How to Choose

  • Budget and subscriptions: Some trackers have upfront costs plus monthly fees. Factor in the total cost over a year.
  • Accuracy needs: For detailed sleep stages, go with a wearable like Fitbit or Oura. For basic sleep time, an app may suffice.
  • Battery life: If you dislike charging, choose Garmin or Whoop. Apple Watch needs daily charging.
  • Integration: Check if the tracker works with your phone (iPhone vs Android) and any other health apps you use.
  • Extra features: Some trackers also monitor stress, heart health, or snoring. Pick based on your priorities.
