Full Screen Speedometer — Big Digital Speed Display
A giant, easy-to-read digital speedometer that fills your whole screen. Ideal for the dashboard, bike mount or night driving with HUD mode.
How to use the full screen speedometer
- Tap START and allow location access.
- Tap the ⛶ Go Full Screen button below the speedometer — the display fills your entire screen.
- For night driving, use HUD Mode instead: mirrored digits reflect in your windshield.
- The screen stays awake automatically while measuring.
Why a full screen speedometer?
Big digits are readable at a glance — essential when the phone is mounted on a bike handlebar, sitting in a car dock, or across the room. This page defaults to the digital display with numbers that scale to your screen size, and one tap takes it truly full screen with no browser bars. Combined with the built-in screen wake lock, the display never sleeps mid-journey.
Best uses
- Bike handlebar mount — glanceable speed while cycling.
- Car dashboard dock — a large secondary speedometer.
- HUD night mode — phone flat on the dash, digits mirrored into the windshield.
- Motorcycle tank bag — big digits readable through the clear pocket.

Frequently Asked Questions
How do I make the speedometer full screen?
Tap the ⛶ Full Screen chip at the top. To exit, press Back or the Esc key.
Will my phone screen turn off while measuring?
No — the page requests a screen wake lock while the speedometer is running, so the display stays on.
Can I use it as a bike speedometer?
Yes — mount your phone on the handlebar, start the tool, go full screen, and read your speed at a glance.
Does full screen use more battery?
Screen-on time is the main battery cost, same as any navigation app. Lower your brightness or plug in for long rides.
