Sleep Tracker Buying Guide – Key Features to Consider

Sleep Stage Tracking

Look for devices that can differentiate between light, deep, and REM sleep stages. More advanced trackers can identify when you’re in each stage with reasonable accuracy.

Importance:

Battery Life

For wearables, look for devices with at least 5 days of battery life. For non-wearables, consider if they require batteries or plug into an outlet.

Importance:

App Quality

The companion app is crucial. It should provide actionable insights, not just data. Look for sleep score systems, trends over time, and personalized recommendations.

Importance:

Comfort & Design

For wearables, comfort is essential since you’ll wear it while sleeping. Consider size, weight, and material. For non-wearables, consider installation requirements.

Importance:

Health Metrics

Beyond basic sleep tracking, many devices monitor heart rate, breathing rate, blood oxygen, and skin temperature. Consider which metrics matter most to you.

Importance:

Price & Subscription

Consider both upfront cost and potential subscription fees. Some devices require monthly subscriptions to access advanced features and detailed data.
