Thanks for reaching out. When you have two Apple Watches, Apple Health automatically collects data from both, consolidates it, and prioritizes one source based on the settings you’ve configured in Apple Health.

That consolidated data is what Sonar receives, so what you see in Sonar should match what’s in Apple Health. Are there any specific metrics where you’re noticing a mismatch?

One thing worth checking: navigate to the Synced tab in Sonar, tap Apple Health → Customize, and you’ll see a pop-up where you can prioritize which watch should take precedence for sleep and workout data.

Happy to clarify further if needed — just let me know.
