Dispatch / CAD API
Your CAD sends a call straight to a unit’s phone. One tap starts the route. Status flows back automatically.

Navigation for ambulance crews
Get your crew to the door. Not just the block.
Routes that skip rush-hour turn bans. The exact house, on the right side of the street. A live map of every unit for your dispatchers.

The problem
The clock keeps running after the ambulance reaches the block.
13:09
Average time from a 911 call to arrival at life-threatening medical emergencies in NYC (FY2026). Up 3 min 50 s since FY2015.
NYC Comptroller, Oct 16, 202628%
Of real response time is spent between pulling up and reaching the patient. A median of 2.1 minutes.
Silverman et al., Acad Emerg Med 2007 (449 NYC calls)−11%
Lower odds of good neurological survival from cardiac arrest for every extra minute of EMS response.
Goto et al., J Am Heart Assoc 2018 (553,426 patients)Where the seconds go: the wrong side of the street and a loop around the block. A no-left-turn sign a civilian app obeys. A long one-way, stuck behind a double-parked truck. A new EMT who has never driven the neighborhood.
Why consumer GPS falls short
Consumer GPS routes an ambulance like a civilian.
ResponseOne routes it like a medic who knows the streets.

Turn bans
Obeys rush-hour bans like “no left 7–10 AM”.
Responder mode skips congestion turn bans.
One-way streets
Sends a rig down a long one-lane one-way.
Avoids one-lane one-ways of 1,800 ft or more. Short ones only when faster.
Arrival
“Destination on the right,” somewhere on the block.
Feet countdown, left or right, the house number you’re passing, and a photo of the building.
Corner buildings
Ends on the entrance street.
Picks the fastest end point: front street, corner or cross street.
Hospitals
A generic search result.
Closest hospitals by drive time, filtered by specialty.
Dispatch
Nothing. The crew calls in.
A live map of every on-duty unit, and a one-tap “I’m on scene”.
Responder routing
Routes that think like a Brooklyn medic.
The crew picks Responder or Regular for each trip. Responder mode applies rules learned on real calls before the rig moves.
- Skips congestion turn bans. “No left 7–10 AM” doesn’t stop an ambulance. Other restrictions stay.
- Avoids long one-lane one-ways. Stretches of 1,800 ft or more are avoided. You can get stuck behind one car.
- Prefers two-way avenues. One lane each way beats two lanes one way. There’s room to get around.
- Few turns, especially lefts. Turns cost time. The route reflects it.
- Always offers a streets route next to any highway route, with the time difference.
ResponseOne responder routeConsumer GPS
The last 500 feet
The exact house. Not “somewhere on the right.”
On the final block, ResponseOne switches to arrival mode. The crew knows where to stop before they get there.
- Distance in feet. 600, 400, 200, 100, 50.
- Left or right, checked twice. Shown only when the route and NYC address points agree. A wrong side is worse than none.
- The house number you’re passing next to the one you need.
- A photo of the building, so the crew knows what to look for.
- Corner buildings: ends at the corner or on the cross street when that’s faster.
For the company
Every unit on one live map. Only your units.
Each company gets its own dispatch view. Status, ETA and last update for every on-duty unit, refreshed every 5 seconds.
- Isolated by company. Enforced on the server. A dispatcher never sees another company’s rigs.
- On duty / off duty. A unit shares its position only while on duty. Off duty, dispatch sees nothing.
- One tap: “I’m on scene.” Texts the dispatcher from the crew’s own phone.
- Your admin hands out the keys. Each code locks to one phone. Revoke it in a second.
Dispatch / CAD API
Your CAD sends the call. The crew taps once.
A documented REST API for any dispatch system with an open API. The call pops up on the unit’s phone. One tap starts the route.
- Send a call to a unit with an address or coordinates, priority and notes.
- Status comes back by itself. En route, on scene, transporting, available. Signed webhooks.
- Per-company API keys. Created and revoked by your admin. Stored hashed.
- Idempotency keys and rate limits built in.

Everything else a crew needs
Built for the call, not the commute.
Shared closures
One crew blocks a street. Every unit in the company routes around it within a minute. Blocks expire after 4 hours.
LiveClosest hospitals
Ranked by drive time from the unit. Filter by trauma, thrombectomy stroke, cardiac, burn, pediatric, L&D or psych.
Voice that names the corners
Spoken turn-by-turn with intersection callouts. Tap the banner for the next steps.
Open from any message
Tap an address in a text or WhatsApp. ResponseOne opens straight into the route.
Licenses you control
One license per ambulance. Codes lock to one phone. Suspend a company and it’s locked out within a minute.
Works in dead zones
No signal? The active route and map stay on the phone. The crew sees “Offline — using saved route” and keeps driving.
LiveKeeps guiding in the background
Switch to the phone or the patient app. A mini map keeps the route going, with voice.

Routing covers the whole metro area. Side-of-street checks use NYC address data, so they’re sharpest in the five boroughs.

Does it replace our CAD?
No. It works next to it. Your CAD can send calls straight to a unit through the Dispatch API, and unit status goes back to your CAD.
Does it tell crews to break traffic laws?
No. Responder mode only skips congestion turn bans, like “no left turn 7–10 AM”. It never routes the wrong way down a one-way. It gives guidance; crews follow their agency’s emergency vehicle policy and the law.
Do you track crews when they’re off duty?
No. A unit shares its position only while it is on duty, and only with its own company.
What phones does it run on?
Android, iPhone and any modern browser. No extra hardware.
Where does it work?
New York City, Long Island, Westchester and New Jersey. It was built and tuned on Brooklyn calls. Side-of-street checks use NYC address data, so they’re sharpest in the five boroughs. Elsewhere? Ask us.
How is it priced?
Per ambulance, per month, billed yearly: $49 for 25–49 ambulances, $44 for 50–99, $39 for 100–249, $34 for 250+. Dispatchers and admins are free.
What does the pilot cost?
Nothing. 30 days, 10 ambulances, one base. We agree on the success measures before it starts.
How fast can we start?
Setup takes a day. Crews install and sign in within minutes.
