Baby sleep tracker: one tap, and the day makes sense

You don't need to know why your baby sleeps the way she does. You just want to know when the next quiet hour is coming. That's exactly what Darli is built for: one tap is all it takes, the prediction sorts the rest.

Why log anything at all?

Tracking sleep is not about control

Nobody needs a log to know the night was short. The real reason to track your baby's sleep is a different one: only once Darli knows when your baby fell asleep and woke up can the prediction start working for you. A few entries become a pattern, and the pattern becomes a look ahead.

That's why logging is radically simple: one tap when your baby falls asleep, one tap when she wakes up, that's it. No categories, no notes, no form to fill in. One-handed, at night, half asleep, with the baby on your arm.

And if you miss a nap? It happens. Darli is a baby sleep tracker app that backs your instincts instead of replacing them. You stay the expert on your child; Darli just remembers the times so you don't have to.

Night mode

In the evening, Darli goes dark on its own.

When the day winds down, Darli switches to night mode by itself: dark background, big elements, nothing glares. The one tap you need sits exactly where your thumb expects it.

Nobody needs a form at 3 am. You tap once, put the phone down, and your head is back with your baby instead of inside an app.

When you know how long it will last, the hour is yours.

A nap only counts as rest for you if you can trust it. Darli shows you how long your baby usually sleeps around this time, and you decide what to do with the hour.

How Darli helps

A prediction that earns your trust.

Darli learns your baby's age and rhythm right on your device and predicts when the next sleep and the next feed are coming. The day ring shows the whole day at a glance: what happened, what's happening now, and what's next.

And to be honest: no baby sticks to a forecast, ours included. The prediction is guidance, not a promise. But it's guidance that gets a little better every day, because it learns from your baby instead of from an average one.

Frequently asked

Why should I track my baby's sleep at all?

Not to prove anything, but so the prediction can do its job. From your entries, Darli learns your baby's rhythm and shows you when the next sleep is likely coming. You plan your day around real patterns instead of guesses.

How does the sleep prediction in Darli work?

Darli combines your baby's age with the rhythm it learns from your entries, right on your device. That becomes a forecast for the next sleep and the next feed, visible on the day ring. It's guidance, not a promise, and it gets more accurate with every day.

What happens if I forget to log a sleep?

Nothing bad. The prediction works with patterns across several days, so one missing entry won't throw it off. You can add times later or simply let it go. Darli is meant to take weight off you, not hand you a new chore.

Can I log at night without fully waking up?

Yes, that's exactly what night mode is for. In the evening, Darli goes dark on its own, the elements get big, and nothing glares. One tap of your thumb is enough, even one-handed with the baby on your arm.

I don't want to monitor my baby around the clock. Isn't a sleep tracker app the wrong idea?

That gut feeling is right, and Darli is deliberately built differently. No scores, no grades, no comparing your baby to others. Darli remembers two times a day so your head can let them go. It backs your instincts, it doesn't replace them.
