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, with a roller time picker for exact times • Dark mode for 3 a.m. • Care log (feeds, diapers) and WHO growth charts • English, 中文 and Bahasa Indonesia WHO IT IS FOR Newborns, infants and toddlers up to about three years. Especially useful if you are: • A first-time parent guessing when the next nap should be • Working through the 4-month sleep regression or a 2-to-1 nap transition • Sharing care with a partner, helper, nanny, daycare or grandparents • Planning to sleep train and want a solid routine first FREE Sleep Gem is free. No subscription, no paywall, every feature included. Start as a guest, no account needed. WHAT PARENTS SAY "Lifesaver for parents who manually calculate and record wake times.

I will continue to improve the app to allow babies and parents to get the best sleep possible ### 5/5 — Baby sleep = rocket science but this app helps so much! *2023-01-30* Prior to this, every time my baby woke it was intense mental arithmetic and remembering how to correct for each nap or sleep fragment. This app now does it for me and as a FTM I couldn’t be more grateful. Thanks so much to the developer for investing the time in doing this and for regular updates and improvements. It is truly appreciated! **Developer response:** Thank you so much for your kind encouragements. I’m very happy to be able to help, and I hope to continue improving the app to help more parents get better sleep. 😃 ## Frequently asked questions about Sleep Gem ### How does Sleep Gem help improve my baby's sleep?
