Built for the road
Six reasons people open Zpeed.
Verify your dash.
Your phone's GPS gives a precise digital readout — useful when you want to see how closely your vehicle's display matches actual speed.
Speed without hardware.
Mount your phone on the bars and read live pace without pairing a sensor or magnet. Works as long as you have open sky above you.
Know your outdoor pace.
Track km/h or mph in real time on outdoor runs. GPS measures movement across the ground — it won't register on a treadmill.
On the water, too.
GPS signal is just as reliable over open water as on land. Cross-check your vessel's display without any extra equipment.
Your peak on that run.
Carry your phone down the slope and check your top speed after you reach the bottom. No installation or pairing required.
Train, bus, or ferry.
Sit back on any vehicle and see exactly how fast you're moving. No app needed — just a browser and a clear signal.

Good to know
Things worth knowing.
01How accurate is a GPS-based browser speedometer?⌄
In open sky, modern phones fix your position to within 10–40 metres. Speed is derived from successive readings, so at typical road or cycling speeds the result is very close to actual. Accuracy drops in tunnels, indoors, or between tall buildings.
02Does it work without an internet connection?⌄
Once loaded, yes. Zpeed is a Progressive Web App — add it to your home screen and the speedometer is cached and available offline. GPS works independently of your internet connection.
03Why does it show 0 when I'm moving?⌄
GPS needs a few seconds to acquire a signal after you grant permission. Once the status shows GPS Ready, a zero reading means you are genuinely stationary — or the signal has temporarily dropped.
04Will it work on a treadmill?⌄
No. GPS tracks physical movement across the ground. On a treadmill your position does not change, so there is nothing for the satellites to measure. Check the treadmill console instead.
05Why do I have to allow location permission?⌄
The browser's Geolocation API requires explicit consent before sharing any position data. Zpeed does not ask on page load — you trigger it by tapping Start tracking. No permission, no tracking.
06Is my location sent anywhere?⌄
No. Speed is calculated inside your browser using the device's GPS chip. Nothing is uploaded to a server. Zpeed does not require an account or store any location history.
