What to Look for in a Sleep Tracker?

Buying the best sleep trackers are more complex than just purchasing a watch. To find one that’s right for you, you need to start with the data the device delivers when tracking your sleep and activity. You’d then want to look at how the data is presented. Does it have an app? Does it use special software? From there, you can sort out what features are going to be most useful to you.

Common Sleep Tracker Features

The best sleep trackers will typically have some or all of the following features:

  • Heart Rate Monitor
  • Accelerometer
  • Body Temperature
  • Humidity
  • Bluetooth

Depending on the make and model, a sleep tracker may also record:

  • Pulse Oximeter
  • Glucose
  • Blood Pressure
  • UV light
  • Ambient Light Sensor
  • ECG
  • Brain Wave Monitoring

If you’re primarily concerned about your sleep, you’ll want a sleep tracker that measures your cardiac functions. This can include heart rate, ECG, or blood oxygen levels.


Wearing a sleep tracker on your wrist holds the key to providing insightful data on your sleep stages, nightly movement, and the time you spent asleep, awake, and in REM sleep. Sleep trackers also translate into everyday life by including data on your stress levels, fitness statistics, and information on the number of calories you burned. An added bonus? Sleep trackers often have smartwatch capabilities, so you can keep up with your notifications such as calls, texts, and calendar events all in one place.

The best sleep trackers are an all-encompassing combination of the time you spend asleep and awake.
