Sleep Tracking

Titanium smart ring with research-grade sleep tracking — HRV, heart rate, blood oxygen, skin temperature, and sleep stage detection. 5–7 day battery life. The most unobtrusive sleep wearable.

Continuous HRV and strain monitor that quantifies sleep performance, recovery, and training readiness. Journal feature lets you A/B test habits (supplements, alcohol, screen time) against your sleep data.

Under-mattress sensor pad with clinical-grade sleep apnea detection. Tracks sleep cycles, heart rate, snoring intensity, and breathing disturbances. No wearable required — just place it under your mattress and forget it.

The current-gen Apple Watch Ultra with a new sleep score, hypertension notifications, 5G connectivity, satellite SOS, and the longest battery life Apple has ever shipped in a watch. Clinical-grade sleep staging, blood oxygen, wrist-temperature trends, and HRV feed directly into the Health app. Doubles as a serious training computer — the strongest single-device choice for people who want sleep and fitness in one.

Apple's mainline smartwatch for people who want the health and sleep tracking without the Ultra's ruggedized size or price. Series 11 adds hypertension notifications, the new sleep score, refined HRV and wrist-temperature trending, and always-on 5G. Better fit for sleep tracking than the Ultra thanks to the lighter case, and still pulls everything into the Health app for long-term trend analysis.

Garmin's dedicated health and fitness smartwatch with advanced sleep scoring, Body Battery energy monitoring, HRV tracking, and nap detection. 14-day battery life crushes Apple Watch for people who don't want to charge daily. Sleep Coach feature recommends optimal bedtimes based on your data.
