How is Sleep Quality calculated?

Sleep Cycle’s Sleep Quality is affected by two factors:

* Sleep quantity
* Frequency of movement

In short, the more you sleep and the less you move, the higher Sleep Quality you will get.

Sleep Quality will be calibrated the first nights using Sleep Cycle, and the value will be more and more accurate over time.

We are currently researching the next version of Sleep Quality, with factors such as waking up in the middle of night, % deep sleep, number of sleep cycles etc. affect the value.
