What is the Circular® Wake up score and how it is calculated

With the Smart alarm feature, the Circular ring can analyze your sleep cycles and wake you up at the best time to be alert and motivated as soon as you wake up.

Please read our previous article about The sleep stages that compose your sleep cycle. Basics n°3 about sleep first.

According to your movement, your heart rate variables and your temperature variations, the ring will determine in real-time in which sleep stage you are. Depending on the time window you have allowed the ring to wake you up, the ring will wake you up at the best moment. 

You'll be more or less alert depending on the sleep stage you wake up from.

The more you get into the deeper sleep stage, the more you can get sleep inertia that makes you feel disorientated or groggy when waking up.

The Wake-up score has been designed in the first place so that you can get feedback on awakening and alertness. Secondly, so that you can evaluate the efficiency of your smart alarm. Finally, it acts as a contributor to your Energy score (low weighting but still).

As with all Circular scores, a score equal or above 90 is Excellent, from 80 to 89 is Good and below 80 is Poor.

The perfect moment for you to feel refreshed is to wake you up at the beginning  of the light sleep stage. At this perfect moment, you will receive a 100 score. Then the score is built depending on the sleep stage during which you woke up, and also how far you were inside your stage.

Optimal (>90%): It was an ideal moment (during light or awake stage) for you to wake up alert.

Correct (80 - 89%): It's neither the best nor the worst stage (during REM stage). You may feel a little sleep inertia but not for long.

Poor (<80%): It was the worst stage (during deep stage) to wake up from. You may feel sleep inertia.

You’ll find your wake up score in the “Alarm clock” circle each time you wake up wearing the Circular ring. You can click on the score to get an explanation of the scoring.
