Big GPS Speedometer & Car HUD

Big GPS Speedometer shows how fast you're going in one huge number you can read at a glance. Open it, allow location, and go. No account, no sign-up, nothing to set up.

A simple GPS speedometer app for anything with a missing, broken or wrong speedometer:
• Golf carts, UTVs, ATVs and side-by-sides
• E-bikes, bikes, scooters and motorcycles
• Boats and kayaks
• Tractors and farm equipment
• Classic cars and RVs
• Jeeps and trucks on bigger tires: check your speedometer against GPS speed

What it does
• Big digital speedometer in mph or km/h (tap to switch)
• Max speed and average speed
• Trip meter (trip odometer): distance for this trip, reset with two taps
• Car HUD mode (heads-up display): lay your phone flat on the dashboard at night and read your speed in the windshield
• Works offline: GPS only, no cell service or mobile data needed
• Keeps the screen on while it's open
• Portrait or landscape

Check your speedometer after new tires
Bigger tires or a new gear ratio can make your dash read wrong. Hold a steady speed, compare your dash with the GPS speed, and you'll see how far off it is.

HUD tips
• Turn the brightness up and lay the phone flat, top toward the windshield.
• It works best at night; in daylight the reflection is faint.

Privacy
Your location stays on your phone. The app uses it only to work out your speed and never sends it anywhere or stores it on a server.

Free, with one small ad
Big GPS Speedometer is free and shows one small ad at the bottom of the screen. Ads are hidden in HUD mode. The ad gets your phone's IP address, which shows roughly your city.

Good to know
GPS speed can differ a little from your vehicle's speedometer and needs a clear view of the sky. Keep your eyes on the road and follow the law.
