My SmartSleep score versus another device's results
If you wonder why your SmartSleep results may differ from the those of other sleep metric devices, please find here if we can answer your questions.
Why do my SmartSleep and other sleep monitoring devices say that I slept different amounts of time?
Your SmartSleep uses an advanced method for determining your sleep, similar to the equipment used in a clinical sleep lab. Much like a heart rate monitor monitors your heart beats, the SmartSleep is measuring precise sleep data from your brain while you sleep. Most other devices are not a direct monitor, they are monitoring from a distance or with different metrics and therefore you are getting a variation in the measurement of your sleep data.
