A soft ankle band and app that learns what's normal for your baby, turns it into calm, plain-language insights, and checks in on how you're doing too. No alarms, no numbers to panic over. Just understanding.
Bundl quietly learns what's normal for your baby, then tells you what it means in plain words, and looks after you along the way.



The same gentle data powers two calm views: a clear picture of your baby's days, and a private space that looks after you.

No monitor can prevent SIDS, and Bundl never claims to. What protects babies is safe sleep: on their back, on a firm, flat surface, in their own crib or bassinet, with nothing else in it. Bundl supports those habits and helps keep the nursery at a comfortable temperature.
