It sounds like you have a difficult wrist for the watch to get a reading. It is worth checking Apple's suggestions for how to improve things (https://support.apple.com/en-us/HT207941#heartrate) but a few people just cannot get on with Apple's sensors for some reason (veins a long way below the surface, tattoos etc).Hi, after using a Garmin product nearly a year I'm back with a Apple Watch 6 and using your App for running.
Unfortunately I think I have the same issue like back in the days with my Apple Watch 4.
After starting the app and starting to run, it takes approx. 4-6 min. time to show the heart rate. Sometimes it shows a fixed heart rate for nearly a few minutes until it works fine.
1) I tried to switch to pause mode immediately after starting to wait for the heart rate to be immediately exit the pause mode when HR is displayed. Unfortunately that also takes a few minutes.
2) At the same time I tried to switch to the WatchOS Heart rate app during the pause mode, but that app also takes just as long there until the HR is in the official HR app displayed.
Do you have an idea for my issue? thanks in advance...
Edit / wish:
At the same time as GPS signal is displayed as available, the heart rate should also be displayed as available in the initial image (where the sports can be selected or in the "Open Workouts" screen).
Some people who find this, such as @andrewstirling, use an external HR monitor instead (which the app will use automatically if paired with the watch). Some of them only use an external monitor in the colder months and can get by in the warmer months, but a few people need it all year round.
I would love to show the HR in the main menu alongside the GPS signal. However Apple only allow some apps to get frequent HR updates outside of a workout. Developers need to request access, which I have done many times to no avail. I never hear back from them.
In some ways it may be a good thing because the fact that the app uses the GPS outside of a workout is causing a few people issues with watchOS 7 (the app never seems to go away and needs to be force killed), so using the HR outside of a workout may cause similar problems.
