Best HRV Monitors & Devices

Best for serious athletes who want completely passive tracking and don't mind paying monthly. The training load and recovery insights are excellent, but you're locked into their ecosystem.

Best for those who prioritize comfort and discretion. The ring form factor is unmatched for sleep tracking, though the optional subscription is frustrating for a premium hardware purchase.

The accuracy benchmark. If you want the most precise HRV data and don't mind taking deliberate morning readings, the Polar H10 paired with a good app is hard to beat. Best value for serious tracking.

Convenient if you already wear one, but not recommended as a primary HRV device. The native Health app provides basic overnight HRV data, but dedicated devices offer much better insights.

Great for athletes already in the Garmin ecosystem. Recent models include solid HRV tracking, though features vary significantly across the lineup. The multi-week battery life is a major advantage.
