If you’ve ever uploaded a ride or run from Cadence to Strava and noticed a strange “sawtooth” pattern in your speed graph, here’s what’s happening behind the scenes. Cadence records both speed and distance once per second. The speed values come directly from GPS or connected speed sensors—they’re instantaneous, accurate, and smooth. The distance values […]
Cadence reports elevation directly from your phone’s GPS chip. GPS uses a global model of the Earth called WGS84. Because the Earth isn’t a perfect sphere, this model doesn’t always match “sea level.” The difference between WGS84 and sea level can vary depending on where you are in the world, and it’s normal to see […]
No two apps or devices will ever report identical numbers. Each one samples, filters, and smooths raw data—GPS, barometric, sensor, and timing data—using proprietary algorithms. Those algorithms are not public and vary in how they handle missing data, noise, and rounding. Even two identical devices riding side-by-side and uploading to the same service will log […]
For iPhone, Android, or “With iPhone” Apple Watch Based Workouts If you have a power meter Cadence uses that as it’s by far the most accurate way to estimate calorie burn. Otherwise, Cadence uses MET values with adjustments made for grade. Cadence doesn’t currently calculate based on heart rate because testing has shown it to be wildly […]
Cadence counts running cadence like cycling cadence, so one foot is one revolution, rather than each foot individually. That’s how devices like Garmin and Polar do it, but apps like Apple Workouts and Runkeeper count each foot individually, which would be double what Cadence shows.
If the Strava App opens during authorization If you have the Strava app on your phone and it opens when trying to authorize Cadence, please remove the Strava app and try again. Doing so will force authorization to happen on Strava’s website instead, which should work correctly. After you’ve authorized Cadence, you can reinstall the […]
