All the features to easily share your car
Co-oto transforms private car sharing into a simple and direct experience for people who already know each other (neighbors, friends, roommates, etc.). Ask your circle to identify people interested in sharing their car or wanting to borrow yours The size of the circle follows your plan: 1 vehicle and 2 drivers on the free version, 3 vehicles and 10 drivers on Plus, 10 vehicles and 50 drivers on Teams.
Together, establish the terms of your private car sharing agreement and install the app. You can then save money by managing your trips and expenses directly, all without intermediaries.
The core
Costs and expense sharing
Every kilometer, fuel fill-up and fixed cost turns into a fair, automatic split. No spreadsheet, no awkward math.
More on expense sharing- Cost simulatorEstimate a trip's cost before you go, with distance from start and destination address.
- Automatic cost breakdownEach trip is split into usage (fuel), depreciation or leasing, and fixed costs.
- Per-kilometer rateSet a fair rate per kilometer so usage is billed consistently for everyone. You can also add an hourly rate.
- Balance: who owes whatSee each member's balance at a glance, then confirm a refund and reset to start fresh.
Also included
- Fixed cost managementFold insurance, maintenance and other fixed costs into the calculation.
- Fuel fill-up trackingLog fill-ups: the amount and volume feed into each member's balance and the exports.
- One-time expensesAdd exceptional costs (repairs, inspection) that are split fairly between members.
- Split a trip between membersAdd co-travelers to a trip and the cost is divided automatically between everyone aboard.
- Multi-currency and unitsPick the currency per circle, kilometers or miles, liters or gallons.
- Per-booking flat feeCharge a fixed amount for every booking, whatever the distance. It is the one cost that can be due without a trip: the slot was held.
- Duration packagesTeamsSet two flat rates of your own, for example 2 hours and 5 hours. The app works out the hourly total and the package, then bills whichever is cheaper.
- 24-hour days from pickupCount days as 24-hour slices from pickup instead of midnight to midnight, so an evening-to-morning loan stays a single day.
- Bill the booked slotTeamsWhen a car comes back early, bill the slot that was held rather than the hours actually driven. A tolerance you set absorbs small early returns.
Trips and logbook
Record and classify every kilometer
A clean logbook that builds itself, trip after trip, and is ready to export the day you need it.
See the trip logbook- Odometer-based tripsAdd, edit or delete trips from the vehicle's odometer. No box to install.
- Odometer photo + OCRPhotograph the odometer and the mileage is auto-filled by image recognition. No hardware at all.
- Private or business tripsTag each trip as private or business, with a history filter and a dedicated column in the exports.
Also included
- Trip historyBrowse the complete, dated history of every trip taken with the vehicle.
- Change historyEvery trip and booking keeps track of who changed what and when. Full transparency between members.
- Monthly statisticsFollow vehicle usage and expenses month by month.
- Excel exportExport your trips, fuel fill-ups and reservations to a clean, dated Excel file.
- Record for another memberThe owner, or a manager, can log a trip, a booking, a fill-up or an expense for someone who did not have the app to hand. That member is notified, and the entry says who wrote it.
- Monthly recap by emailOn the first of the month, every active member gets the month just gone: trips, kilometers and shared costs. Nothing is sent if the circle did not move.
Booking and coordination
Organize who drives, and when
A shared calendar, reservations and notifications keep everyone on the same page, with no group-chat chaos.
- Shared calendarEveryone sees the vehicle's availability in real time and books their slot.
- Reservations and validationDrivers request the vehicle; the owner can validate when needed.
- Availability rulesBlock days of the week in advance, all day or on a time slot, and cap the maximum duration of a booking.
Also included
- Recurring reservationsSchedule automatic reservations for your regular, repeating trips.
- Notifications and remindersAlerts for reservations, trips and messages, with reminders before and after each booking.
- Built-in chatCommunicate directly with the members of your car-sharing circle.
- Vehicle locationNote where the vehicle is parked so the next driver finds it easily.
- Calendar sync (.ics)Add a reservation to your calendar in one tap, or subscribe to the .ics feed so Google, Apple or Outlook keeps itself up to date.
- Maintenance and renewalsService, roadworthiness test, insurance, winter tires: put the vehicle's deadlines in the shared calendar and get a reminder by notification and email before the date.
Ground rules and setup
Set the rules and make Co-oto fit your circle
Put your rules in writing, keep a photo record of the vehicle, then adapt the settings, vehicles and privacy so the app works the way you already share.
How to prevent misunderstandings- Circle charter23 ready-made rules across 5 categories, to tick and then complete with your own figures (deductible, deadlines) and your own house rules. Every driver accepts it before the first trip.
- Trip condition reportA guided walk-around at departure and on return. The photos sit side by side, and any fresh damage is reported on the spot.
- Multiple vehiclesManage several vehicles in the same circle, each with its own calendar and costs.
Also included
- Circle settingsBookings only, owner trips, cost display: a few settings are enough to make Co-oto fit the way your group already shares.
- All vehicle typesSet your engine type, petrol or electric, with charge tracking for electric vehicles.
- Privacy controlsControl the visibility of your activity and expense reports for other members.
- Circle managersAppoint someone to run the circle day to day: members, vehicles, and other people's entries. Rates, balances and the subscription stay with the owner.
- Who drives whatTeamsTick the drivers allowed on each vehicle. A car you leave alone stays open to everyone; a restricted one simply does not show up for the others.
- Vehicle out of serviceCar at the garage? Switch it out of service with a reason and, if you know it, a return date. It stays visible, but nobody can book it or start a trip with it.

Not familiar with private car sharing?
With the widespread adoption of shared mobility, terms like "car sharing", "carpooling" or "peer-to-peer sharing" are widely used but often confused. It's important to clarify and distinguish these practices, as they correspond to different concepts.
