Yes! Apple Watch uses advanced optical sensors that provide reliable heart rate data for most indoor cycling activities. While a chest strap may offer slightly more precision during very high intensity intervals, the Apple Watch is more than sufficient for most Zwift riders.
Yes! YoBPM broadcasts as a standard Bluetooth heart rate monitor, so it works with any app that can connect to Bluetooth HRM devices, including TrainerRoad, Rouvy, and others.
