One sentence

Darli is a baby tracker for iPhone that logs sleep, feeds and diapers in a single tap and predicts the next sleep window from the baby’s own rhythm.

Short · about 50 words

Darli is a baby tracker for iPhone. Sleep, nursing, bottles, diapers and pumping each take one tap – from the Lock Screen and through Siri, too. From the rhythm logged so far, the app estimates when the next sleep window opens. Two parents can connect their iPhones and see the same picture.

Darli is a baby tracker for iPhone, built by independent developer Tibor Stefán in Munich. Sleep, nursing, bottles, diapers and pumping are logged with a single tap – straight from the Lock Screen, the Dynamic Island or through Siri, designed for one hand, a baby in the other arm and a dark room. A day ring shows the whole day on one clock. From what has been logged so far, Darli estimates when the next sleep window opens; that calculation runs on the device. Two parents connect their iPhones with a QR code and see the same picture. Darli is available in six languages and needs no account.

What the app does

Described plainly, without marketing. All of it ships in the current version.

Day ring

Sleep, feeding, diapers and pumping sit as rings on one clock. A single glance shows how the day has gone.

One tap is enough

An entry takes one tap. The time can be nudged backwards afterwards, for when you remember later.

Lock Screen and Siri

Sleep and nursing timers run as a Live Activity in the Dynamic Island and on the Lock Screen. Siri handles the common entries.

Wake window forecast

Darli learns the baby’s age and rhythm and estimates when the next sleep window opens. For the first few days it says plainly: “Darli is still learning.”

Night mode

In the evening the interface turns dark on its own, so nobody is dazzled at three in the morning.

Nursing and bottles

Nursing with side and timer, bottles with amount and milk type. Solids can be switched on.

Family & devices

A second iPhone joins by QR code. From then on both parents see the same picture – with no account.

Several children

Siblings can be added and switched at the top.

Sleep sounds

24 sounds with a timer, and switchable off. Noise, nature, music box.

Reminders

Vitamin D, medication, exercises – as their own ring with repetition, off by default.

Where Darli stops

These limits are part of the story. We would ask you to write them down with it.

Forecast and AI

We say openly where AI is involved and where it is not – not least because it is a fair question to ask of a product for parents.

The forecast runs on the device

The wake window is calculated locally on the iPhone, using a formula. No language model and no cloud AI service is involved. The baby’s entries go nowhere for it.

Images, copy and video are made with AI

Illustrations, website copy and video on darli.app and in the App Store artwork were produced with AI assistance. The people shown are not real.

The support chat is an AI assistant

On support.darli.app a language model answers from the help page. It is labelled as an AI assistant and refers medical questions to a doctor or midwife.

The full account

darli.app/en/ai-transparency goes through each point in turn.

Angles that work

Suggestions, not requirements – and honestly ordered by where Darli actually has something to add.

The invisible list in your head

New parents carry sleep times, feeds and diapers around as a mental list. The interesting question is not whether an app can store that, but which part of the load technology genuinely takes away – and which part it does not.

At 3 a.m. nobody needs a form

Built for one hand, a baby in the other arm and a dark room. A design angle: the Lock Screen instead of opening an app, large targets instead of fields, night mode on its own.

Making care work visible

When both parents see the same picture, who ‘owns’ the overview shifts. That is a conversation about default parents and the division of labour, not about a feature.

Prediction without an AI cloud

The wake window forecast runs locally, on a formula rather than a language model. A reason to ask when AI is actually needed – particularly for sensitive data about a child.

Less screen time through better software

Tracking sounds like more phone. The counter-argument: if an entry takes a second and works from the Lock Screen, software shortens the time on the device instead of extending it.

One developer, six languages

Darli is built by one person, in Munich, without investors, and ships in six languages. How that works – and where it runs into limits – is the founder story behind it.

Logo and app icon

App screenshots

Real captures from the app, without marketing text. The babies are called Mila and Ivy in the demo data; none of this is real user data.

App Store artwork

The artwork from the App Store, with text and photography. The people shown are AI-generated and not real.

App preview video

Usage. Logo, screenshots, App Store artwork and video may be used for editorial coverage of Darli, unaltered and credited to “Darli”. Not permitted: altering the logo, using it as your own brand or product mark, and any use implying a partnership or endorsement that does not exist. For anything beyond that, a short email is enough.

Numbers

Darli has been on the App Store since 27 July 2026. We will publish usage figures once they mean something – a few weeks after launch, any number is mostly a snapshot. If you need concrete figures for a piece, ask us: we will either give you a number we can stand behind, or tell you honestly that we do not have it yet.
