Digital Odometer App: Track Distance, Speed, and Routes with SpeedX

Why You Need a Digital Odometer

Whether you're a cyclist logging weekly mileage, a runner tracking training volume, or a road-tripper curious about journey stats, a digital odometer turns raw movement into actionable data. SpeedX combines GPS positioning with sophisticated distance algorithms to give you professional-grade odometer readings — right from your phone.

How SpeedX's Odometer Works

SpeedX samples your GPS position at regular intervals and calculates the cumulative distance traveled using the Haversine formula. This approach accounts for Earth's curvature, providing accurate measurements even over long distances.

Key capabilities:

• Real-time distance tracking — Watch your distance accumulate as you move, with live updates every second
• Multiple units — Switch between meters, kilometers, feet, miles, and nautical miles with a single tap
• Trip recording — Save complete journeys with distance, speed profile, altitude changes, and route maps
• Background operation — SpeedX continues tracking even when your phone is locked, perfect for long rides

Beyond Basic Distance

SpeedX doesn't just count kilometers. During a recorded trip, you get:

• Per-point speed data — See exactly how fast you were moving at each segment
• Altitude profile — Understand elevation gain and loss alongside your distance
• Shareable trip cards — Generate beautiful summary cards to share your achievements
