Sleep Gem is a baby sleep tracker that learns your baby's own wake windows and tells you when to put them down. Log a nap in two taps and get a baby sleep schedule that is yours, not an average from an age chart.

WAKE WINDOWS THAT LEARN
Every baby has wake windows they can handle before the next sleep, and they change as your baby grows. Sleep Gem works them out from what you log and keeps adjusting the nap schedule and bedtime through nap transitions, sleep regressions and unwell days. The next put-down time is always on screen, with a "Why this time?" explanation.

A BABY SLEEP SCHEDULE FOR EVERY AGE
Newborn sleep schedule, 4 month old sleep schedule with three naps, or a toddler nap schedule with one: Sleep Gem starts from age-appropriate wake windows on day one and personalises them within a week.

WHAT YOU GET
• Two-tap sleep log: Wake Up, Put Down, Sleep, Pick Up
• Next put-down time and bedtime, updated after every entry
• 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-cot time when you are ready
• One shared baby sleep log for both parents, your helper or grandparents, live
• Edit, insert and undo entries, with a roller time picker for exact times
• Dark mode for 3 a.m. night wakings
• Care log (feeds, nappies) and WHO growth charts
• English, 中文 and Bahasa Indonesia

WHO IT IS FOR
Parents of newborns, infants and toddlers up to about three years, especially first-time parents guessing when the next nap should be, families working through the 4-month sleep regression or a 2-to-1 nap transition, and anyone sharing care with a partner, helper, nanny, infant care or grandparents.
