How to Choose

• Wearable vs non-wearable comfort: If you're a light sleeper or hate wristbands, choose under-mattress sensors like Withings or Beddit. For detailed sleep stages, wearables are more accurate.
• Subscription costs: Some trackers (Whoop, OURA) require monthly fees. Factor this into your budget – Fitbit and Withings have no recurring costs.
• Sleep stage accuracy: Wearables with accelerometers and heart rate (Fitbit, Whoop) offer better REM/deep sleep detection. Non-wearables like Nest Hub are less precise.
• Additional features: Do you want sleep apnea detection (Withings), heart health (Emfit), or a smart alarm (Nest Hub)? Pick based on your health priorities.
• Battery life and charging: Wearables need charging every few days. Non-wearables are plug-and-play. OURA ring lasts a week, while Nest Hub stays plugged in.
• Privacy and data sharing: Non-wearables don't track your body directly, but they need Wi-Fi. Check each brand's data policy, especially for cloud storage.
