One button: «I'm OK»
Press it and the whole family gets the message with your location. No need to unlock your phone.

The power went out. Then the signal.
On 28 April 2025, a blackout hit almost all of Spain and Portugal. For hours, millions of people couldn't reach their loved ones. We're building pocket devices that let you send each other «I'm OK» and where you are, even with no power and no signal. And with no fees.
- 12:40
You message your family.
«Is everyone OK?». And the message just keeps spinning.
- 13:15
Nobody answers.
With no network, messages, calls and texts sit in a queue. You don't know if they get through.
- 15:45
Three hours without a word.
The worst part of a blackout isn't the dark. It's not knowing if your people are OK.
- With Montered
«I'm OK» gets through anyway.
Device to device, by radio, without going through any mast. And only your family sees it.
How it would work at home
One device per person. A network that's yours alone.
Short messages
You type them on your phone like any chat app. They get through even with no network, no wifi and no power.
Where everyone is
Everyone's position on a downloaded map. And an SOS button that keeps repeating until someone confirms it.
The kit
Three devices. One per person.
They come paired from the factory, so they only talk to each other. They charge with the same charger and fit in a pocket.

An emergency device shouldn't charge you every month for sitting in a drawer. You pay once and it's ready the day the power goes out. No fees, ever.

✕
It's not a walkie-talkie
There's no voice: just short messages and your location. In exchange, it reaches further on very little battery.
✕
It doesn't replace 112
In an emergency, call 112 (the European emergency number) or your local one if you can. This is for knowing your family is OK.
✕
It doesn't work miracles in the city
Among buildings, range drops to a few hundred metres or a few kilometres. A repeater on the roof extends it.
Family pack · in development
You'll hear before anyone else.
It's not on sale yet. If you're interested, join the waitlist: it helps us decide when to launch it and what it should be like.
Do I need a licence?
Not in Europe. It uses a licence-free radio frequency, the same one many household devices use, and stays within its limits. Outside Europe the rules are different, so we can't promise it yet.
How much will it cost?
We're still working it out. The idea is a pack of 3 devices for ≈ €250 or less: an approximate price, not on sale yet. No fees, ever. Tell us on the waitlist what you'd pay.
When will it be out?
After the hunting line, which is the one we're testing now. People on the waitlist will be the first to try it.
