Nunu is the first baby sleep app that shows you the evidence behind every single recommendation it makes. In a market flooded with sleep apps offering generic advice and unverified claims, Nunu takes a radically different approach: complete scientific transparency. Every tip, every schedule adjustment, and every method recommendation comes with a confidence level — HIGH, MODERATE, or LOW — based on the quality of the underlying research. If there is no evidence for something, Nunu says so honestly. This commitment to honesty is what sets Nunu apart and gives parents the trust they need during one of the most exhausting chapters of early parenthood. The app is built on a foundation of over 500 peer-reviewed clinical studies, drawing from landmark research by the American Academy of Pediatrics (AAP 2022), Mindell (2006/2009), Gradisar (2016), Galland (2012), Hiscock & Wake (2001), Paul (2016), and nearly 500 additional published studies.
At the heart of Nunu is the Baby Sleep Wellness Index (BSWI), a composite 0-100 score that measures your baby's sleep health across six science-backed dimensions. Duration & Continuity accounts for 25% of the score, measuring how long and how uninterrupted your baby sleeps. Sleep Environment (20%) evaluates the conditions in your baby's room — temperature, darkness, noise levels, and safety. Bedtime Routine (20%) tracks the consistency and quality of your pre-sleep rituals. Feeding & Sleep (15%) examines how nutrition patterns interact with sleep cycles. Parental Wellbeing (10%) recognizes that your mental health directly affects your baby's sleep outcomes. Developmental Alignment (10%) ensures recommendations are age-appropriate and account for developmental milestones. Nunu selects from 8 evidence-based sleep methods including Responsive Settling, Positive Routines, Bedtime Fading, Graduated Extinction, and Camping Out — choosing the best approach based on your baby's age, your comfort level with crying, and what you have already tried.
Nunu is designed with the reality of exhausted parents in mind. The SOS Button provides calm, clear instructions at 3AM when you are too tired to think — complete with visual timers, emotional validation, and your own progress data, all working fully offline so you never need to worry about connectivity. The entire interface uses night mode by default, with 72pt touch targets so you can navigate even with blurry eyes, and haptic feedback only (no sounds) to avoid waking anyone. Daily logging takes under 3 minutes each morning, and the AI uses that data to adapt your plan every week. The app also includes built-in PHQ-2 screening for parental depression, recognizing that parental mental health is inseparable from a baby's sleep journey. If screening suggests further evaluation, Nunu provides appropriate guidance and resources.
Additional features include AI-powered room safety analysis that helps you identify potential hazards in your nursery, a PDF export function so you can share your baby's sleep data and progress with your pediatrician, corrected age calculations for premature babies to ensure developmentally appropriate recommendations, and weekly detailed progress reports that show exactly how your baby's sleep is improving across all six BSWI dimensions. Nunu generates a personalized 4-week progressive plan that evolves with your baby — not a static one-size-fits-all schedule, but a living plan that responds to real data. For parents who want to make informed decisions about their baby's sleep based on actual science rather than anecdotal advice, Nunu provides the evidence, the tools, and the support to make it happen.
