The idea in twenty seconds: who books, who drives, and how the costs split themselves.
The three questions every shared car raises, answered in the app.
"Who has the car on Saturday?"
Book the car in a few taps. Everyone sees who has it and when, so nobody walks out to an empty parking spot.
"How much do I owe you?"
Fuel, insurance, maintenance: Co-oto splits them according to each person's use and shows who owes what.
"Where's the car parked?"
Pin where you parked, and every trip lands in a digital trip logbook that is always up to date.
Co-oto Teams keeps the app your drivers already use and gives you a web console to run the fleet.
« The app offers exactly what we need for our shared company car: reservations, trip log and vehicle location. It's the best solution we've found. »
Raphael (Switzerland) Co-oto is designed for anyone who wants to share a vehicle with trusted people.

« Co-oto is the only app I could find that is specifically designed for private share vehicles (as opposed to carpooling or commercial car sharing). I live in an ecovillage in a small town in Australia, and one of my neighbours and I have decided to share an EV. Your app has been super helpful in terms of booking the car and tracking our kilometres and expenses. Thank you! »

« As soon as we started sharing a car, we began using Co-oto and it has really helped us. The app is so practical day to day, the booking schedule is simple and clear, and I especially like the map that makes it easy to see where the car is parked. It saved us from constantly texting each other. One tap and we know whether the car is free and where it is.
Another big plus: managing the costs. We dreaded settling up at the end of the year, but with the app everything happens automatically. We saved time and avoided spending an evening working out who had paid more or driven more kilometers.
It's a really well-designed app, easy to use, and it genuinely makes sharing a car easier. I recommend it without hesitation! »

« We are a family of 5 users sharing 1 car. We tried several apps... Only this one really convinced us. Easy to use and all essential features work perfectly. And when there are problems, contacting the developer team is easy, always with friendly, solution-oriented responses. »

« Being craftspeople in the city means adapting to the urban environment, and pooling delivery resources is a sensible answer. We are seven small businesses sharing a single delivery vehicle, and it works day in, day out. »

Co-oto is a private car sharing app for a circle of people who already know each other: a family, flatmates, neighbors, friends or a small team. One vehicle, several drivers, and everything the arrangement needs in one place. A shared calendar shows when the car is free, trips are recorded from the odometer, and running costs are split according to how much each person actually drives.
It is not a rental marketplace and it is not carpooling. Nobody rents anything out and nobody makes a profit: fuel, insurance, servicing and depreciation are simply divided between the people who use the car.
Drivers pay nothing to use Co-oto and the app takes no commission on what circulates inside a circle. You can set up a vehicle and try everything for 21 days without creating an account, on iOS and Android, in eight languages.
The questions we hear most often.
Your insurance contract remains the reference for authorized drivers. For regular use, declare them to your insurer. Co-oto does not replace your coverage.
Insurance in the FAQYou send them a link. Free download, no commitment, uninstall anytime.
How it worksOne subscription per circle, valid for everyone. Any member can subscribe. 21 days free to try, no credit card or account required.
See pricingCo-oto calculates the split. Reimbursements happen between you as they do today (bank transfer, cash or payment app). The history serves as shared proof.
Cost sharing in detailNo. Everyone reimburses their share of real costs: fuel, insurance, maintenance. No markup, no income: it is cost sharing, not renting.
Co-oto vs rental platformsNo. No box, no tracker. You note the odometer, or let your phone measure the distance by GPS: the route stays on your phone, the circle only sees the kilometers.
GPS measurement in detailCo-oto Teams handles up to 10 vehicles and 50 drivers, with a web dashboard and Excel exports. Your drivers use the app on their own smartphones, with no hardware to install.
