Try Apple Watch with AutoSleep app

What to Do

Wear your Apple Watch to bed and install the AutoSleep app ($5.99, one-time purchase) for detailed sleep analysis beyond Apple's built-in tracking.

Why It Works

AutoSleep achieves 92% accuracy compared to professional monitoring for HRV measurements. It provides deep metrics including sleep quality rings, heart rate dipping, and sleep bank tracking. For existing Apple Watch owners, it turns hardware you already have into a capable sleep tracker.

Tips

• Best for: people already in the Apple ecosystem who don't want another device
• Limitation: tends to overestimate deep sleep compared to EEG validation
• Battery management is the main challenge — charge during your evening wind-down routine
• Apple's built-in sleep tracking is simpler but sufficient if you want zero setup
