This article will show you how to broadcast heart rate from your Whoop 4. Whoop has become one of the most well-known brands in the fitness tracker industry because its stat tracking is very accurate and its design and materials don’t mess around. Its tracker, which doesn’t have a screen, can help you plan your workouts well and is great for people who care about recovery. You’ll need to set up broadcasting if you want to use its heart rate tracking to send information to other fitness trackers and services.
Let’s get this out of the way right away: the Whoop 4.0 is not a smartwatch. It’s also not something you buy outright, since you pay a monthly fee for the app and get the band for free. The non-display tracker can help you plan your workouts well and is perfect for anyone who is worried about recovery. But you need to set up this transmission if you want to use the heart rate measurement to feed other fitness trackers and services. Here’s how to broadcast heart rate from your Whoop 4.
What is Heart Rate Broadcasting?
Heart rate broadcasting is a feature that lets a heart rate monitor send its data to other devices, like fitness trackers, smartwatches, and smartphones. This lets people keep track of their heart rate in real time and share that information with other people. You can send out your heart rate using either Bluetooth or ANT+. The more common protocol is Bluetooth, but ANT+ uses less energy and can be used over longer distances.
To use heart rate broadcasting, you need a heart rate monitor that supports the feature and a device that can receive the data. Once the devices are connected, you can start sending out your heart rate. Heart rate broadcasting can be a helpful way to track your fitness progress, check on your heart health, and share your data with others.

Questions and Answers
Make sure the switch for HR Broadcast is on. After a WHOOP software or firmware update, this setting is sometimes changed. Remove the WHOOP from the device (Zwift, Wahoo, Concept2, etc.) and any other device it was previously connected to using the HR Broadcast feature.
WHOOP 4.0 is much better than WHOOP 3.0 at keeping track of workouts. You can’t tell the WHOOP Strap to start tracking a workout routine because it doesn’t have any buttons or a screen. You don’t have to, which is good news. Always remember that WHOOP checks your heart rate 100 times per second.
The study found that WHOOP is 99.7% accurate at measuring heart rate and 99% accurate* at measuring heart rate variability. This is more accurate than any other wearable in the study. Other wearables, on the other hand, had HR accuracy scores between 41% and 96% and HRV accuracy scores between 24% and 69%.
