Sleep Gem is the baby sleep tracker that learns your baby's own wake windows and tells you when to put them down. No generic age chart: every nap you log tunes your baby's schedule, so naps get longer and nights get calmer. Built by a father of three in Singapore and refined over five years and hundreds of thousands of logged days. HOW IT WORKS 1. Log with two taps: Wake Up, Put Down, Sleep, Pick Up. 2. Sleep Gem works out your baby's wake windows from what you log and shows the next put-down time. 3. AutoOptimise keeps adjusting the nap schedule and bedtime as your baby grows, through nap transitions, sleep regressions and sick days. WHAT YOU GET • The next put-down time, always on screen, with a "Why this time?" explanation • A nap and bedtime schedule that is your baby's, not an average • Night sleep, night wakings and total sleep charts over 15 to 90 days • A plain-language morning briefing on how last night went • Mark an unwell day and the schedule adapts instead of breaking • Beginner or Advanced logging: start simple, add awake-in-crib time when you are ready • One shared log for both parents, your helper or grandparents, updated live • Edit, insert and undo entries, wit
