Can i know my circadian rhythm by using this app?

The chronotype Raven button feature show all the old sleep that happen in the past, and can I use that data to know my circadian rhythm accurately?

Hi @Sleepformuscle, the app works with two chronotypes - the lark and the owl.
Each chronotype also has 5 levels.
Your chronotype estimated from the sleep history in the app is shown in the Left ≡ menu as an icon; more data is available in your Charts, in the Chronotype tab.
