A sample week. Your baby's real rhythm builds from your own logs over a week or two.
Other apps tell you what a 4-month-old should do. This one watches what your baby actually does — and shows you that.
It never nags you to log. Miss a day, that's fine. The pattern appears over weeks, not hours.
Tap Sleep, set the start and end, done. Easy even one-handed with a baby asleep on you.
Safe by design

Yes. Family sharing is built in. For pediatricians, you can export a weekly or monthly summary as a PDF.

A companion who grows up with your child — from newborn to first words to first questions.
