We predict when
your baby gets sleepy.
From your baby's age and your records, Nemudoki predicts the next sleep window and tells you before it opens.
- Predictions from 4 months. Recording from day one
- No account needed. Records stay on your device
Does any of this sound familiar?
- It takes half an hour to get them down
- You don't know when to start
- Starting early only makes it worse
- You keep missing the window
- You don't know what fits your baby
It isn't that they aren't tired.
A baby who stays awake past their limit becomes overtired, and settling gets harder rather than easier. Start too early and they won't sleep either. The window that works is narrower than it seems.
We tell you before the window opens.
A notification arrives as the next window approaches, so you don't have to keep an eye on the clock. And if a day goes unrecorded, it reminds you later.
Recording is just a tap.
Tap when they fall asleep, tap when they wake. The prediction updates on its own.
It learns your baby's rhythm.
It starts from what's typical for your baby's age. As records build up, it shifts toward how long your baby actually stays awake and how long the naps run.
The pattern comes into view.
Look back at sleep by week or by month. Tap a day on the chart to pull out that day's numbers on their own.
A library of sleep sounds.
Tap once and it plays, and it keeps playing after you close the app.
Frequently asked questions
At what age can we start?
Track sleep from birth, and use sleep predictions from 4 months. Even before predictions begin, you can log sleep and wake times to look back at your baby's sleep.
What do I need to record?
Log when your baby falls asleep and when they wake up. The next sleep prediction updates using those sleep and awake periods.
How are nap and bedtime windows predicted?
Nemudoki starts with age-based guidelines. As records build up, predictions adjust to how long your baby actually stays awake and how long naps last. Predictions are estimates; use them alongside your baby's cues.
Can I use Nemudoki for free?
All features are free for the first 14 days. Sleep tracking stays free after the trial ends. To keep using sleep predictions, prediction alerts, and sleep analysis, you'll need a premium subscription. You can check prices on the in-app purchase screen.
Do I need an account, and where are records stored?
No account is needed. Your child's name, date of birth, and sleep records are stored on your device and are never sent to Nemudoki's servers. They may be included in your device backup if backups are enabled.
