Pomodoro, but timed to your body.

Dr. Michael Breus, clinical psychologist and sleep specialist, developed the Lion / Bear / Wolf / Dolphin framework used in our quiz — grouping people by when their body and brain naturally want to work, not by willpower or habit. It's the foundation of The Power of When.

Daniel Pink's When synthesizes over 700 studies showing that time of day explains roughly 20% of cognitive performance variance — about the gap between a good and bad night's sleep.

Chronobiologist Till Roenneberg demonstrated that chronotype is largely genetically determined and that mismatched schedules create “social jetlag” — a measurable drag on health and performance that affects the majority of working adults.

Perhaps most counterintuitively, research shows that creativity peaks during recovery, not peak hours. Mental fatigue loosens cognitive constraints and enables unexpected connections — meaning the best time for creative work is often when you feel least “sharp.”

Using Pomodoro apps, I kept feeling like I was forcing myself to fit the clock. Little by little, it felt less and less like me — until I stopped using them altogether.

Then I came across research on how focus rises and falls with each person's own time of day, and I wanted to bring that into a Pomodoro app. My hope is that Mureut helps you build days that feel like yours.
