Baby Duo is a newborn routine log for the two people actually living it. No forms, no menus, no waiting for anything to load. It works with no signal, and what you log shows up for your partner as soon as there's a network.
Coming soon to the App Store.

One tap and it's done: the feed, the diaper or the nap is logged. If you need to fix the time or note the millilitres, hold the button and the detail sheet opens.
Without opening the app
Shows how long since the last feed, with buttons that log without opening anything. On the Lock Screen, a ring fills toward the next expected feed.
Without a signal
Everything is saved on the phone first. Logging still costs one tap, and what you logged uploads on its own once the network is back.
Without recounting the night
There are no two histories to reconcile. It doesn't matter who logged it: the information belongs to the family and syncs on its own.
While the baby sleeps
The sleep stretch counts itself on the Lock Screen and in the Dynamic Island, so nobody has to watch the clock.
Feeds per day, average interval, hours of sleep and diaper counts. Sleep stretches that cross midnight are split across both days — which is the difference between a pretty chart and one you can show a pediatrician.
Breast or bottle feeds with a stopwatch or millilitres, diapers, sleep, bath, medication and weight. Swipe a row to fix it or delete it.
No subscription, no renewals. A newborn app gets used for 18 or 24 months, and charging a yearly fee for that looks a lot like charging twice.
Everything else, including logging from the widget, is free.
Baby Duo has no ads, no analytics and no third-party SDKs. The app has a single external dependency and none of them is an ad network. Your log lives on our own server in Germany and only people in your family can see it.
