GPS Speedometer Online FAQ

Is the information provided by the online GPS speedometer accurate?

The values of speed and time are more of a reference. It's better to be guided by the numbers displayed in a physical speedometer installed in the vehicle. At least, this option is recommended by Google Maps developers when you check your speed.

Are there separate apps for determining speed? I want to know how fast I'm going and if the speedometer in my car is working correctly.

You can do this by installing a free online speedometer app by downloading it from the Google Play Store.

The best GPS speed test apps are collected in our review: Speedometers for Android on MyGPSTools.

Can I trust my phone's GPS speedometer? How accurate is the speed checking?

Figures that software speedometers provide can be trusted only in part, as they still have an error margin and are quite slow to respond to speed changes.

It is always advisable to use an ordinary car speedometer or onboard PC in addition to an online speed test tool.

You mentioned Android applications. How do I check my current speed using my iPhone?

Here is the iOS app Speedometer - How Fast Am I? by Marcel Kraus.

It's completely free and has no ads. The speedometer reviews are positive - written by motorists and even golfers who use carts. The app makes it very convenient to switch between meters, MPH and KPH. There is a dark mode, which turns on automatically if you have the appropriate mode on your iPad or iPhone.

Is it possible to know my current speed without a speedometer?

Yes! The standard distance between 10 poles is about 1/4 mile. Multiply the number of seconds by four, then divide by 60 and multiply by 60. This will be equal to your speed in miles per hour (MPH).

How does GPS calculate the speed of a vehicle?

GPS receivers, for the most part, calculate speed through Kalman filter algorithms. This is a combination of measuring movement per unit time and calculating the Doppler shift in the signals. The speed is not displayed as a numerical value in real time but processed to show you an accurate result when you check your speed online.
