For cyclists
Bike Speedometer — Turn Your Phone Into a Bike Computer
Turn your phone into a bike speedometer — mount it on your handlebars, tap Start, and see live speed, average, max and distance.
Framed for cyclists. Mentions phone-mount use, keep-screen-awake relevance (so you see speed without waking), and battery tip: GPS drains battery — lower screen brightness and close other apps. Works with any bike, no sensors needed.
Tap Start to measure your speed. Your browser will ask for location permission — coordinates are processed locally and never sent anywhere.

Off by default. Only active while tracking — we never keep your screen on otherwise.
Mount, don’t hold. Use a handlebar mount so you keep both hands on the bars.

Bike mount & keep-screen-awake
Toggle “Keep screen awake while tracking” so the display stays on at a glance. Remember GPS uses battery — bring a power bank for long rides.
Battery saving
Dim screen, turn off Bluetooth if not needed, and pause the tracker on long stops so elapsed time stays accurate and you save power.
Privacy-first — coordinates never leave your device
Processed locally in your browser, never stored on a server. Close the tab and it's gone. Learn how GPS speed is measured →

Will this drain my battery?
