Bercea: Baby Sleep

You put your baby down. They cry. You pick them back up, you try again 20 minutes later. They cry again. You no longer know if it's too early, too late, or if you're the one getting it wrong.

It's not you. It's the timing.

A baby put down at the right moment falls asleep in minutes, sleeps longer and wakes less during the night. The problem is that this "right moment" changes every day, and it's different for every child.

Bercea finds it for you.

🔮 NO MORE GUESSING
From day one, Bercea estimates when to put your baby down, starting from clinical benchmarks for their age. After a few naps, the algorithm learns your child's own rhythm. The predictions become more and more personal, and bedtimes more and more peaceful.

The result: you know exactly when to act. No more doubt, no more guilt.

📈 WEIGHT AND HEIGHT, ON THE WHO CURVES
Log a measurement and it lands straight onto the official WHO curves, from birth to 4 years, with the usual band from the 3rd to the 97th percentile. What counts is not the position on a given day, it is how steady the curve is.

🌙 THE BEDTIME ROUTINE
It's one of the best-supported pieces of advice in the research. Bercea includes a routine tracker: check off the steps you complete each evening (bath, story, cuddle, dimmed light…) and track your consistency over 7 days. Four steps every evening beat ten steps every other night. Bercea also measures how steady your bedtimes are across the week: the best established advice becomes a number you can follow.

🎵 A SOOTHED BABY IN MINUTES
10 soothing sounds: white noise, pink noise, womb sounds, rain, ocean. Background sound can help a newborn fall asleep, provided it stays quiet and away from the bed. Timer set to 30 minutes by default, background playback, volume alert to protect baby's ears.

📊 EVERYTHING IN ONE PLACE
Sleep, feeds, diapers, notes: track it all with one tap. The 7-day visual history shows you the trends you couldn't see before. Weekly chart, comparison with WHO norms by age, nap-by-nap detail.

🧠 AN ALGORITHM THAT ADAPTS
The first predictions start from clinical benchmarks for the age. Then the app gradually blends these values with your baby's real-life observations, up to 70% personal data after a month of tracking. Even with few logs, you get quality predictions: our simulations show that a sporadic parent reaches 80% of the accuracy of a meticulous one.

💙 WHAT ABOUT YOU?
Bercea also tracks your mood, your energy and your sleep. Because an exhausted parent who ignores it ends up breaking down. If the signals add up, Bercea points you toward the right resources. Taking care of yourself is taking care of your baby.

📚 SCIENCE MADE ACCESSIBLE
More than 30 cited studies and 22 articles in plain language, on sleep and child development. Bercea puts forward the ones that matter for your child's age today, and flags what is coming: starting solids, first teeth, separation anxiety, first steps.

👨‍👩‍👦 TWO PARENTS, NO ACCOUNT
Share tracking with your co-parent: one 6-digit code, and both phones show the same naps, feeds and routines in real time. Each of you sees what the other logged, even from a distance. Still no sign-up.

📱 ON YOUR HOME SCREEN
The widget shows the ongoing nap or feed with its running timer, or the last feed at a glance. A button even lets you start a nap without opening the app.

🔒 YOUR DATA STAYS YOURS
No account. No data collected. No server. Everything stays on your phone. Bercea works even without internet.

Free, forever. Because your baby's sleep shouldn't depend on your budget.
