GPS Speedometer & MPH Tracker

Turn your Android into a professional GPS speedometer app, mileage tracker, and head up display (HUD). Ever wondered "how fast am i going?" Speedometer One checks your real-time speed in MPH or KM/H, runs a digital odometer, tracks elevation, and logs every trip with its fuel cost — all in the background.

Need a reliable car speedometer, a simple spedometer app, or an app to tell car speed? We provide precise speedometer gps real time tracking for daily driving.

🚗 GPS Speedometer — MPH, KM/H & Knots
Our large display shows real-time, average, and top speed with GPS precision. Readable day or night. Choose miles per hour (MPH) for US driving, KM/H for international routes, or Knots on the water. Find out exactly "whats my speed mph" at any moment.

🪟 Head Up Display (HUD) Mode
Project your speed onto your windshield. The head up display mirrors your readout in reverse so it reflects perfectly off the glass — safe, eyes-on-the-road driving with no extra hardware required.

📍 Mileage & Driving Tracker
Track my speed for car driving and save the route. Every trip is automatically recorded: distance, duration, average/top speed, and elevation. The perfect mileage log for business miles, IRS mileage records, expense claims, or personal tracking.

⛽ Fuel Cost & Mileage Reimbursement
Enter your car's fuel consumption and gas price once and every trip gets its own cost. Tag a drive with who pays to see what it is worth back at your own rate per mile or km. Totals by day, week, month or year, exported to CSV, Excel or PDF. Day and week are free.

📏 Car Digital Odometer & Distance Log
Tracks cumulative trip distance exactly like a car digital odometer. Ideal for logging delivery miles or keeping a personal driving log. Works for cars, motorcycles, e-bikes, boats, and any vehicle.

🏔️ Altitude & Elevation (MSL)
Most apps show raw GPS altitude, off by 50+ meters. Our advanced Geoid Correction calculates true Mean Sea Level (MSL) elevation. Accurate altitude data for mountain roads, hiking, trail running, and aviation.

⚠️ Speed Limit App & Alerts
