Hi there! I understand that SleepWatch isn't recording your sleep properly when you’re using your CPAP machine. I’d like to get a bit more information to help you effectively.

- Are you wearing a smartwatch or using SleepWatch solely on your phone while sleeping with the CPAP?
- Does the app fail to track any sleep at all, or does it record incomplete or inaccurate data?
- Have you noticed if SleepWatch records sleep normally on nights when you don’t use your CPAP?
- Also, do you have the app’s permissions set properly to allow sleep tracking and health data access?

This will help narrow down whether the issue stems from data syncing between devices, permission settings, or something else related. Let me know!

It records incomplete or no sleep data. I wear an Apple Watch and it is connected to Apple Health. I always use the CPAP machine at night.

Thanks for sharing those details. Since you're using an Apple Watch connected to Apple Health and always use your CPAP machine, the issue might be related to how SleepWatch interprets or receives data when the CPAP machine is in use.

Here’s a good step-by-step approach to troubleshoot this:

1. Check Permissions in Apple Health:
Open the Apple Health app on your iPhone > Tap on “Data Access & Devices” > Select “SleepWatch” > Make sure all toggles for data access (read and write) are turned ON. This ensures SleepWatch can fully access your sleep data from the Apple Watch and Health app.

2. Enable Sleep Tracking on Apple Watch:
On your iPhone, open the Watch app > My Watch tab > Open the Sleep section > Make sure “Track Sleep with Apple Watch” is enabled. Also, verify “Wrist Detection” is turned ON under Passcode settings. These settings help Apple Watch collect continuous sleep data.

3. Wear Your Watch Properly Overnight:
Confirm you wear your Apple Watch snugly on your wrist while you sleep with the CPAP machine. Sometimes if the watch is loose or removed during the night, it may fail to record full data.

4. Restart Devices & Update Software:
Restart both your Apple Watch and the paired iPhone to refresh connections. Also, check that both devices and the SleepWatch app are updated to their latest versions.

5. Review SleepWatch App Settings:
Open SleepWatch on your iPhone > Go to settings and ensure no special mode disables tracking when CPAP usage is detected. If possible, try manually entering a sleep session and see if it saves properly.

6. Consider Potential CPAP Interference:
Though rare, the CPAP machine’s mask or airflow might affect the watch sensors slightly. If the above steps don’t fix it, try using SleepWatch on nights without the CPAP briefly to see if you get complete data. This helps confirm if the CPAP usage is directly causing the missing data.

These steps often solve incomplete sleep recording issues when using Apple Watch and SleepWatch together with CPAP. If you want, I can guide you through any step or check the app’s specific help article on “not enough data” issues for more insights1 2.
