I need help

One platform

Three jobs, one app.

Get everyone out. Help each other while you wait. Prove exactly what happened — for every building, free.

Evacuation

Get everyone out.

Evacuate, lock down, and watch everyone reach safety — a live count while it still matters, not a clipboard afterwards.

See the count Help nearby

Help each other.

A puffer, an EpiPen, eyes on a missing child — reach the people already around you. No register, and nobody is tracked.

How help nearby works Evidence

Then prove it.

A sealed, signed record of exactly what happened — that a lawyer, a regulator, or the person in the footage can verify in seconds, offline, without asking us.

Duress Evidence

Evidence shouldn't ask for trust.
It should survive without it.

The same platform runs court-grade management for incident recordings. Every byte checked on the way in, a chain of custody that can only grow — and a verdict a lawyer, a regulator, or the person in the footage can check for themselves, offline, without asking us.

See Duress Evidence Verify a bundle — no account

Checked at the door.

Every segment hashed, the Merkle root reproduced, the manifest signed — the cryptographic gates run before a recording is accepted, never after.

A record that only grows.

Append-only, hash-chained, with signed checkpoints anchored in a public transparency log. Change one entry years later and every link after it breaks, visibly.

You don't have to trust us — and here's why that's real.

Drag a disclosure bundle onto a page and it verifies in your own browser, offline, with nothing installed. Honest about its limits: independent witness cosigning isn't established yet, so the best verdict is Structure verified (unwitnessed v1) — never a plain "verified". Why "trust us less" holds up →

Accountability

The end of “we think everyone got out.”

Two counts run at once — people answering for themselves, wardens answering for spaces — because a shopper, a Year 2 class and a patient under anaesthetic cannot tap a button.

D block reported clear — but two people there still haven't answered. Check again.

The disagreement. A cleared area with an unanswered person inside is the most valuable alert of the day. For hospitals →

9 answered from off site. Told, answered, and counted apart — nobody searches a building for someone who was never in it.

The honest denominator. Who is actually here today — not a stale list of everyone who could be.

Help around you

The person you need is usually already there.

One in nine Australians has asthma. Someone at the park probably carries a reliever, someone at the beach knows CPR — EVAC is how you reach them without a register, a list, or anyone being tracked.

Can help · 400 m

Ask, properly. People nearby who said yes to being asked. Nobody appears until they choose to come. How it works →

Asked for: an adrenaline autoinjector and someone current in CPR — because a collapsed person usually needs both at once.

Ask for more than one thing. The scan runs once; helpers answer for what they can do.

Keep an eye out: red jumper, about eight, near the playground ten minutes ago.

Eyes out for a missing person. The description, never the name — and a sighting goes straight to whoever is searching.

Any building

Schools, offices, clinics, venues, warehouses — set up in five minutes, free for one site.

The catch

Free. Actually free.
Here's how.

Buildings pay for the paperwork — signed reports, drills that run themselves, the connections IT asks for. That pays for everything else. You are not the product. The paperwork is.

Never tracked.

We never know where you are. Following a place says what you care about — never where you're standing.

Never sold.

Not to advertisers, not to brokers, not to anyone. Written into the terms.

Never spammed.

Emergencies, and the drills you asked about. That's it — or we've failed.

Never trapped.

Unfollow in one tap. Delete your account and everything goes with it. Reply STOP and texts stop.

Registering stores exactly two things.

minute one

Find your building. Type the address. Confirm it's yours. Say who's responsible for safety.

Minutes two and three: where people go. Drop the points on the map — or place them standing in the building, where they get placed right.

Minutes four and five: everyone in. One link, or one QR held up in a staff meeting. Done — schedule your first drill.

Not verified yet: alerts reach only the people you invited. Verification unlocks everyone present, and everyone following.

Strangers only after we've checked. Nobody can register your school and alert a suburb.

How the count actually works.

Two counts run at once. People answer for themselves — one tap, from the lock screen, silent in a lockdown. Wardens answer for spaces — each area swept and reported clear, because a shopper, a Year 2 class or a patient under anaesthetic can't tap anything.

The denominator is honest too: it's who is actually in the building today — visitors signed in, staff who stayed home left out — not a stale list of everyone who could be.

And someone nobody could reach is counted apart from someone who didn't answer. They didn't decline — nobody asked them. That difference decides whether anyone goes back inside.

Run the demo drill →

The ending is the hard part.

In Hawaii in 2018, a false missile alert was cancelled internally within minutes — and took 38 minutes to reach the public. The alert is easy. The ending is where systems fail.

So EVAC treats the all-clear like the alert: it goes to everyone who was told — including people who already said they were safe — and it keeps trying after the event closes, because an all-clear that hasn't landed grows more urgent, not less.

Someone who never hears the ending stays hidden, and stays counted as missing. That's why it's held to the same bar.

What a family hears →

When the two counts disagree.

A warden reports D block clear. Two people who were in D block still haven't answered. Both statements are honestly made — and they can't both be the whole story.

Most systems would average that away. EVAC raises it as its own alert, because a cleared area with an unanswered person is exactly where somebody gets left behind — and the moment to check again is now, not in the report afterwards.

Reunification, without the car park chaos.

Every inquiry into a school emergency finds the same failure: nobody knew where the children were, or who was allowed to take them. Two guardians drive; a child is released to whoever arrives first.

So the plan is made on a calm afternoon: where to collect, who collects, a named backup, photo ID. On the day, every guardian sees the same instruction — and nobody is released to somebody the school wasn't told about.

What a guardian sees is status a teacher confirmed and the place to go. Never a child's location. The school controls the link, because the school holds the enrolment record and any court orders.

For families →

How you ask strangers without a register.

There is no map of who carries what — a standing register of people's medication would be a medical record, and we refuse to build one. So the ask works the other way around.

It goes out wide, to people who said yes to being asked. Each phone decides for itself whether it's close enough. Nobody answers, nobody is seen. Somebody taps "I can help" — only then do they appear, only to you, and you talk without either of you sharing a number.

What people say about themselves — "I know CPR", "I'm a nurse" — is shown as exactly that: what they said. And the first instruction, always: call 000 first.

How the ask works →

The first minutes, used properly.

Call the police immediately — the "wait 24 hours" rule is a myth, and for a missing child or a person with dementia the first hours matter most. EVAC's job is what happens around that call.

Inside a venue: a person on every exit — a checked exit is worth nothing, a staffed one is a fact — and a sweep, area by area, with sightings logged as sightings. Outside: phones nearby get the description, never the name, and a possible sighting goes straight to whoever is searching.

Most people are found close by, on foot, by somebody who happened to look up. The system just multiplies the number of people looking up.

Why silence and touch are features.

In a lockdown, a phone that chimes can give away where someone is hiding. So a lockdown alert makes no sound and no light — and answering it is just as silent.

Touch runs the other way: for someone who can't hear an alarm, vibration is the only channel there is. The alert and the all-clear carry two different rhythms — urgent pulses against one long steady note — learnable by feel, so the two are never confused.

And every alert arrives in the reader's own language, because an instruction you can't read never reached you.

Equipment that answers two questions.

Where is it, exactly — "reception, behind the desk", not "somewhere on Level 1" — and does it still work. Pads expire. Kits get used and nobody says so. A locked cabinet at 9pm is furniture, so the register records the code's home too.

Anyone can report an item missing, used or damaged in one tap, and it reaches whoever runs the building the same day — not the next service visit.

One thing this never becomes: a list of what people carry. That's a diagnosis in disguise, and it stays private, always.

Why sign-ins expire.

A visitor who signs in and never signs out is counted forever — and a building whose count only grows never reads as clear. So every sign-in carries a leaving time and expires on its own. No app, no reminder, no stale ghost in the count.

The one scan does three jobs: it signs them in, shows them the exits and the assembly point, and makes them reachable if something happens while they're inside. When it expires, all three end together.

And if their host goes home first, the building flags it — the visitor nobody remembers is still owed a way out.

Try the sign-in →

A channel is a room, not a person.

The alert lands in the channels your team already has open — no rollout, no new app to mandate on day one. One tap in the message says "I'm safe", and the count rolls up by team, live.

One honest detail: posting to a channel counts nobody. A message seen by a room is not a person accounted for — only the tap is. That's why the button is in the message.

See it in Slack and Teams →

What's actually in the black box.

The full timeline. Every person — including everyone who never answered. Every area and who cleared it. Every disagreement between the two counts, written out in sentences. Nothing summarised into comfort.

It's sealed the moment the event closes: change one character years later and the seal breaks visibly. The same drill always produces exactly the same document, which is what makes "is this the real one?" answerable.

Anyone can check it — a regulator, an insurer, a parent — in seconds, with no account. A check that needs a login is one a regulator never runs.
