About Tottli

A small studio building calm tools for new parents.

Tottli is a baby-tracking app for iPhone and Apple Watch. It logs feedings, diapers, sleep, and pumping sessions in a single tap, so the people caring for a newborn spend less time fiddling with an app and more time with the baby. Tottli is made by Westerby Labs LLC, an independent software studio based in Owatonna, Minnesota.

Why we build it this way

The first months with a baby are exhausting, and most logging happens one-handed, in the dark, at 3 AM. So Tottli is designed to be fast, quiet, and forgiving: one-tap logging with smart defaults, a true-black dark mode, offline support, and a shared timeline so partners, grandparents, and nannies all see the same picture. We don't run ads, and we don't sell your data.

About the Tottli blog

We also publish a blog on newborn sleep, feeding, pumping, diapers, and the realities of the first year. Our aim is practical and calm: clear answers to the questions parents actually ask, without fearmongering or filler. Articles are written and edited by the Tottli team. When we give a specific number or threshold, we link to where it comes from, usually the American Academy of Pediatrics (AAP), the CDC, or the World Health Organization (WHO).

This is not medical advice

Tottli is not a medical provider, medical device, or emergency service, and nothing in our app or on our blog is medical advice. Every baby is different. Always consult your pediatrician or another qualified healthcare professional for guidance specific to your child, and contact local emergency services in an emergency. See our Disclaimer for more.
