## What is HeartBLE?

Broadcast your heart rate from Apple Watch directly to apps and training gear. Connect via Bluetooth as a heart rate monitor to:
- your Mac, Apple TV, iPad (running Zwift, MyWhoosh, Rouvy, ...)
- PCs
- Bike computers (Wahoo Element, Garmin Edge)
- Training equipment
- Anything that supports a chest strap

FEATURES
- Direct watch to device connection, no intermediate phone: less friction & reliable.
- Universal Compatibility: standard HR BLE protocol.
- Stays active while workout is running.
- No ads, notifications, tracking or third-party analytics. Your data stays on your device.
- Quickly open from the watch face with a complication.
- Start/stop from Control Center.
- 7-day free trial, then single-time purchase. No recurring payments.

USAGE
Enable Bluetooth and Health access – that allow HeartBLE to listen heart rate data from Apple Watch and broadcast it via bluetooth. Pair your device as usual, by selecting your device in the Bluetooth menu. It will either show your Apple Watch name, or "HeartBLE". Then, tap "Start" – your device will receive the heart rate every second. As you finish, tap "End" - that will discard the workout and save your Apple Watch battery. 

Here are a few tutorials on how to connect HeartBLE to third-party apps.
- Strava on iPhone: open Record tab > open bottom panel (pull the handle up) > Add a sensor > select your device name > Done.
- Tacx Training: Settings > Device Manager > Other Devices > HeartBLE.
- Zwift: Let's go > select activity type > Heart Rate > pick your device > Close.

Other supported apps & devices: MyWhoosh, Rouvy, Peloton, TrainerRoad, MapMyFitness, Wahoo, Garmin, Precor, Mirror, LifeFitness, NordicTrack, iFit, Concept 2 and more!

Pro tip: you can connect your Apple Watch to multiple devices.

Note: this app can't be used simultaneously with other workout apps – new workout will abort the previous one!

STORY
I'm an amateur cyclist: I ride for joy on various types of bikes. Sometimes compete in XCO, XCM and take brevets. This winter was snowy – good time to put my bike on a trainer, and pay attention to numbers: power, heart rate. However, the strap of my old heart monitor started to crumble because of time and sweat. I wanted to buy a new one... Then I realized that I always have a heart rate sensor on my Apple Watch. Why not put this to use? First, I made some market research, but unfortunately all the apps require an intermediate iPhone. This is inconvenient and too much of a load for the phone's battery, since I use it as a hotspot for my MacBook, which runs Zwift or Tacx. Thus I set the goal to create the app that sends heart rate from Apple Watch to my Mac directly. Additionally, competitors' apps were irritating: they forced me to watch ads before workout, or turned off during the sprint because the free workout duration was limited. So in my app I offer a comfortable trial period that allows you to try it fully before you decide whether you need it.

TLDR: I built this app for myself, and I'm glad to share it with you.

### 4/5 — Works great with Apple Watch Series 9 and iGPSPORT BSC100MAX, but needs automatic reconnection

*2026-08-13*

I’m using HeartBLE with an Apple Watch Series 9 and an iGPSPORT BSC100MAX.

The app works very well overall, and I’m able to display my Apple Watch heart rate on the BSC100MAX.

However, the next day, when I started HeartBLE on my Apple Watch and turned on the BSC100MAX, the heart rate sensor was not recognized.

I then went to the pairing screen on the BSC100MAX and selected HeartBLE again, and it was recognized normally. After that, it worked without any problems.

It would be even better if HeartBLE could automatically reconnect to the BSC100MAX when starting up.

I look forward to future updates

This connected as a heart rate monitor to my NordicTrack RW500 rowing machine perfectly. Works well, broadcasts heart rate as expected, and now I can focus on the device screen.
