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 calculates when to put your baby down, drawing on more than 35 studies in pediatric chronobiology. 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. THE BEDTIME ROUTINE It's the only practice whose effectiveness is solidly proven by 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. A SOOTHED BABY IN MINUTES 10 sounds chosen for their documented calming effect: white noise, pink noise, womb sounds, rain, ocean. White noise helps 80% of newborns fall asleep within 5 minutes. Built-in timer, 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 rely on scientific data by 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. ## Version history (last 5 releases) ### 1.6.4 — 2026-08-17 What's new in 1.6.4 FIX FOR AN APP THAT WOULD NOT OPEN Version 1.6.3 prevented the app from launching on some iPhones.

Fallback values follow age-based pediatric guidance (every 2.5h for a newborn, up to 4h after 6 months).

No more unlocking and reopening the app in the middle of the night to see how long baby has been asleep. HOME SCREEN WIDGET Add the Bercea widget to your home screen: it shows the ongoing sleep or feeding, or "last feeding X min ago" at a glance. A button even lets you start a nap without opening the app. ALSO The night mode shortcut is now available at any time from the home screen. Improved text contrast for better readability. Always free, no account, no ads. Your data stays on your phone. ## More apps by JULIEN DUVAL - [Lumi — Sommeil bébé](https://appshunter.io/ios/app/lumi-sommeil-bebe/id6761624678) - [StackUp Game](https://appshunter.io/ios/app/stackup-game/id6762466654) - [Lyora Sleep](https://appshunter.io/ios/app/lyora-sleep/id6766233106) All apps by JULIEN DUVAL: https://appshunter.io/developer/1890513394 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
