The drive

You get on the Turnpike at 6:40.

Your detector is paired and quiet. Kaltrix is already watching the road ahead of you through every other driver on it.

Ka band

Two miles up, someone else's detector goes off.

It lands on your map before you can see the overpass it came from. Band, distance, and how many drivers have confirmed it.

Aircraft

A plane is circling the next stretch.

Low, slow, and turning over one piece of highway. No detector on earth can hear that one. Kaltrix reads it off live aircraft traffic.

Hazard

Debris in the right lane, called in four minutes ago.

Reported by a driver ahead of you with one tap. You move over before you are on top of it.

Arrival

You get there nine minutes under the estimate.

The whole run is saved: the route, your speed second by second, and every detection you drove past.

Every drive ends with something worth keeping.

Kaltrix records the route, the speeds and the detections you passed, then hands you a recap card clean enough to send to someone.

Replay it second by second

Scrub the whole drive with speed colouring and a blip for every detection you passed.

Compare against the estimate

Planned arrival against the real one, so you can see where the drive actually went.

Put your car behind it

Drop in a photo and drag the route where you want it, or send the plain card. Either way it is built for a group chat, not a spreadsheet.

Four things the map is watching while you drive.

Each one arrives differently, and each one is drawn so you can tell them apart at a glance without reading a word.

Radar

Ka, K and laser, straight off paired detectors and confirmed by the drivers behind them.

Aircraft

Planes and helicopters flying low and circling one stretch of highway, read off live traffic.

Hazards

Debris, stopped vehicles, crashes and construction, called in by drivers a few minutes ahead.

Your route

Turn by turn with lane guidance, so warnings land in the context of where you are going.

Saw something the network hasn’t? One tap.

Radar by band, road hazards, and the two things no detector can hear: a police helicopter or a plane working the highway above you. Reports are anonymized the moment they leave your phone.

It belongs on the dash, not in your hand.

  • CarPlay and Android AutoThe full map on the car screen, with alerts, reporting and destination search. Not a stripped-down list.
  • Spoken before it is seenBand and distance are announced while your eyes stay where they belong.
  • Runs with the phone lockedThe drive keeps recording and the car display keeps moving.

Setting it up takes about a minute.

Pair the detector you already own

Kaltrix connects over Bluetooth to detectors that expose it, and works alongside every other brand through manual reporting. There is no new hardware to buy.

Drive the way you already drive

What your detector hears becomes map data for the drivers behind you, coarsened and stripped of anything identifying on the way out.

Get back more than you put in

One detector covers a few hundred feet of road. A few thousand of them cover the whole corridor, which is the entire reason any of this works.

Your drive stays yours. What the map gets is a place, not a person.

Shared detections are coarsened on the server and never tied to your account. Location draws your map and warns you, nothing else, and you can drive as a guest without an account at all. Read the privacy policy.

Run the next one before it ships.

Beta testers get new features on TestFlight first, and the Android build as soon as it opens up. Leave your email and we will send the invite.

Testing on

No spam — just TestFlight invites for early builds.

Take the next drive with the road already read.

Free on iOS 16+. Works with or without a radar detector.
