HeartBLE: Heart Rate Monitor1.7 - App Store

Broadcast your Heart Rate from Apple Watch to training apps and gear! Connect via Bluetooth as a Heart Rate Monitor to:
- Your Mac, Apple TV, iPad (Zwift, MyWhoosh, Rouvy, ...).
- Bike computers (Wahoo Element, iGPSPORT, Magene, ...).
- Training equipment: treadmills, gym gear, indoor cycling trainers and rowing machines.
- PCs, smart TVs with training apps (Zwift, MyWhoosh, Rouvy, ...).
- Anything that supports a chest strap.

FEATURES
- Direct watch-to-device link, no intermediate phone: less friction, more reliability.
- Universal Compatibility: standard HR BLE protocol, widely adopted and supported.
- Resilience: recovers after disconnects and Bluetooth issues, even during the most intense workouts.
- Simplicity: one tap and done. No workout recorded on the watch, no clutter - the receiver is your single source of truth.
- 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
1. Enable Bluetooth and Health access - that allow HeartBLE to listen to heart rate data from Apple Watch and broadcast it via Bluetooth.
2. Tap Start. HeartBLE would enter the Discoverable mode.
3. Pair your device as usual, by selecting HeartBLE in the Bluetooth menu. It will either show your Apple Watch name, or "HeartBLE".
4. As you finish, don't forget to tap End - that will discard the workout and save your Apple Watch battery.

SETUP
Connect HeartBLE to third-party apps:
- Zwift: Let's go > select activity type > Heart Rate > pick your watch > Close.
- MyWhoosh: Enter your profile > choose activity type > connect power source first > click Heart Rate banner > select your Apple Watch name from the list.
- Tacx Training: Settings > Device Manager > Other Devices > HeartBLE.
- Strava on iPhone: open Record tab > open bottom panel (pull the handle up) > Add a sensor > select your device name > Done.

... and devices:
- BSC100S: Enter E3 mode by pressing the right button, press the left button, and wait until heart rate appears. During the pairing you may restart HeartBLE if it's not detected right away.

TROUBLESHOOTING

- "Purchased" on App Store.
The app shows "Purchased" on your iPhone because it's Apple Watch only. That doesn't mean you spent any money - it merely indicates that you tapped "Get" before. I recommend opening the App Store on your watch, searching for HeartBLE, and downloading it there.

- I can't complete Free Trial or Premium purchase.
If this issue appears, I recommend relaunching the app:
1. Double-press the watch crown
2. Swipe HeartBLE left in the list
3. Tap X
4. Start the app again
It may take several attempts, but you should finally be able to complete your purchase.

- App is kicked off when I start another workout.
This app can't be used simultaneously with other workout apps on the watch - new workout will abort the previous one!

- Bicycle computer forgets the HeartBLE.
- I pair it again and the second "HeartBLE" appears.
For your privacy, the Apple Watch rotates the Bluetooth address; it helps to prevent tracking. Some bicycle computers do not support address rotation, so you would have to pair them again after you reboot your watch or relaunch the HeartBLE.

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

Version History - Greatly improve Help section in Settings: more help topics are available directly on your watch.
- HeartBLE is even more resilient! If an on-device Bluetooth issue occurs (for example, if Bluetooth is turned off or something fails), it will automatically retry and recover.
- Translated on Chinese, German, Spanish, Japanese and Italian! 1.7 Sep 30 - Fixed bug when Free Trial and Premium purchases weren't able to complete.
- "Tip the Developer" section in Settings is now hidden from non-premium users to prevent confusion. Some of them thought that it would unlock the app. If you are a Premium user, and you like this update, you could support the continuous improvement of HeartBLE by leaving a tip.
- Updated highlight improved. 1.6 Aug 17 - Fixed critical bug when the subscriber wasn't notified when the app went off screen. If you had disconnects before, this might be the reason. Please, check how the app runs now, and update me: heartble.sup@gmail.com.
- Reduced delay before the first heart rate reading from 5s to 0.5s!
- HeartBLE doesn’t contribute to Activity Rings anymore!
- HeartBLE wouldn't save workouts anymore, existing workouts would be cleaned. If you wish to track a workout, then the intended way to do it is on the receiving side. 1.5 Jul 1 - Familiar connection: Your watch now reconnects to your bike computer or favorite apps automatically when you start a workout — no need to select it again.
- Persistence: Apps can now recognize your watch correctly, no multiple entries anymore.
- Stronger reconnection: If the connection drops, the app will try to reconnect, even if you’ve moved away briefly.
- Added Settings menu. 1.4 May 21 - Fixed connection issues with the ROUVY app.
- Resolved Bluetooth connectivity problems with some third-party iPhone apps.
- Reduced battery usage by disabling Bluetooth service advertising (discovering) when already connected to a device.
- Improved visual status highlighting.

Note for bicycle computer users:
I'm aware of connection issues affecting some Garmin Edge and other bike computer models and am actively working on improvements. In the meantime, you can try:
- Restarting your bike computer
- Disabling Bluetooth and the Garmin app on your iPhone 1.3 May 10 - Improved main screen, added "outer glow" status indicator.
- Fixed rare crash during Health permissions request.
- Trial now displays remaining days and hours.
- Fixed bug with endless trial. Sorry, dear users, I need to make money ;) 1.2 May 3 I want to dedicate this version to the rowers and cyclists who enrolled in the tester program and shared their precious feedback. Without you I'd never know how the app works with Wahoo Element or rowing equipment. The bugs you found and ideas you shared would greatly improve the app.

In this version:
- Bluetooth now is only starts when the workout is running. This improves battery health and prevents spamming 0s to your equipment.
- Added a watch-face shortcut: complications, allowing one to quickly open the app.
- Added Control Center toggle allowing one to quickly start/stop the workout.
- Reduced amount of data in the workout session: no cycling or walking distance or energy anymore. Less clutter in your data, only the heart rate is processed.

More updates pending! 1.1 Apr 24 1.0 Mar 5
