Cadence is 100 times simpler and 100 times more useful than the other big riding apps like rouvy and zwift. Instead of most of my tiny phone screen being taken up by a tiny virtual cyclist and barely visible confusing metrics, Cadence allows you to see everything you need on one screen: heart rate, speed, distance, and cadence. It connected quickly and easily to both my Garmin cadence and speed sensors. It also quickly syncs data to both Strava and Apple Health. If you have an indoor bike, this is by far the best app out there for effectively and easily tracking your exercises and progress. And bonus: you can take it on outdoor rides and runs too.
