Basically! Is heart rate recorded to a Pebble specific app, or can it be synced with things like Apple Health?

I guess the one other feature I like of the Apple Watch is the rings/daily fitness goals functionality. I'll have to look into the Pebble more to see if that's possible. I also like the background monitoring features the Watch has (hypertension, etc.), but I'm assuming that's a little too much for the Pebble.

I believe you can see that stuff on the Pebble app but you can't sync with Apple health. See this previous pebble blog post: https://ericmigi.com/blog/apple-restricts-pebble-from-being-...

The Pebble 2 could write data to Apple Health ten years ago. It would be surprising to have that missing now.
