It lives on your health data.
Reads how you actually slept and moved, then tells you the truth about it every morning. No logging. No pep talks.
A creature that ages faster than you when you neglect yourself.
What Nularo does
Reads Apple Health for you
Sleep, sleep stages, steps, workouts, resting heart rate and HRV come in automatically, read-only. You never log anything.
A verdict every morning
One honest notification about last night. The creature wakes up glowing, fine-but-judgy, wrecked or suspicious, measured against your own 14-day baseline.
Creature Age
Every week your sleep, bedtime consistency, steps, active minutes, resting heart rate and HRV become an age, with a breakdown of which habit added the years.
Friends, minus the oversharing
Friend mode shows a mood word and a good-day count. Never your health numbers.
