Works with no connection
Over 170,000 defibrillators live inside the app, not on a server. On a plane, in a basement, on a trail: map, distances and guidance behave exactly the same with zero bars.
The nearest defibrillator,even where there’s no signal
Cardiac arrest doesn’t wait for a connection. SOS DAE keeps the map inside your phone: it opens in two seconds and works on a plane, in a car park, up a mountain.

The product
What SOS DAE is
Two things in one: a free emergency tool for anyone, and a paid service for organisations that own defibrillators.
Guides you while help is on the way
A call to the emergency number of the country you’re in, a 110 bpm metronome for compressions, hand placement, what to do when the AED arrives. ERC and AHA guidelines.
Corrected by whoever walks past
An empty cabinet or a locked door is reported in one tap. When several people say the same thing, the correction reaches everyone’s app.
In practice
How it works
Four steps, and none of them needs a connection.
Download the app
The defibrillator database is already inside: nothing to download and nothing to configure on first launch.
Open it and see the nearest one
Distance and direction, large, on the first screen. One tap starts walking navigation.
Follow the guidance while you wait
A call to the emergency number of the country you’re in, a metronome for compressions, what to do when the defibrillator arrives.
If you’re on site, fix the data
Confirm the AED is there, or report that the cabinet is empty. When several independent people agree, the correction reaches everyone else.
Who it’s for
Who needs it
Three different people, the same tool in their pocket.
Anyone facing a cardiac arrest
Not a responder, no training, the emergency line on speaker and shaking hands. They will use the app once in their life, and they must understand where to run in under two seconds.
Volunteers, schools, sports clubs
People who check the map calmly, to know where the AEDs in their area are, verify them on site and fix what doesn’t add up.
Companies, gyms, councils, institutions
Anyone who owns a defibrillator and has to keep it ready: pad and battery expiry, periodic checks, liability. That’s what the management service is for.
Why it matters
The problem, in three numbers
The defibrillators are out there. The trouble is that often nobody knows where, and public data is full of gaps we counted one by one.

SOS DAE Management
Do you have a defibrillator to look after?
An installed AED is not a ready AED. Pads and batteries expire, checks have to be logged, and the responsibility stays with whoever owns it. SOS DAE Management keeps it all in one place.
Thirty days’ trial, no credit card: load your devices and see straight away what’s expiring. The fee is annual and based on the number of devices; terms aren’t published yet, and we write to you before the trial ends.
Questions
Frequently asked questions
Does it really work without a connection?
Yes, and that’s why it exists. Database, search, distances and CPR guidance are inside the app: the only thing that comes over the network is the map background.
How much does it cost?
Nothing: the app is free, with no account and no ads, and it will stay that way. Only the management service for companies and institutions is paid.
Where does the data come from?
From OpenStreetMap, under the ODbL licence. It is not official data — the app says so on every card — and anyone on site can correct it: that’s how it improves.
Is it a medical device?
No. It does not replace emergency services and does not give medical advice. In an emergency the first thing to do is call your country’s emergency number.
Download it now, not when you need it
At the moment it matters, nobody has time to look for an app, wait for a download and work out how it functions.
