Wird auch beim Edge Explore 2 nicht erkannt

Hallo lieber HRM Team, nachdem ich zunächst keinen Erfolg mit der Anzeige der Herzfrequenz auf dem iPhone und der Apple Watch hatte, ist es mir jetzt gelungen, die Funktion zum laufen zu bringen. Der Edge Explore 2 ist nun da, koppelt aber nicht. Möglicherweise ist mein Probeabo heute ausgelaufen. Liegt es daran? Der Preis an sich ist fair. Aber: Ich möchte ungern für etwas bezahlen was nicht funktioniert.

Tönt nach einem Problem zwischen Apple Watch und iPhone 🤔 Auf der Watch wird die Herzfrequenz denn angezeigt? Wenn nein: Start drücken und kuez warten — danach müsste es auch auf dem iPhone sein. Beste Grüsse Dominik

Funktioniert nur manchmal

Die App funktioniert leider nicht wirklich.
Wenn sich der Sensor überhaupt verbindet dann nur nachdem dem vorherigen ent- und wieder gekoppeln (teilweise brauchte ich 5 Versuche).
Und nur weil sie dann verbunden ist heißt es nicht dass es auch so bleibt, hat sich leider während der Fahrt wieder verabschiedet.
Ich kann die App leider nicht weiterempfehlen.

Freut mich zu hören! 😊 Beste Grüsse Dominik

Vision is there.

Unfortunately does not work with Magene 606v2 or 506se for now but the vision is there

Doesn’t work with Hammerhead 3

The HR is shown on my Apple Watch but isnt send to the hammerhead 3. There is always a HR of 0

Response from developer

Hi, If this happens, you have to press „Cancel“ on the bluetooth permission request that‘s shown on the iPhone. I personally use the app with my Karoo 3 and know that this is a bit confusing. Best regards, Dominik

FAQ

What does the HRM Heart Rate Monitor app do?

This app allows you to use your Apple Watch's heart rate sensor to transmit data to compatible cycling computers via Bluetooth Low Energy (BLE). It acts as a bridge, sending your heart rate from your wrist to your bike computer without requiring any extra hardware like a chest strap.

What are the key features of this app?

The app's main features include connecting your Apple Watch's heart rate sensor over BLE, sending this data to any BLE-equipped bike computer, and working seamlessly with your iPhone without needing to carry it. It also reads data from the Health app and provides a simple, reliable alternative to traditional heart rate monitoring solutions.

How much does the HRM Heart Rate Monitor app cost?

This is a paid app that requires a subscription. However, it offers a seven-day free trial period. If you decide not to continue after the trial, you can cancel before it ends to avoid being charged.

What devices is the HRM Heart Rate Monitor app compatible with?

The app is compatible with almost any BLE-equipped bike computer. You can find an up-to-date compatibility list on the developer's website at https://dominikmaglia.com/hrm-app-user-guide/#device-compatibility. It requires installation on both your Apple Watch and your iPhone to function.

Can I use my Apple Watch heart rate data for other fitness activities?

While this app specifically focuses on transmitting heart rate data to cycling computers, it reads your heart rate data from the Health app. Your heart rate data is stored securely within the Health app, which can be used for various other fitness tracking purposes on your Apple Watch and iPhone.
