Bercea: Baby Sleep
Predicted naps, calm nights
Free · Designed for iPad. Not verified for macOS.
Bercea learns your baby's rhythm and tells you when to put them down. Bedtime routine, soothing sounds, parent tracking. Free, no account, no ads.
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 World Health Organization curves, from birth to 4 years, with the usual band from the 3rd to the 97th percentile. What tells you most is not the position on a given day, it is how steady the curve is: a child who follows their own curve is doing fine, even far from the average.
21 ARTICLES, RANKED BY YOUR CHILD'S AGE
Sleep and child development, with sources. Bercea puts forward what matters for your child today and flags what is coming: starting solids, first teeth, separation anxiety, first steps. You read the right thing at the right time, not an encyclopedia to sift through.
THE BEDTIME ROUTINE
It's one of the best-supported pieces of advice in the research. 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 bedtime is across the week, its median and its spread: 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.
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.
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. The timer also appears on the lock screen and in the Dynamic Island, 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.
What's new in 1.8.0
A PERSONAL SLEEP CHECK-UP
Broken nights? Answer the questions a sleep consultant would ask at a first appointment, and Bercea suggests a plan that fits your child: what to check with your doctor first, the likely causes of the wakings, what can change from tonight, and a method that respects where you stand on crying. Every piece of advice is based on studies checked one by one. Your answers stay on your phone.
LOG A WAKING IN ONE TAP
In night mode, the Waking button logs a night waking with no questions asked. Bercea finally sees broken nights, and suggests the check-up when they keep happening.
Still free, no account, no ads.
