We supported it before, should be pretty straightforward to support now.

Being able to sync steps taken, heart beat, and especially sleep tracking with Apple Health would 100% push me to Core Time 2.

Presumably the same as the original Pebbles, which were able to feed step data and HR data into the Apple Health app.

Google Health Sync as well?

And I'll be looking for Vitality integration for my employer's health program!
