Hear Your Speed
A free speedometer for your phone's browser. It shows your speed in huge numbers for a handlebar or dash mount — or speaks it aloud, so your phone can stay in your pocket.
Before you start — location access
When you tap Start, your browser will ask permission to use your location. This page uses your phone's GPS to measure how fast you're moving. That's the only thing it does with your location.
- Your speed is calculated on this phone only.
- Start also asks for motion access (on iPhone a second prompt follows the location one). The accelerometer is used only to make the speed reading react faster to speed changes — GPS still anchors it, and the motion data never leaves the phone either. On current iOS there is no Settings switch for motion — permission comes only from that in-page prompt. If no prompt ever appears, the running screen's Enable motion button asks on its own and explains what to do next.
- These browser prompts are the standard way websites ask for location and motion. Websites don't get the app-style system permissions — there is no “Motion & Fitness” or Location Services screen a website can call up; the browser's own Allow prompt, triggered by the tap, is all there is. Those prompts can only appear when the page is open on its own in Safari or Chrome — a view embedded inside another app can't present them.
- Nothing is sent to a server. There is no account, no sign-up, and no cost.
- Nothing about your trip is stored — close the page and it's gone.
- No analytics, no advertising, no tracking cookies.
Stay safe
- This is not a substitute for a vehicle's speedometer or posted speed limits. GPS speed can lag or drift, especially under trees, tunnels, and tall buildings.
- Set it up before you move. Never tap the phone while driving or riding.
- On shared trails and roads, keep one ear open — use one earbud or a low volume so you can hear traffic and other riders.
Keep the screen open
While running, this page asks your browser to keep the screen awake. A website can't guarantee that GPS or audio keeps running once a phone is locked — on iPhone especially, Safari may pause them. Keep this page on screen while you ride or drive.
Tapping Start opens your browser's location permission prompt — choose Allow when it appears. You'll hear a short chime and a spoken confirmation as soon as it starts, so you know sound is working before you set off. You can stop anytime with the Stop button, and revoking location permission in your browser settings stops it completely.
