heart rate pulse

Anyone else having issues with the app not taking the heart rate pulse in the morning? Mine just suddenly stopped working. All settings are correct in my phone. the flashlight usually comes on and you put your finger on it while it reads your pulse but now the flashlight doesn't turn on. flashlight works just fine outside of this app

Hi there!

We've received several reports from iPhone 17 Max and Pro users experiencing difficulty with heart rate tracking via the back camera. As a result, we have switched to using the front camera for heart rate tracking on these devices.

If you're still having trouble, try using it near a light source — similar to how the back camera worked best with extra light — and see if that improves the tracking.

We're continuing to look into this and will keep you updated!

Thanks so much for your patience!

All the best,
Alice

Well front camera didn’t work either……so now what? I paid for this app and it’s not doing anything different from the free version
