Free Speed Checking Explained
Many speed-checking apps charge monthly fees or require accounts. Our tool is different. It runs entirely on the GPS hardware already built into your phone — hardware you have already paid for. The web page simply reads the speed value your device calculates from satellite signals. No cloud servers crunch your data, so there is no cost to pass on.
Your Phone Does the Work
Every modern smartphone contains a GPS chipset that calculates your position and velocity from satellite signals. Our page simply reads the speed value this chipset produces. All the heavy computation happens on hardware you already own.
Satellite Signals Are Free
GPS, GLONASS, Galileo, and BeiDou satellite constellations broadcast their signals for free to anyone with a receiver. There is no subscription fee to receive satellite positioning data — it is a public utility maintained by governments worldwide.
No Data, No Cost
We do not collect, store, or process your location data on any server. Since there is no data pipeline, there is no infrastructure cost to sustain. The static web page is lightweight and inexpensive to host.
No Middleman
Unlike app-store apps that pay 15–30% platform fees and need server backends, a browser-based tool goes direct to your device. No platform cut, no server costs, no reason to charge.
What You Can Check
The free speed check gives you more than just a single number. Here is everything you see when you run a speed check on your train journey.
Current Speed
Your instantaneous ground speed, updated every second. Displayed in your choice of km/h, mph, m/s, or knots. This is the same speed measurement used by professional GPS devices.
Maximum Speed
The highest speed recorded during your current session. See the peak speed your train reached on the route — useful for spotting the fastest segments between stations.
Average Speed
Your running average speed across the entire trip, including stops. Compare this to the timetable's implied average to see whether your train is running on schedule, ahead, or behind.
Trip Data
Total distance travelled and elapsed time since you started the check. Watch your trip unfold in real time — see how far you have gone and how long the journey has taken so far.
