Track your rides, runs, walks and fitness privately. No account required. No ads. 👉 Precise. 👉 Reliable. 👉 Feature-rich. 📈 Science underneath INNOVATIVE ALGORITHMS – machine learning and robust statistics algorithms are utilized for data processing. NUMBER CRUNCHING – more than 75 statistics computed for every activity in sub-second resolution, raw data available in CSV format. PHYSICAL CONSISTENCY – maximum speed cannot possibly be smaller than average speed, and metrics shouldn't spike without a cause. MATHEMATICAL CONSISTENCY – problems of decimal rounding, finite precision, or round-off errors are all handled very carefully for top accuracy. ✅ Ideal for sports and adventures With this app you can track all of your day-to-day activities, like walking and running, cycling, car driving, and even flying. 🛰️ GPS & Tracking • No data collected, no account required • GPS automatic sleep saves battery by turning off GPS when you stop • Adaptive GPS interval saves battery by using GPS less often when you're going slow • Speech • Automatic pause • Physical activity recognition • Barometric altitude (use barometer sensor) • Offline altitude (use elevation data from offline maps) • Energy breakdown: Examine individual contributions (climb, drag, roll, etc.) • Power from a power sensor, or accurately computed • Functional threshold power (FTP) estimate • AutoTerrain senses terrain roughness and adjusts power and energy consumption accordingly • Advanced digital filters of our own design (IIR, FIR, non-linear) for superior accuracy and response • Works accurately on extremely steep terrain • Reduce location noise • FenceGuard hides the location of your home or other important places from the recorded tracks • Bluetooth and ANT+ wireless sensors • Automatic sensor selection • Compass • Inclinometer • Automatic wheel circumference • Gear ratio • Kinetic energy: Shows you the fall height equivalent to your current speed, so you can better perceive potential danger • Braking energy: How much energy you lost by braking • Brake pad wear • Multiple vehicle and activity profiles • Resume any past track • Share to Strava, Google Fit • Can be used without GPS, e.g. for indoor spinning 🗺️ Maps & Navigation • Turn-by-turn directions to your destination, both visual and spoken • More than 40 map types, including Google, Mapbox, HERE, MapTiler, Thunderforest, CycleOSM, and others • Offline maps with terrain • Weather radar map, animated • Strava global heatmap with thousands of tracks from other users • Guide routes • Map auto-zoom depending on speed • Quick zoom buttons 🎨 User interface • Custom layouts • Custom colors and fonts • Light/Dark themes • Screen stabilization by suppressing small movements • Speech • Media controls • Live 10-minute charts • Dim and app-lock the screen by waving your hand • Pocket mode: Keeps the screen off while in your pocket • Screensaver with adjustable timeout and dim strength • Track color by parameter (altitude, speed, etc.) • Screenshot: Share the current app screen • Automatic or manual bell sounds • Automatic or manual moving sounds (AVAS, Acoustic Vehicle Alerting System) • Flashlight with automatic blinking • Derived temperature sensor ℹ️ Effort The application is built from around 350'000 lines of original source code. That's about 10x more lines than the famous three-volume fantasy novel.
