Description

The iPhone speed radar - easy-to-use speed measurement in your pocket, anytime, anywhere! A unique, advanced app designed to easily measure the speed of cars, boats, skaters, skiers, cyclists, animals, models, footballs, tennis serves, etc. The system is based on motion detection, enabling you to track a moving object using a hand-held device alone. SpeedClock includes three separate speed measurement tools and two distance estimation tools. 

 Speed Radar 
 SpeedClock uses the camera to detect and analyze motion, and a reference distance to calculate the speed of an object. Define the distance to the object of interest, hold the iPhone still and let the object pass across the the screen. The speed is displayed automatically. SpeedClock is also able to automatically measure the speed and save an image of passing objects. The measurement can be initiated from an Apple Watch and the speed displayed on the watch face. 

High Speed Video Recording
 An additional speed tool records and processes a video, which enables SpeedClock to track small, fast object, such as flying balls, that can be difficult to catch with regular motion detection. 

It also calculates additional parameters like acceleration. Synchronized Timing Gates
 A third speed instrument uses two iPhone/iPads equipped with motion detection to start and stop the timer and measure the speed. The distance between the devices is used as reference, and the speed is calculated based on the time taken by the object to travel between the 'Start' and 'Stop' devices. The time is transmitted wirelessly over WiFi or Bluetooth. 

Distance Measurement 
The stadimeter uses the size of a known object, e.g. a car, to calculate the distance. 
The clinometer uses your own height as reference, along with the angle of the iPhone, to estimate the distance to a point on the ground. 
The distances obtained from either tool can then be used to calculate the speed.

★★★★Golf swing🇺🇸 US

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

ScuffedSdnich· 2025-11-14
★★★★★Фіксація предметів🇺🇸 US

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?

★★★★★Doesn’t work.Bugs/Errors🇺🇸 US

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

★★★★Disappointed so farContent Quality🇺🇸 US

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.

Aiko Akita· 2023-07-13
★★★★Wildly InaccurateContent Quality🇺🇸 US

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.

★★★★★Does not work with iPhone 11 iOS 16Bugs/Errors🇺🇸 US

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

Roostergx· 2022-11-13
★★★★★Hit and missBugs/Errors🇺🇸 US

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.

kevin L 623· 2022-08-08
★★★★Doesn’t work at all. Save your money🇺🇸 US

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.

Johnfayjr· 2022-05-03
★★★★★Neighbors🇺🇸 US

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?

★★★★Completely unreliable🇺🇸 US

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.
