How/when does the Apple Watch QZFitness companion app write the workout to Apple Health?

[HolgerLutz]

I stopped using the Apple Watch QZFitness app on my Apple Watch Ultra 1 because it completely drains my Apple Watch battery in less than 4 hours. Instead, I started monitoring my heart rate with the Polar H10 heart rate monitor and running the QZFitness app on my iPhone.

A negative side effect is that QZFitness no longer writes the workouts to Apple Health. As a workaround, I am now syncing the .fit files via the FitnessSyncer app, but I don't see the total steps being sent to Apple Health.

Does the Apple Watch QZFitness app sync the total steps to Apple Health?
Can I start the Apple Watch QZFitness app just before the end of a 4+ hour workout monitored on my Apple Phone and then stop it after the workout is finished, so it will still upload the complete workout to Apple Health?

@HolgerLutz let me understand: QZ on the watch in 4 hours drains the AW1 battery? on my aw7 it affects only the 5% in 1 hour! did you try to reinstall the app on the watch?
anyway for this kind of stuff i'm using the rungapp. did you try?
I also developed a special qz version that writes apple health without the apple watch, but let's see first if the rungap app is better for you

[HolgerLutz]

Thanks for the reply.
When using the Apple Watch QZ app, will it write the steps from the workout to Apple Health?
I recorded 6mins workout via AW QZ app that got written to Apple Health, but when going to Steps, nothing was added by QZ.

[HolgerLutz]

Rungapp seems to add the steps but not the QZ app (Apple Health -> Steps -> Datasources):

[HolgerLutz]

But maybe something was wrong with the test workout recording:

@cagnulein But in general, the steps should be synched to Apple Health?

[cagnulein]

yes i added them but in the new version.
send me an email to roberto.viola83 at gmail.com indicating this ticket and I will send you.

@cagnulein installed via Testflight, but AW QZ app only showing BPM data after starting - no values for the other metrics:
0 STP CAD.
KCal 0
Distance 0.00

I can now see 0 steps being synched from AW QZ app (Apple Health -> Steps -> Datasources), before nothing was synched.
So it seems to work, but do you have an idea why I get no other values beside BPM for the HR?

[cagnulein]

Do you see the steps on the qz main app enabling the tile? You can create a debug log so I can check it https://github.com/cagnulein/qdomyos-zwift/wiki/How-do-i-get-the-debug-log-in-case-something-doesn't-work%3F Roberto Viola Software engineer and open source enthusiast http://robertoviola.cloud Il giorno mer 5 mar 2025 alle 16:21 Holger Lutz ***@***.***> ha scritto:

@cagnulein yes, the step count tile is showing the steps.

I will check it ASAP thanks

[cagnulein]

got the issue. in order to fix it you have to disable the polar from the qz heart rate belt name setting. if you still need the polar as hr, just connect it to the watch directly in the bluetooth settings of the watch, and qz app on the watch, will use it instead of the optical hr sensor of the watch and also will save steps and everything

let me know

[HolgerLutz]

@cagnulein Thank you for looking into it and identifying the root cause.
It still doesn't seem to work properly, but I haven't had much time to check it yet. I will test it again tonight after work.

I fear the Polar HR Bluetooth connection to my Apple Watch Ultra was one of the factors responsible for the heavy battery usage, and I would like to avoid that. I'm fine using the workaround to manually upload the .fit file via Rungapp until FitnessSyncer hopefully fixes their current limitation/issue of the missing 'Steps' value sync.

You mentioned that there is a special QZ version that can upload the .fit file without using the Apple Watch?
That would be great to test/use as I don't want to rely on other sync apps for now.

ok so maybe i can try anyway to send data to the apple watch even if the polar is connected to qz if you want

You mentioned that there is a special QZ version that can upload the .fit file without using the Apple Watch?

yes it's the build 1015 on testflight, if you want i can send it and in case you can swap between them. in this case you have to remove the qz app on the watch in order to engage the trigger on the 1015 to write the apple health stuff without the qz app on the watch.

Let me know how would you like to proceed

[HolgerLutz]

If the 1015 build also contains the code changes needed for the Steps value to be correctly synced to Apple Health, I would prefer that as a solution and not having to use the QZ AW app - many thanks!

[cagnulein]

it doesn't actually but i can add it as well Roberto Viola Software engineer and open source enthusiast http://robertoviola.cloud Il giorno gio 6 mar 2025 alle ore 11:38 Holger Lutz < ***@***.***> ha scritto:

That would be great, but there's no rush – take your time.
I can use Rungapp for syncing in the meantime.
I already feel like I'm taking up too much of your valuable time with my small "issues".

[cagnulein]

I already did the code, i have only to test it. The problem is that i don't know when I will be able to :) I will let you know Roberto Viola Software engineer and open source enthusiast http://robertoviola.cloud Il giorno gio 6 mar 2025 alle ore 12:19 Holger Lutz < ***@***.***> ha scritto:
