Koast: Car & Motorcycle Convoy
Group GPS and push-to-talk
Free · In‑App Purchases
New: Koast opens on its own on your vehicle's CarPlay screen. Your whole crew live on one map, one button to talk, and navigation for everyone.
Ride in convoy, your whole crew live on the same map.
Koast is the convoy app for car and motorcycle groups: watch your crew move in real time, talk to them with one button, and let navigation guide everyone on the same route. For rides with friends, clubs and car meets.
RIDE TOGETHER, LIVE
- Real-time convoy map, with each member's name under their vehicle.
- Push-to-talk: talk to your group with one button, like a walkie-talkie. Your music lowers instead of stopping.
- Destination shared by the leader, and everyone's arrival time.
- Cohesion radar: is the group together or strung out? Optional alerts when someone drops off, with an arrow to get back.
- Quick messages, translated into each rider's language.
NAVIGATION AND MAP
- Turn-by-turn voice guidance, lane guidance, color-coded traffic and multiple stops.
- Speed limit shown, with an alert if you go over it.
- Twisty or scenic loops, a ride planner and Koast, the hands-free voice assistant.
- Fuel prices and the cheapest station on your route.
- Community hazard reports, with votes to keep the map up to date.
- Offline maps and nearly 20 map styles.
- CarPlay: Koast opens on its own on your vehicle's screen, even when the app is closed, with map buttons and the speed limit.
YOUR CREW
- Private or public crews, chat with photos, a pinned announcement and albums.
- Meets with RSVP and automatic reminders.
- A room for each country to find people who ride.
- Social feed, profiles, build sheets and ride photos.
YOUR VEHICLE
- AI skin: Koast turns 1 to 4 photos of YOUR vehicle into your marker on the convoy map (with credits earned by riding, or included with Koast+).
- Garage: maintenance and reminders, documents in your glovebox, manufacturer safety recalls.
- Your odometer moves forward on its own with your rides.
- Printable show card for car meets.
SAFETY FIRST
Set your destination before you go, use a mount and voice guidance, or let your passenger handle the app. Koast does not encourage speeding or racing: points reward distance covered, never speed.
YOUR DATA
Our database is hosted in Canada (ca-central-1 region). To run the app, some providers, mostly in the United States, also process information outside Quebec and Canada; the privacy policy names each of them. In the background, your location is only tracked during a ride, or while Koast is shown on your vehicle's CarPlay screen. Outside a ride, it is never shared with your crew. No advertising data, nothing is sold, and you can delete your account in the app.

Ride well, ride together.
Koast now starts on its own in CarPlay, even with the app closed, and picks your navigation back up when you plug your phone in again mid-ride.
On the vehicle screen: real map buttons, your speed and the speed limit in clear view, and a speed that goes back to 0 as soon as you stop.
Crew voice reconnects on its own after a network drop, and tells you why when it can't.
Permission requests now come in English and French, matching your phone's language.
Plus lots of small fixes for smoother rides.
