A survival kit that works with no signal.
Disaster Mode saves your local emergency number, the nearest hospitals, official alerts and an I’m-safe text to your phone while you still have signal. When the bars go, it all still works.

Red tropical cyclone warning · 38 km · GDACS
Six things, in the order a frightened person needs them.
Call first
Your local emergency number, from a checked table for each country. 112 when the country is not known. It dials from the kit with no data.
Alerts near you
Earthquakes, cyclones, floods, volcanoes, wildfires and US warnings, with how far away they are and a link to the official update.
Nearest help
Hospitals, clinics, pharmacies, police and fire stations within 25 km, nearest first, each with a call button and directions.
Text I’m safe
Pick the people who should hear from you first. One tap writes the message, with where you are if you want, in your phone’s own texts.
Your emergency card
Blood type, allergies, medication and notes for whoever helps you. It stays on your phone. NUM never receives it.
Go bag
A short checklist of what to grab, ticked off on the phone and still there when the network is not.
Save it once. Use it with zero bars.
Nothing reaches a phone with no signal, so the kit has to be on the phone before the signal goes.
- Turn it on with signalOpen Disaster Mode and allow your location. NUM builds your kit for where you are and saves it on this phone.
- Lose the networkEverything in the kit runs on the phone itself: numbers dial, texts go over the cell network or satellite texting where your phone has it, directions open your maps app.
- Update when you canWhen a connection comes back, one tap refreshes the alerts and the nearest help. If a feed can’t be reached, the kit tells you.
Official sources, checked every few minutes.
GDACS
The UN and European Commission’s disaster alert system: earthquakes, cyclones, floods, volcanoes and wildfires worldwide, each with a green, orange or red impact level.
USGS
Earthquakes of magnitude 4.5 and up anywhere in the world, with tsunami flags.
US National Weather Service
Watches and warnings for your exact location in the US: hurricanes, tornadoes, flash floods, fire, evacuation and shelter-in-place orders.
Orange and red events, earthquakes of magnitude 6 or more, tsunami flags and serious US warnings within range raise an alert. Smaller activity nearby is shown, but never switches anything on.
NUM is not an emergency service. In an emergency, call your local emergency number first. Every kit leads with it. NUM doesn’t list shelters, because they open and close by the hour in a disaster; the kit links the official source instead.
The short answers.
Is Disaster Mode free?
Yes. Anybody gets the kit and the alerts, with or without a NUM account. It is part of the NUM app at app.itsnum.com, with nothing to buy.
Does it really work with no internet?
Once the kit is saved, yes. NUM saves it to your phone while you have a connection, and everything in it then works with zero bars: emergency numbers dial, the I’m-safe message goes out through your phone’s own texts, and directions open your maps app. It needs a connection once, to save the kit in the first place.
Is NUM an emergency service?
No. Every kit leads with your local emergency number from a checked table, and 112 when the country is not known. In an emergency, call that number first.
Where do the alerts come from?
GDACS (the UN and European Commission’s disaster alert system) for earthquakes, cyclones, floods, volcanoes and wildfires worldwide; the USGS for earthquakes of magnitude 4.5 and up; and the US National Weather Service for warnings at your exact location in the US. If a feed cannot be reached, the kit says so rather than showing an empty list as all-clear.
When does Disaster Mode turn on by itself?
It flags an alert near you for an orange or red GDACS event, an earthquake of magnitude 6 or more or any tsunami flag within range, or a serious US warning such as a hurricane, tornado, flash flood or evacuation order. Smaller nearby activity is shown, but never switches anything on.
Does NUM know which shelters are open?
No, and it will not guess. Shelters open and close by the hour in a disaster, so the kit links to the official source for shelters and alerts instead.
What happens to my emergency card and contacts?
They stay on your phone. NUM never receives your blood type, allergies, medication or family numbers. The location used to build the kit is rounded to about a kilometre and stored against nobody.
Save your kit before you need it.
It takes a minute with signal, and it’s free for anyone, anywhere NUM can see.
