Wake window prediction
An age-calibrated algorithm calculates exactly how long your baby can comfortably stay awake, adjusting in real time based on today's actual sleep history.

Features
Everything you need at 3 AM
Built for sleep-deprived parents. Every feature is designed to be glanceable, actionable, and calm.
Overtiredness risk indicator
A live low / medium / high indicator tells you how close your baby is to the overtiredness threshold — so you act before the meltdown, not after.
Sleep sounds
Built-in white noise and pink noise with adjustable volume and auto-stop timer. No subscriptions, no ads — just the sound that settles your baby.
Daily AI sleep digest
Every morning, a plain-language summary of yesterday's sleep — what went well, what to watch, and a concrete recommendation for today's nap schedule.
Smart nap reminders
A quiet push notification 15 minutes before the predicted nap window opens. Gentle enough not to startle a sleeping baby, timely enough to actually help.
Available in 6 languages
Fully translated into Ukrainian, English, French, German, Italian, and Spanish — with more on the way. Because parenting doesn't have a language barrier.
How it works
Up and running in under a minute
No lengthy setup. No questionnaires. Just tell the app about your baby and start tracking.
Create your baby's profile
Enter your baby's name, date of birth, and estimated due date if born early. Corrected age is calculated automatically for premature babies.
Tap Start Sleep
One tap to begin, one to end. Every session is recorded automatically — wake time, sleep duration, and time to settle.
Get smarter every day
The app learns your baby's actual rhythm over time. Predictions improve with every session logged — no manual adjustments needed.
Your data stays yours. Baby Rhythm stores all sleep data securely within your account and on your device. We do not sell your information, share it with advertisers, or use it for any purpose beyond making the app work for you. No ads. No tracking. No surprises.
