About this app

Track your rides, running, walking and other fitness like a pro. Simply track anything. No data collected. No ads.

👉 Reliable.
👉 Feature-rich.


✅ 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.


📈 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.


🛰️ 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 More info

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.

Ratings and reviews

I used to use a bike computer and pocket my phone. When I found this app the revelation of having your phone do everything a separate computer does (and more) was life changing. In addition all your phone functions right at your fingertips. This app is freaking amazing. Far more features than you could ever get on a bike computer and 10x the processing power. Next Step - Record rides on your phone with heads up display for playback later. That would be AWESOME.

Updated review: best cycling app. Period. I connected a Bluetooth cadence, speed/distance, and heart rate sensor (3 separate sensors) all at once, but you don't need any sensors to get speed and distance as you can rely on GPS if you get good GPS reception where you ride. Tons of features, basic features are intuitive but you can deep dive into more complicated stuff . . . Does more than you think at first glance. Tech support is top notch. Buy the license to support these folks!

Just installed and getting it set up. I live in the US so the first change was to update the units, as I read from other reviews it is set up on the metric system by default. As one reviewer mentioned, finding this setting takes a bit of hunting so let me help. The path to update this is Settings>Display>Units. Once there, you can toggle btw imperial/metric for all of the settings like distance, speed, weight, etc. Haven't used yet so I will update my review after several rides.
