DriveStream records every drive automatically. When a convoy finishes, each driver has a complete log — route at 1 Hz, total distance, moving time and top speed — accessible on the phone and in a web companion.
Most convoy apps are live-only tools. When the trip ends, the map clears and the moment is gone. DriveStream builds a history behind every trip. If you take the same mountain route twice a year, two summaries sit next to each other for comparison. If you're working toward a rank, every kilometre from every drive carries forward.
What gets recorded
The GPS route is captured once per second. That resolution is enough to show the exact line through a switchback, the point where the convoy compressed behind a slow truck on a two-lane road, or where one car took the wrong exit and had to double back. Alongside the route, the app records total distance, moving time and top speed.
Moving time is the figure worth understanding. It strips out stationary time — rest stops, fuel fills, a lunch that ran long — and gives you the actual driving time for the trip. The difference between total elapsed time and moving time makes the shape of a long day on the road clearer than either number alone.
Top speed is a personal record that updates whenever a new drive beats the previous best.
Replay
The replay puts the cars back on the road map and moves them at their recorded speeds. A scrubber at the bottom of the screen lets you jump to any moment in the trip. Playback speed runs from 1× up to 300×, so even a day-long convoy can be watched from start to finish in a short time. Stop locations appear separately from driving time, so you can see exactly how long each pause added.
Animated replay: jump to any point with the scrubber, or play at up to 300×.
Replay is where you notice things that went unseen during the drive. The gap between the front and back of the convoy stretched on the long downhill. Someone was running consistently further back than the others. A car stopped for several minutes at a junction before the rest of the group caught up. For a route you drive regularly, two replays from different dates show whether the road is getting busier or your pace has changed.
The replay is also the practical answer to one of the common frustrations of convoy driving: "what actually happened back there?" When a car got separated or the group lost contact for a stretch, the recorded route makes it possible to reconstruct the sequence afterwards.
The ranking system
Every kilometre from every drive adds to a rank that runs from Rookie to Legend. Legend is at 40,075 km — Earth's circumference — which makes it a real long-term target for anyone who drives regularly, rather than a figure set to be unreachable. There are no friends lists and no leaderboard; the climb is entirely between you and your own accumulated distance.
The convoy view
During the drive, the convoy list shows each car's gap to the one in front, speed, fuel level and phone battery — the information that matters when you're trying to hold a group of vehicles together across a long route.
The convoy list: gap to the car ahead, speed, fuel and battery for every car in the group.
A shared destination can have multiple stops — a viewpoint, a fuel station, a restaurant for dinner, a hotel for the night. The convoy tracks everyone through each stop, showing who has arrived and who is still on the way. In the drive replay, those stops appear as distinct pauses in the route, which gives a multi-leg trip a clear shape rather than a flat line from start to finish.
CarPlay
The convoy map and turn-by-turn navigation work through CarPlay. Every car's position and the shared route appear on the dashboard screen during the drive. The phone stays in a pocket, and hands stay on the wheel.
What it adds up to
DriveStream builds a personal road-trip record without any extra effort. Each drive logs itself: the route, the stop times, the personal bests — going into a history you can replay and compare. The app has no ads, no analytics library, and location is shared only with the people in your convoy.
It's in beta for iPhone on iOS 26 or later. drivestream.app has the details.
