WearCompare

Overlay sleep records from multiple wearables. Export records for personal offline use, or send to a friend.

WearCompare is a beta application that reads sleep, heart rate, and related health data you have authorized through Apple Health (HealthKit), and displays summaries, hypnograms, and side-by-side comparisons of that data across the wearable sources you use (for example, Apple Watch, Oura Ring, and Garmin devices). The app also allows you to export a personal copy of your Health data as CSV or JSON files via Apple's share sheet.
