About A-Speed
A-Speed is a GPS-powered driving companion designed for antique and vintage automobile enthusiasts. Whether you’re enjoying a weekend tour, a club event, or a scenic backroad drive, A-Speed provides modern driving information while preserving the experience of driving a classic vehicle.
Using your phone’s GPS, A-Speed calculates accurate road speed and estimates engine RPM based on your vehicle’s tire size, rear axle ratio, and overdrive settings. No additional hardware is required.
Features
• GPS Speedometer with large, easy-to-read vintage styling
• Real-time RPM calculator based on your vehicle’s configuration
• Trip odometer with automatic recovery after brief interruptions
• Driving statistics including lifetime miles, driving time, highest speed, and acceleration records
• Fuel mileage tracking with history
• Gas station locator when it’s time to refuel
• Support for multiple vehicle profiles
• Customizable dashboard color themes
• Portrait and landscape dashboard layouts
• Optional overdrive support with configurable ratios
• Achievement system to celebrate your adventures
• Automatic backup and restoration using your device’s native backup system
A-Speed is designed specifically for vintage automobiles that lack modern instrumentation. The interface is intentionally simple, readable, and easy to use while driving.
Unlike many generic GPS speedometer apps, A-Speed understands classic vehicle gearing and tire sizes, allowing it to provide realistic engine RPM estimates and driving statistics tailored to older vehicles.
Privacy First
A-Speed does not require an account.
Your vehicle information, driving history, fuel records, and settings remain on your device and participate in your phone’s built-in backup and device migration features. No cloud account is required.
Location is used only while the app is in use to provide speed, distance, and navigation-related features.

A-Speed was created by a lifelong antique automobile enthusiast who wanted a better driving companion for touring in vintage vehicles. Every feature was inspired by real-world driving experiences and feedback from fellow enthusiasts.
Whether you’re exploring country roads, participating in organized tours, or simply enjoying an afternoon drive, A-Speed provides modern driving information while respecting the character of classic automobiles.
