Meet the 3 pillars of sleep
Quality
Learn how much time you spend in each sleep stage: Light, Deep, REM & Awake. Deep sleep enables physical recovery while REM sleep helps with memory, thinking and creativity. Do you know how much time you spend in each ? Is it optimal ? Kira will help you improve and optimize these.
Duration
Circular looks at how much you have actually slept compared to your personal sleeping length needs. Circular also calculates the duration of disturbances during your sleep, and gives you a score on how efficiently you slept.
Circadian Rhythm
Science shows that sleep must follow a light/darkness cycle, be in line with your natural chronotype and that the more consistent you are with your sleep schedule, the better sleep you'll get. Kira makes recommendations that match up with your chronotype to achieve higher consistency.

Your Chronotype
Chronotypes are linked to your internal clock and to your genes. They have a direct effect on the timing of your daily activities and your performance in doing them. Discover your Chronotype and the optimal times to do your activities.
