Free for a week

A baby monitor that actually calls you.

Jon Blund listens by the crib and rings your phone the moment your baby cries. Not a notification you might sleep through — a real call, on the mobile network.

No app to install. No hardware to buy. Two phones and coverage.

Why it works anywhere

Thick walls beat most baby monitors. They do not beat a phone call.

Ordinary monitors talk over their own little radio link. Brick, concrete, old plaster and a floor in between all eat that signal — which is why so many of them crackle, cut out, or go silent in exactly the room you needed them in.

The usual way no signal

Range you have to hope for

Two units and a radio link between them. Every wall, floor and steel beam takes a bite out of it, and the further you walk the less you can trust it.

Jon Blund ringing

Range you already pay for

The call goes over the mobile network, the same one that reaches you in the basement, the garden or three floors up. If your phone has coverage, Jon Blund reaches you.

How it works

Three steps, then you can sleep.

Nothing to unbox, nothing to pair, nothing to charge but the phone you already own.

01

Put a phone by the crib

Open the page, allow the microphone, and set the phone down beside your baby. Screen on, plugged in. That is the whole setup.

02

It listens for crying

Not the fan, not the traffic outside, not a door closing downstairs. It waits for a sound that keeps going long enough to be a real cry.

03

Your phone rings

A real call, so it cuts through silent mode. Answer and you hear the room. Hang up, and Jon Blund goes straight back to listening.

What you get

Everything a monitor does, minus the monitor.

Nothing to buy

No second device to order, unbox, pair and eventually lose the charger for. You already own both halves.

No app, no account wall

It is a web page. Open it, allow the microphone, and it works. Nothing to install on either phone.

It rings, it does not ping

A notification is easy to sleep through and easy to silence. A phone call is neither, which is the entire point.

Walls are not the limit

Downstairs, in the garden, at the neighbour's for coffee. Coverage is the only range you have to think about.

Back to listening in seconds

Hang up and it waits twenty seconds — long enough to reach the crib — then starts listening again on its own.

You control the ceiling

Spending stops at a limit you can see. Jon Blund pauses rather than quietly running up a bill you did not agree to.

Pricing

Pay for the nights you actually use it.

A small monthly fee and a little per call. A quiet month costs less than a coffee, and a rough one is capped.

Before you start

What Jon Blund needs, and what it is not.

Better you read this here than find it out at three in the morning.

Two phones with coverage

One stays by the crib and listens. The other stays with you and rings. Both need a mobile signal — that is the whole hardware list.

The listening phone stays awake

Browsers stop the microphone when a screen locks, so that phone keeps its screen on and stays plugged in. Jon Blund dims itself so it is not a lamp beside the cot.

Save the number it calls from

Jon Blund sends you a contact card to pass on. Saved in the other phone, the call gets through even when everything else is silenced.

It is not a medical device

Jon Blund listens for crying. It does not monitor breathing, movement or anything else, and it never replaces someone checking on the baby.

Try it tonight. It is free for a week.

Open it on the phone that will sit by the crib. Two minutes and it is listening.

No card for the first week. No app. No hardware.
