📈 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

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.
