Real reviews from the App Store
Finally! An app which allows the Apple Watch HRM to be used with other apps, such as Zwift and Biketerra. Consistently! Well done to the developer.
This made my dream of using my Apple watch for heart rate in Zwift come true!
Works flawlessly with myWhoosh, every other app I have tried doesn't show up for some reason. And shout out for having a purchase option, I hate subscriptions โค๏ธ๐ด
I found your app on Reddit after getting a smart bike trainer to use on Zwift. I couldn't figure out how to get my Apple Watch to connect to Zwift for the life of me but this app saved me after scrolling through multiple articles and subreddits. Worth every penny!!
I usually use the companion app on my phone to link my Apple Watch to Zwift, but this app also does it for Bitgym and (presumably) lots of other similar apps on my iPad and gym equipment. Works smoothly - well worth it to avoid needing a separate heart monitor when Apple Watch is not natively linked.
Everything you need to know about YoBPM
YoBPM works with Apple Watch Series 4 and newer running watchOS 10 or later. This includes Series 4, 5, 6, SE, 7, 8, 9, 10, and Ultra models.
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.
The Apple Watch reads your heart rate but cannot directly broadcast Bluetooth to other devices. The iPhone app receives the heart rate from your watch and broadcasts it as a Bluetooth heart rate monitor that Zwift can connect to.

Your iPhone needs to be within Bluetooth range of both your Apple Watch and the device running Zwift. We recommend keeping your phone near your trainer setup for the best connection reliability.
YoBPM is optimized for efficiency. During a typical 1-hour ride, expect about 10-15% battery drain on your Apple Watch (similar to any workout) and minimal impact on your iPhone battery.
