Try it

*2021-01-18, version 12.0*

Not for me. Everything has to be set with no obstacles in view.

### 1/5 — Worst app I’ve ever had

*2020-12-07*

I dropped the pins in the location I needed them and saved as soon as I open the app it’s set somewhere else.  I gave it one star because I had no other option when in reality it should be one star negative. Everyone that paid for this app should get a refund.

### 4/5 — Speed Clock Review

*2020-11-10*

I am in safety on a job site and use the speed clock app daily for my job to keep speeding down on the job site! For the most part I like using it and like the features it offers. I am able to show them their speed with no contesting! I feel a five rating could be in order if it would work each time it’s hard to learn it and calibrate until u get used to it!

### 1/5 — Background motion

*2020-10-07, version 11.1*

App keeps flashing background motion and doesn’t register speed despite placing on surface.  Using iPhone 11. Don’t purchase

## Most critical reviews (10 lowest-rated)

### 1/5 — Golf swing

*2025-11-14, version 12.2*

Has trouble tracking specific objects especially if things are close by, don’t recommend for anything more than 60 mph

### 1/5 — Ging früher sehr gut.

*2025-09-13*

Seit 3 Jahren kein Upgrade mehr. Aktuell keine Möglichkeit mehr, Geschwindigkeiten zu messen.

### 1/5 — Geht nur manchmal

*2025-09-06*

Funktioniert nur in seltenen Fällen. Woran es liegt, keine Ahnung. Geld ist weg.

### 1/5 — Seems to have a Major Glitch

*2024-05-01*

I’ve been trying to use it on a narrow road with traffic coming from both directions. So two distances (say 1m and 3m) set up.  However, the speed recorded seems to be only 50% of the actual speed.  Looks like a coding issue but ruins a potentially great app.

### 1/5 — Waste of money

*2024-04-01*

Even when it did register something, and after I set car length etc. It still showed cars doing over 200km hr as doing 50 or didn’t register. Don’t bother.

### 1/5 — Doesn’t really work

*2023-08-23*

Bit annoyed - bought this to measure speed of cricket bowling ~75mph. Couldn’t handle it at all.

### 1/5 — Disappointed so far

*2023-07-13*

This app is not at all accurate, and trying to get through all the setup parameters is a pain, it gives you error messages but no way to fix them; i.e. “not enough pinned points for reference”. I had hopes I would be able to use this app to provide data to my local police regarding the speed problem on my street, but the apps data is useless.

### 1/5 — Wildly Inaccurate

*2023-02-26*

I wanted to recommend this app to people in our private neighborhood to clock traffic. After an hour of experimenting, I clocked a golf cart doing 108 miles an hour, several other slow moving cars at over 150 miles an hour. 

I moved to three different locations and each showed 20 to 30 mile an hour traffic indicating over 100 according to the app.

After watching the tutorial again and resetting the program disparate traffic were all clocked at 17.6 mph on a private street.

Unusable.

### 1/5 — Waste of time and money

*2022-10-23, version 12.2*

This app is a fantastic idea. Unfortunately it doesn’t work like it’s marketed to. Inaccurate at least half of the time and the other half a message pops up saying it can’t get a good estimate for one reason or the other. I want my money back.

### 1/5 — Doesn’t work at all. Save your money

*2022-05-03, version 12.2*

Haven’t gotten the app to recognize a single object in Live Speed, the only useful function to track and log cars speeding by my house. Save your money and don’t buy.

### 5/5 — Great

*2025-12-14*

Does what it says with a few extras like distances

### 5/5 — Фіксація предметів

*2025-09-13, version 12.2*

Дякую хороший додаток але ви могли ще додати таку функцію щоб із багатьох предметів можна було вибрати один предмет і коли він рухається він слідкував за цим предметом?

### 5/5 — Speed clock

*2024-06-27*

I’ve been using this on my iPhone on and off for a couple of years and it works without any issues. Captures speed of vehicles and captures a snapshot with a time stamp. There is a slight glitch when stopping recording and pressing the menu option as it ask for translation, however this does not stop the app from working and is very minor problem. Brilliant app.

### 5/5 — Works perfectly!

*2023-11-03*

Worked perfectly straight out of the box. Even at night, under streetlights, it records the speed of passing cars and saves the photo to your camera roll. Very impressive app. Thank you.

### 5/5 — My Application

*2021-06-14*

It is essential that the user learn the operation and limitations of the application. Once understood, Ithe user will be able to apply it to testing speeds on a roadway.  

The application did exactly what it was designed to do. 

I verified the speeds with Doppler and laser technologies and so long as my distance from the target vehicle was accurate, SpeedClock was accurate +/- .5 mph. 

Recommend it? 

Yes!    But understand the application, operations, and limitations.

### 5/5 — Super function

*2020-09-01*

Everything works as it should and easy, straightforward setup. Very happy with the app and support from Sten Kaiser. 
First class.

### 5/5 — Perfect!!!

*2020-06-20*

Using and iPhone XS, completely updated with the latest IOS. If any thinks this will work correctly in 5 minutes, you’ll be disappointed. This is not a fire and forget app. You need to measure your distance properly. Insure your field of view is clear. Pan down if there are a lot of trees in the background and it’s windy. Adjust your settings tracking sensitivity to about the mid-point (worked best for me). Also, check the zoom as your tracking. Zoomed far out, I had a lot of trouble getting a reading. However, zooming in to a tracking distance of about 25/30 feet, from start to end, and it caught the speeds nearly every time. If you press Start, and you get a tracking error (background movement, etc), just tap Stop, then Start again. This seemed to stabilize things. Try and line your tracking boxes (the Red bars on either side) up with a fixed point to insure a good track. And most importantly, hold it very very still (a tripod would be perfect). 
DONT take the overall rating as this is a bad app. Many factors come into play when using this. This is why in the beginning of my review, I said what phone I was using, and if it was up to date.
ENJOY!!!

### 5/5 — Excellent, and for the price, incredible!

*2020-06-19*

I installed the SpeedClock App on my iPhone X. I positioned the iPhone on a tripod in my driveway with a clear view of my street. I accurately measured the distance from the iPhone to the center of the street (43 feet) and input that number into the App as per the instructions. I drove down the street several times at 30 mph and found the App measured and recorded my speed accurately to within a couple of mph. I also used the option to capture the image which shows speed, date and time. I am the HOA President and I can use this App to help identify the speedsters in our neighborhood. My thanks to the developer!

### 5/5 — Super! EMPFEHLUNG

*2020-05-20*

Sehr genau, super Support. Klasse Funktionen 👍🏼
Ich hätte auch 20€ dafür bezahlt.

### 5/5 — It was worth the cost

*2019-07-14*

This item has provided hours of countless arguments debates and fun.  I really enjoyed the hours and days, so far, since we’ve had this app
Thank you
