Napper: Baby Sleep Tracker

What it does

Napper is an AI-powered sleep tracker and scheduler designed for parents of newborns and toddlers. The app's core function is to learn a baby's unique sleep patterns by tracking activities like naps, feedings, and diaper changes. Based on this data, it generates and continually updates a personalized daily schedule, predicting optimal times for sleep to help avoid an overtired baby and create a more predictable routine for the family.

Where it shines

Napper stands out by combining a friendly, approachable interface with a data-driven core. The onboarding is a great example, using a mascot and an animated "plan building" sequence (02:00) to make data collection feel engaging and purposeful. The main dashboard (04:42) is another highlight, presenting the day's schedule as a clean, 24-hour clock face. This visual representation makes it easy to see upcoming naps and bedtime at a glance. Finally, the app’s educational component, an integrated multi-day course on baby sleep (09:31), elevates it from a simple utility to a comprehensive parenting resource.

UX highlights

Visual Schedule: The circular 24-hour clock on the dashboard (04:42) is an intuitive way to visualize the entire day's sleep and wake windows.
Smart Error Handling: The "Activity Collision" modal (04:56) is a thoughtful way to manage conflicting user inputs without causing frustration.
Expectation Management: A persistent "Napper is learning" message on the dashboard manages user expectations about the initial accuracy of the AI predictions.
Comprehensive Tracking: The app allows for detailed logging of not just sleep, but also various types of feeding, diaper changes, temperature, and medicine (06:58).
Rich Sound Library: An extensive library of noises, lullabies, and soundscapes (05:35) provides added value and a tool to help soothe the baby to sleep.
Data Visualization: The "Trends and Statistics" section (10:22) offers clear graphs to help parents identify patterns in their baby's activities over time.

Monetization & growth

Napper uses a soft paywall with a free trial model. During onboarding, after collecting user data and demonstrating value through educational content, it presents a screen explaining the 7-day free trial (03:27). The subsequent paywall (03:31) offers three subscription tiers (Yearly, Quarterly, Monthly), with the yearly plan heavily discounted and highlighted as the primary option. The app requires users to sign up and start a trial to access the core features, making it a premium product from the outset.

Who it’s for

This app is clearly designed for new parents, particularly those with infants and toddlers who are struggling to establish a consistent sleep routine. It appeals to parents who are data-curious and want a structured, science-backed approach to their baby's sleep. The educational content and supportive tone also make it suitable for first-time parents who may feel overwhelmed and are looking for guidance and reassurance.

Notes & opportunities

The onboarding flow is quite long and requires a subscription before the user can see the main interface. While the app does a good job of building value beforehand, this could be a point of friction for some users. Introducing a limited-access free version might capture a wider audience. Additionally, while the statistics section is useful, adding more direct insights or callouts on the graphs (e.g., "Nicole's naps are getting longer!") could make the data even more actionable for tired parents.
