Question: Export of Apple Health Data
I have a Polar H10, that I have enabled as a health device on Apple Watch. All running the newest versions of WatchOS/iOS 11.3(15E5201e)
I receive updates every second that I can verify that the communication is working as expected.
I wear the polar device which keeps heart rate updates through the night and day. So there will be close to 80k entries for only heart data.
If I navigate to iPhone Storage 799 MB is currently allocated by the health app
When I perform the export, it takes about 5+ mins and a 22 byte export.zip file is created.
I have attempted to save to local and still get the 22 byte file. FWIW 22 bytes is the header information of a ZIP file, so the file is empty.
A few notes.
- I want to export all of the content, there are several apps in the store that allow access to export mins or hours. I need the detailed granularity of per second usage
- This has worked before when there was less health data using the exact same method
