Jump the pale cacti and rocks — one hit ends the run. The dark dips are safe, so let the car run over them, and grab the wrenches for a quarter kilometre each. A green double-arrow banks a double jump — press again in mid-air to spend it.
Double jumps. A green double-arrow badge banks one double jump, and they stack — the counter in the corner of the scene is how many you are holding. Press jump again while you are in the air to spend one. You get one per jump, so a second badge is a second jump, not a higher one.
The car drives itself and speeds up as you go. Your score is the distance on the tripmeter, which is the only thing this has in common with the actual app. Wrenches are worth +0.25 km and cannot hurt you; some sit on the road and some need a jump. There are five legs and three stages: the landscape turns over at 4, 9, 15 and 22 km, and each stage ends at a finish arch — drive through it and the pace eases off for a moment before building again. Reach the last arch at 30 km and you have finished the rally; go again and it comes back faster.
A rally trip computer for iPhone, Apple Watch and CarPlay. The distance, speed and timing instruments a co-driver works from, on the car's own screen — big enough to read at a glance and at arm's reach on a rough road.
Tripmeister is built for classic, regularity and orientation rallying: two independent trip odometers with 10 m resolution and instant nudge/set/undo, speed and average speed, your ahead-or-behind delta against a target schedule, compass heading, altitude, stage timers and a rally clock — plus full GPX and CSV logging of every stage you drive.
The same measurement engine drives all three. The phone is where the co-driver works, CarPlay is what the driver reads, and the standalone box runs the stage with no phone in the car at all — the same distance, the same delta, the same stage time, because it is the same code.
Everything is measured on device. No account, no server, no internet connection. Your tracks stay on your phone unless you export them yourself.
Tripmeister is meant to be open, and it will be. The repository is closed for the moment while the iOS app works its way through beta and App Store review — that is a timing decision, not a change of plan.
The reason it matters here: a trip computer asks you to trust a number you are navigating by. The measurement engine is a separate, UI-independent component with its own test suite — recorded GNSS fix streams are replayed through the same distance integration, accuracy gating and dead-reckoning that runs in the car, so a change that would quietly shift your distances fails a test instead of showing up on a stage. Every feature traces back to a written requirements spec with a numbered ID that the commits cite. That work is only worth anything if you can eventually check it yourself.
Want to be told when the source goes up? That is the same waitlist below — say so in a reply and you will hear about the repository as well as the hardware.
In TestFlight beta. The engine is complete and tested; the app around it is filling in. CarPlay needs an entitlement that Apple must approve, so until that lands the beta runs on iPhone and Apple Watch.
You can be on it. Everyone who joins the waitlist gets a TestFlight invite.
Rough order, not dated promises.
A phone on the dash is not a rally instrument. The plan is a proper dash-mounted
head — a bright, readable display with real detented controls you can find with
gloves on and without looking away from the road — driven by the same
RallyeCore engine.
Two ways to get one, once they exist:
Neither is available yet, and nothing is being taken in payment. The waitlist is how the first batch gets sized and how you hear about it first.
Sign up and you get a TestFlight invite to the iPhone beta. It arrives by email from Apple, and you accept it in Apple's TestFlight app. Use the address your Apple ID is on, so the invite lands somewhere you can open it.
After that, one email when there is something real to say — the hardware when it is ready. No newsletter, unsubscribe in a reply.
