- Change various bundle IDs and permit HealthKit access for the bundle ID. You’ll need a paid Apple Developer account in order to do so.

- Build HeartRateRPC and run it on your Mac. It will use MultipeerConnectivity.
NOTICE: If you unironically use this, please reconsider using it. It’s never okay to needlessly give away private information.
