Napple: Baby Sleep Tracker

Napple is a baby sleep tracker for iOS that takes the guesswork out of naps and bedtime. Instead of doing mental math on last wake time, last nap length, and how tired your baby seems, Napple learns your baby's rhythm from the sleeps you log and shows the next predicted sleep window right on the clock. Log a sleep in one tap, back-date it if you missed the start, and get a reminder when the next window opens. Lock Screen updates mean you can check timing without unlocking your phone, and family sync keeps both caregivers working from the same sleep history. Reports show trends over days and weeks. The app includes a sleep guide with typical nap schedules and wake windows by month (0–24), referencing AAP, NHS, and Sleep Foundation guidance. Built by a two-person team — an architect mom and a programmer dad — for their own son.
