Turn your Android device into a professional Trip Computer.

Speedometer One is the most precise and feature-rich GPS Speedometer designed for your car, bike, boat, or any other vehicle. Whether you are driving on the highway, cycling through the mountains, or tracking a flight, our app delivers real-time telemetry, accurate speed tracking, and a comprehensive trip history log.

Why choose Speedometer One over other apps? We prioritize accuracy and battery efficiency. Unlike standard speed trackers, this GPS Speedometer uses advanced algorithms to correct altitude errors and filter out GPS noise, ensuring you always see the most reliable data.

✨ KEY FEATURES & BENEFITS:

🚗 Advanced GPS Speedometer
Transform your phone into a digital dashboard. Track your current speed, average speed, and maximum speed with high precision. Choose your preferred unit: mph, km/h, or knots. Our speedometer is designed to be readable at a glance, day or night.

precisely 🏔️ Real-Time Altitude Tracking (MSL)
Most apps just show raw GPS altitude, which can be off by up to 50 meters. Speedometer One is different. We have implemented an advanced Geoid Correction system to calculate the true Mean Sea Level (MSL) altitude. This makes it the perfect tool for hikers, climbers, and drivers who want exact elevation data.

📍 Comprehensive Trip Recorder
Don't just see your speed; save your entire journey. Our Trip Recorder runs in the background, logging every mile of your route. Pause, resume, and save your trips automatically. Perfect for logging business miles, road trips, or cycling workouts.

📅 Detailed Trip History & Calendar
Access all your past activities in an organized calendar view. Review your trip statistics, including total distance, duration, and average speed. Keep a digital logbook of every place you have been.

📱 Multitasking with Picture-in-Picture (PiP)
Keep an eye on your speed while using other apps. With our PiP mode, you can minimize Speedometer One into a small floating window. This allows you to use Google Maps or other navigation apps simultaneously while still monitoring your real-time speed and altitude.

HEAD Professional HUD Mode
Drive safer at night with our Head-Up Display (HUD) mode. This feature mirrors your speedometer onto your windshield, allowing you to keep your eyes on the road while monitoring your speed and limits.

📊 Interactive Charts & Analytics
Visualize your performance. PRO users can access detailed altitude and speed graphs. Analyze your elevation gain, identify where you hit your max speed, and understand your driving patterns better than ever before.

⚠️ Speed Limit Alerts
Avoid speeding tickets and drive safely. Set custom speed limits, and the app will alert you visually and audibly when you exceed them. A strictly necessary feature for city driving.

🔋 Background Tracking & Battery Saver
We optimized our GPS engine to be light on your battery. The app continues to track your trip statistics and location even when the screen is off or when you are using other apps.
