This tag collects CellularNews articles about sleep tracking features on wearable devices, specifically for readers who use Fitbit or Garmin fitness trackers and want to understand how their sleep data works. Whether you are trying to interpret a new score, troubleshoot a missing reading, or decide what a specific sensor or mode does, these pieces are written for the everyday phone and wearable user who wants clear, practical answers.

The articles solve two main kinds of problems. First, they help you understand and interpret the sleep-related metrics your device provides. You can learn what terms like "Body Battery" on Garmin or "Sp02" on Fitbit actually mean, and how Fitbit determines when you are asleep. Second, they address common frustrations with missing or confusing data, such as why you are not getting a Sleep Score on your Fitbit, or what the Stress Management Score is supposed to tell you. A few articles also cover hardware and software changes, like what the Fitbit Inspire 3 does, how accurate the Fitbit Charge 5 is, and what a major Fitbit app update looks like.

Overall, these articles help the reader take a confusing number or setting and turn it into a useful insight about their rest. They explain what a feature does, why a reading might be absent, and how to make sense of the sleep data your wearable collects every night.
