Sleep Tracking Accuracy
How sleep is tracked: Using methods developed with Stanford researchers, movement and other data from your watch are used to determine when--and how deeply--you’re sleeping.
What affects accuracy? You’ll need to wear your watch while sleep to track sleep, but a few other factors can affect accuracy:
Movement: detecting how much you’re moving is a big part of determining you’re asleep, so if you’re unusually active in the middle of the night, sleep data may be thrown off
Battery life: Make sure to stay charged up! Pebble batteries last for days, but if you run out of power in the middle of the night, you won’t get complete sleep data
Sleep tracking on Pebble smartwatches is intended to provide you with information to encourage a healthy lifestyle. Pebble devices rely on sensors that track your movement and other metrics, and the data and information provided is intended to be a close estimation of the metrics tracked, but may not be completely accurate.
The sleep data is not intended to be used for medical purposes, nor is it intended to diagnose, treat, cure or prevent any disease or condition.
