The radios
The walkie-talkies reach the next hill, not the next valley. Half the convoy hears half the message.
Voice, a live map and the route for groups that go off-road together. On the phone you already have.

The walkie-talkies reach the next hill, not the next valley. Half the convoy hears half the message.
Nobody reads it with gloves on at 30 km/h. And it doesn't show where anyone is.
A GPX file sent the night before, opened on four different apps. One car has it right; the others follow the dust.
A wrong fork, and two cars are on another track with no idea where the rest went.
Someone is bogged at the back. The front finds out at the lunch stop.
One app, for the whole list.
One channel for the group. Press, talk, everyone on the channel hears, wherever there is signal. No licence, no antenna, no range limit.

Who's ahead, who stopped, who took the wrong fork. Every car that shares its location, while it is on the channel. Tap one to see how far it is and when it was last seen.

Load the GPX once, share it to the channel, and everyone follows the same line. Once started, it keeps guiding you with no signal.

Hold the emergency button: your position reaches everyone in all your channels, your open mic everyone on the channel. Send an alert with a photo for anything smaller.

Most groups need one channel. Clubs and bigger rides add a couple.
Everyone. The day's talk, the route, the photos.
The first and last car, and whoever is running the day.
Your own car and the two you always ride with.
The recovery truck, the mechanic, the lunch stop.
Everyone joins for free. On Free you are live in one channel at a time, so stay on Convoy while driving. The person who creates the channels on Core removes the member cap and can listen to several at once.

One person imports the GPX and shares it to the channel. Everyone sees the same line on the map; nobody re-sends a file.
Start navigation and the app guides you along the track itself, not along the nearest road. Waypoints become checkpoints: the viewpoint, the fuel stop, lunch.
Drift more than about 45 metres from the track and the app warns you. It does not reroute you onto a road: it brings you back to the line.
Once navigation has started it needs no network. The route, the checkpoints and your position stay. The background map may be blank: your phone only shows the map it kept from earlier use.

Hold the button for one second. Five seconds to cancel, then your position goes to everyone in all your channels and your live microphone to the channel you are on. Their phones sound an alarm; on iPhone, even in Do Not Disturb. It needs signal at the moment you press.
A text, a photo and your position, pinned on the map for everyone. "Deep water at the ford." "Gate closed, go around."
Someone not answering? Ring the channel, or one person if they are your contact. Their phone rings again every 15 seconds for two minutes, until they answer.
Bloodhound points a live compass at any car on your map, with the distance. Follow it until you are back together.

Off-road is where mobile signal is thin. We would rather you know this before the ride than during it.
Voice, the live positions of the others, photos and video, and anything you send: the emergency button, alerts, ring, messages. Nothing waits to be sent later. What is said while you are out of coverage is not heard.
The route guide once started, your own position on the route, the recording of your trail (it uploads when you are back), and the chat you already loaded.
Agree the next checkpoint on the channel. Set the channel to keep locations while disconnected: a car that loses signal then stays on the map where it was last seen, and comes back on its own when the signal does.
One person on Core lifts the member cap for the whole group. Whoever wants to hear two channels at once needs Core too.
Follow the route with navigation on and your drive is recorded; replay it after. To hand a new way to the next group, record it as a route and share that.
The river crossing, the view from the top, the car that needed the winch. In the channel, where everyone finds them next week.
