Explore Syncing Biometric Data using APIs directly to PA

[casaout]

We'd like to explore including biometric data into the data captured by PA, stored locally and visualized in the retrospection.

Before I'll create a more thorough specification, can you please evaluate whether the APIs that Apple Health, Google Health/Fit and Garmin offer can also be used from a computer (i.e. not only the smartphone)? Because if yes, we could directly sync the data here, without having to develop a server too.

Apple:

• Can't access the HealthKit API outside of the Apple ecosystem (i.e. MacOS).

Google:

• Can access health data via the Google Health API. Features simplified data type bundles, standardised formats, auto-subscribing webhooks, HTTP and gRPC protocols, reconciled stream of data from all sources.

Garmin:

• Arguably the simplest one, allows access via their Health API. It uses a REST architecture and provides the data in a JSON format, however, you need access to the Garmin Connect Developer Program.

Other solutions:

• There are services which act as a bridge between all of the health APIs and provide a single entry point to the user, but they are all commercial and expensive, e.g. Terra and ROOK.
