Private car sharing

Share a car without arguing about fuel money.

Sharing a car as a couple, with flatmates, family, colleagues or on vacation? Romy’s Garage keeps track of trips, costs and bookings and settles up fairly: whoever drives more pays more for fuel, and everyone shares the insurance equally.

Balance of a shared VW Polo: who pays whom

What the app takes care of

Everything about a shared car that otherwise ends up on scraps of paper, in group chats and in people’s heads.

  • Start Trip, End Trip

    Log trips with the odometer in two taps. The last reading is already filled in, even offline.

  • Costs split fairly

    Fuel and charging by distance driven, insurance and car tax in equal shares. Automatically per cost type.

  • Calendar without double bookings

    Who needs the car when? Reserve it in the shared calendar and everyone sees it right away.

  • Balance and Settle Up

    Who owes whom, at a glance. “Settle Up” closes the period so you can start fresh.

  • Invite by link, code or QR

    Members join with one tap. People without the app ride along as guests; others log their trips.

  • Where is the car?

    When you end a trip you can save where you parked. Optional, and deleted after 60 days.

  • Scan receipts

    Take a photo of a fuel receipt and the amount and litres are read on your iPhone. The photo is never uploaded.

Step 1

Hit the road in two taps

Tap “Start Trip” before you drive and “End Trip” afterwards. You only confirm the odometer, because the last reading is already there. If someone forgot to log a trip, the app spots the gap and asks: “Who drove?”

Step 2

Who drives when?

Everyone reserves their times in the calendar. There are no double bookings, and the others get a notification when someone reserves the car.

Step 3

Split fairly, to the cent

Whoever fills up adds the cost. The app splits it by the right rule and the balance shows who owes whom how much. At the end of the month you tap “Settle Up”, send each other the money and start again from zero.

Balance with the payments needed between members

What the app deliberately doesn’t do

  • No payments in the app. It does the maths; you send each other the money.
  • No GPS logbook, no tracking. Only the parking spot at the end of a trip, and only if you choose to save it.
  • No tax mileage log, and no insurance or tax features.
  • iPhone and iPad only. Anyone without an iPhone rides along as a guest.

Frequently asked questions

Does everyone need to pay for the app?

No. Only the person who adds the car pays. Everyone else uses car sharing for free.

What if someone doesn’t have an iPhone?

They are added as a guest. The others log their trips and costs, and they count in the balance like everyone else.

What about trips without an odometer reading?

You can add a distance afterwards. It counts in the settlement just like trips logged with the odometer.

Can the car also be a restoration project?

Yes. The app creates a linked project with name, model, year, odometer and photo in one tap.More about restoration
