GPS Speedometer: Odometer HUD

GPS Speedometer is an accurate speed tracker, digital odometer and HUD speedometer — speed, trips and history work offline, with no account.

Whether you drive a car, ride a motorbike, cycle or sail, this GPS speed tracker shows your real speed measured by satellites, independent of your vehicle's dashboard.

MAIN FEATURES

• Analog + digital speedometer — a smooth needle and a large digital read-out
• km/h, mph and knots — one tap switches units
• HUD mode (head-up display) — mirrors the screen so you can place the phone under the windshield and see your speed reflected on the glass at night
• Speed limit alert — set your own limit; the screen flashes red and the phone beeps the moment you exceed it
• Trip meter & odometer — distance, maximum speed, average speed and moving time for the current trip
• Trip history — every trip is saved on your device; review, or delete trips at any time
• Battery use per hour, measured on this phone, a hot-phone warning and Eco GPS
• Voice alerts over the limit that only lower your music, plus one-tap limit presets
• Elevation chart with total climb for every trip
• Live Update speed chip on Android 16
• Fuel trip: live fuel and cost for a drive, a fuel trip log, L/100 km ↔ mpg converter, service reminders to your calendar (.ics)

FREE OR PRO

No ads while driving, pay once. The free banner hides as soon as you move and never shows in HUD or Drive mode. Pro removes ads and unlocks 6 extra gauge themes, a resizable floating window, GPX/CSV export and unlimited trip history — monthly, yearly, or a one-time Lifetime purchase.
• Runs on Android 7.0+; everything except the map works with no connection

WHY THIS NUMBER — A SCREEN NO OTHER SPEEDOMETER HAS

None of the others tells you whether the signal is good right now. Tap the accuracy figure:
• The plain verdict — good signal, weak signal, or "the number you see is the last fix received, not your speed now"
• The measurements behind it: accuracy radius, age of the last fix, the update rate your phone actually delivers, satellites used out of visible, and whether speed comes from the GPS chip or from distance ÷ time
• Why your dashboard reads higher, why the number trails the car, why it drifts while parked

0–100 KM/H TIMER THAT ADMITS ITS OWN MARGIN

• Stop, tap Ready, drive — timing starts by itself, stops at 100 km/h (or 0–60 mph)
• Start and finish are interpolated between fixes, so two runs are comparable
• Every result carries a ± figure, because a fix once or twice a second cannot pin the exact instant of crossing
• If the signal drops mid-run, the run is voided and you are told why
• For closed courses only, never on a public road

PRIVACY FIRST

Your location is used only on this device to compute your speed. Your position, your trips and your track are never uploaded, shared or sold: they stay in the app's local database and you can delete them at any time. The Map tab downloads map tiles from OpenStreetMap when you look at an area for the first time — that request carries the map square, not your identity. Anonymous usage counts and crash reports (Firebase) contain no location. The free version shows Google AdMob ads, which may use your advertising ID; Pro has no ads.

WHO IS IT FOR?

• Drivers who want to verify their car speedometer (dashboards often over-read by 5–10%)
• Motorbike and scooter riders with a broken or inaccurate speed gauge
• Delivery and ride-hailing drivers who need a trip odometer and distance log
• Cyclists, runners, boaters

TIPS FOR BEST ACCURACY

• Use outdoors with a clear view of the sky; GPS speed is typically accurate within 2–5 km/h

SAFETY DISCLAIMER

Do not operate or interact with this app while driving. Set your units and speed limit before you start moving, mount the device securely, and always obey local traffic laws and posted speed limits. GPS speed is informational and can differ from your true speed; it is not a legal defence against speeding tickets.
