Q: Guidance on setting up multiple data sources with the Health app without double counting.

Thanks

Have you got a link to more info on how it manages that? Would be interested to know which data source it chooses to use when.

Awesome thanks - will have a play with that tonight.

I have copied the key bits of info from the Web page you posted that answered my question.

Instead of adding similar data from different sources (like the steps from your iPhone and the steps from your fitness band), Health organizes and inputs data based on where it comes from. By default, Health prioritizes data in this way:

1. Health data that you input manually.
2. Data from your iPhone, iPod touch, and Apple Watch.
3. Data from other third-party apps and Bluetooth devices.

You can edit and rearrange your data sources to change the way that Health prioritizes data.

On the Share Data screen, tap Edit. Then touch and hold next to a data source. The data source that you place at the top will take priority over other sources that contribute that type of data.

Move the data source up or down in the list. To turn off a data source so that it doesn't contribute any more data for that category, tap the checkmark
