U Biker: GPS Tracks

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.
