RoadTripKit

Road trip games for the whole car.

RoadTripKit is a set of road trip games that every phone and tablet in the car can join with one short car code. Each kid plays at their own level, and points from every game land on one family scoreboard.

I started it for our family’s spring break drive in 2026 and rebuilt it this fall. A grown-up runs the trip from a co-pilot console, with screen-time limits, quiet hours and approvals, and the games keep working with no signal.

What’s interesting about it

Works with no signal

Every device keeps playing offline. When phones reconnect, their changes merge: points earned on two phones add up, and a plate found on either one counts.

Location stays on the phone

State-line stamps come from GPS, checked on the device against built-in state borders. The location never leaves the phone.

No accounts

A family is a car code, not a sign-up. Each kid picks a four-number or four-picture code, which keeps siblings out of each other’s points.

AI only where it helps

In the iPhone app, Claude writes fresh trivia rounds, Mad Libs and a story chapter for each state line. The browser version plays built-in questions and stories, so it never calls the AI.

Questions

What is RoadTripKit?

RoadTripKit is a set of road trip games for families: License Plate Hunt, Road Bingo, live trivia, puzzles and more. Every device in the car joins with one car code, and points go to one family scoreboard.

Does RoadTripKit need a cell signal?

No. The games keep working offline, and changes from each device merge when the signal comes back.

Do I need an account?

No. A grown-up sets up the family once, and every other device joins with the car code.

Is RoadTripKit free?

Yes, playing in the browser is free. An iPhone and iPad app is coming soon.

Who built RoadTripKit?

Jon Olson, a product leader in Carmel, Indiana. He built it with Claude Code for his own family’s road trips.
