About Nemudoki - Baby Sleep Timing
Thirty minutes. An hour. Still not asleep.
The reason may be when you start. A baby who stays awake too long becomes overtired and fights sleep even harder — and starting too early doesn't work either.
Nemudoki uses your baby's age and your own records to show when the next sleep window is likely to open. Recording takes one tap: asleep, or awake. Open the app and today's sleep is already there.
● One tap to record
Tap "asleep" and "awake." That's all. There are no forms to fill in. The home screen shows today's sleep and what's predicted next.
● Know before it's too late
A notification arrives before naps and bedtime. If you've forgotten to record something, Nemudoki lets you know quietly.
● It follows your baby's rhythm
It starts from what's typical for your baby's age, then adjusts as your records build up.
● Look back
See how total sleep, wake times, and bedtimes have shifted, week by week or month by month. You can go back through past periods to trace how the rhythm has changed.
● Sounds for settling
Rain, waves, a campfire, a heartbeat, womb sounds, and many more.
● Your records stay on your device
No account is required. Your child's sleep records never leave your phone.
● Who it's for
Children from newborn to around three years old. Predictions don't appear before four months, since sleep rhythms haven't settled yet — recording and the sleep history are still available.
● Premium
All features are free for 14 days from install, with no purchase required.
Monthly and yearly subscriptions are available; prices are shown in the app.
Recording, sleep history, multiple children, and reminders for missed records remain free after the trial. Premium adds the next sleep prediction, prediction-based notifications, the summary screen, and every settling sound.
Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel anytime in your App Store settings.
Nemudoki is not a medical device. Times shown are estimates. Talk to a doctor about your child's health.
