Authors discuss the routine changing and favorite sounds disappearing. Editing the diary by hand and quick access to a saved backdrop both help.

Rank 21. Review score: 62 out of 100. App Store rating: 4.9★ · 4,083 ratings
62of 100
A baby sleep tracker with an algorithm that predicts wake windows. Predictions work well for typical schedules, but the algorithm is slow to adapt when a baby transitions to a new developmental phase.
Praised: Accurately predicts the next sleep time and nap duration, which helps plan the day.
Complaints: The algorithm adapts slowly when a baby transitions to a new number of naps and gives outdated recommendations for weeks.
Best for: New parents who want to build a baby's sleep schedule from data rather than intuition.

One of the few apps with genuine long-term loyalty: families have used it for over a decade for children and adults alike. Stable all-night playback without crashes and reliable audio quality are its core value.
Praised: Fan sound and classic white noises play without interruption all night at any volume.
Complaints: A recent update removed some sounds and broke familiar navigation, frustrating longtime users.
Best for: Parents with infants and adults who need a simple, reliable white noise player
Rank 22. Review score: 62 out of 100. App Store rating: 4.8★ · 2,204 ratings

A proven choice for newborns and infants: multiple generations of parents confirm the effectiveness of white noise. Product weaknesses include no gradual fade-out timer and sound that sometimes stops every 30 minutes without the paid version.
Praised: White noise and the mountain river sound reliably calm newborns and help them stay asleep.
Complaints: Without the paid version, playback stops rather than looping indefinitely.
Rank 6. Review score: 70 out of 100. App Store rating: 4.8★ · 13,534 ratings

One of the richest selections of machine-style sounds: over 100 options with the ability to create custom mixes, plays in the background with no noticeable battery drain. The main downside is the shift to a subscription model for longtime users.
Praised: Custom mixes of multiple sounds are saved and launched with a single tap.
Complaints: One popular preset contains a repeating stray click that becomes noticeable during extended listening.
Best for: Parents with young children and anyone who wants to fine-tune background noise to their liking

Smart Sleep Coach by Pampers addresses the narrow task of training a baby's sleep schedule: the algorithm predicts a sleep window and adjusts the routine based on real sleep data. The app works for its audience, though advice is not personalized to each baby's individual rhythm.
Praised: The sleep window predictor genuinely works and helps parents catch the right moment before overstimulation.
Complaints: After four to five months the schedule stops adapting to the baby's individual rhythm and delivers generic recommendations.
Best for: Parents of newborns building their first sleep routine
