Urban Biker

Track your rides, runs, walks and fitness activities with precision using Urban Biker, the privacy-first activity tracking app that requires no account and delivers zero ads.

Built on innovative algorithms and rigorous mathematical principles, Urban Biker processes more than 75 statistics for every activity at sub-second resolution. Machine learning and robust statistical methods ensure physical and mathematical consistency across all metrics—maximum speed will never be smaller than average speed, and every data point reflects real-world physics. Advanced digital filters of proprietary design (IIR, FIR, non-linear) deliver superior accuracy and response, even on extremely steep terrain. Your raw data is available in CSV format for complete transparency and control.

Whether you're cycling, running, walking, car driving, or even flying, Urban Biker captures your complete activity profile. GPS automatically sleeps when you stop to preserve battery life, while adaptive GPS intervals reduce power consumption during slower movement. Physical activity recognition runs silently in the background, and barometric altitude combined with offline elevation data gives you precise vertical metrics. Energy breakdown reveals individual contributions from climbing, drag, and rolling resistance. Compute power from integrated sensors or let the app calculate it accurately based on your ride dynamics. AutoTerrain senses terrain roughness and adjusts power and energy consumption accordingly, while FenceGuard protects your privacy by hiding the location of your home or other sensitive places from recorded tracks.

Advanced sensor integration connects seamlessly with Bluetooth and ANT+ wireless devices, from power meters to cadence sensors, with automatic sensor selection and intelligent wheel circumference detection. Kinetic energy metrics show you the fall height equivalent of your current speed, helping you better perceive risk. Track braking energy loss and monitor brake pad wear. Resume any past track, set up multiple vehicle and activity profiles, and share your achievements directly to Strava or Google Fit.

Navigate with turn-by-turn directions—both visual and spoken—across more than 40 map types including Google, Mapbox, HERE, MapTiler, Thunderforest, and CycleOSM. Offline maps with terrain keep you on course without data, while animated weather radar and the Strava global heatmap help you discover new routes. Auto-zoom adjusts your map view based on speed.

Customize every aspect: create custom layouts, choose your colors and fonts, toggle between light and dark themes, and enjoy live 10-minute charts. Pocket mode keeps the screen off while in your pocket. Hand-wave controls dim or lock the display. Speech feedback, flashlight with automatic blinking, and AVAS acoustic alerts round out the experience.

Urban Biker is built from around 350,000 lines of original source code—the dedication and precision you deserve from a fitness tracking app that respects your privacy.
