Doudou: Shared Baby Tracker

Doudou is a baby log built for families where several people look after the baby. Each parent, nanny or grandparent logs on their own phone, and up to 10 phones stay in sync through a family code: no account, no email, no password.

It covers breastfeeding timers, bottles, pumping, diapers, naps and night sleep, vitamin D, and weight and height on WHO growth charts, with Home Screen widgets and a 7- or 30-day summary for the pediatrician.

Logging, family sharing, growth charts and the summary are free, with ads. An optional Premium removes ads and adds nap windows. No AI reads the log, and family data stays on a server in the EU. Made by a solo developer in France.

Available on the App Store and Google Play.
