Sharing a car is simple, as long as you stay organized. Co-oto gives you a shared calendar, automatic cost splitting and vehicle location. Everything you need to make car sharing between trusted people work on a daily basis.
What to share with Co-oto?
Share a car with people you trust
"You took the car? I thought it was my turn."
This morning, James needed the car to drop the kids at school. But his sister Emily took it last night and forgot to mention it. Result: 20 minutes late, a frantic rush, and a tense conversation at dinner.
This kind of scene plays out in countless families, flatshares and neighborhoods every week. Because sharing a car is a great idea, but without organization, it quickly becomes a headache.
Co-oto is the app that solves this problem. No hardware to install, no commission, no strangers: just a simple tool to coordinate between people you trust.
- Free for drivers
- No commission
- No device to install
- Between people you know, not strangers
Why share your car?
A car sits parked more than 95% of the time. Meanwhile, it costs between 5,000 and 10,000 € per year: insurance, roadworthiness test, maintenance, depreciation, parking.
Many households own two cars, yet the second one is only used a few times a month. Sharing a vehicle with trusted people allows you to:
- Split costs between multiple users
- Avoid buying a second car that's underused
- Make better use of a vehicle that sits in the garage
And unlike peer-to-peer rental, you keep control: you choose who drives.
What changes with Co-oto

| "Where is it parked?" | Last parking location on the map |

A typical week with Co-oto
MON
James books the car for 7:30 AM, he's commuting to work. Emily gets a notification.
TUE
Emily takes the car for a doctor's appointment. She logs her trip in the app.
WED
Their father uses the car in the afternoon to run errands. He notes that he filled up the tank.
FRI
James checks the stats: 120 km this month, Emily 85 km, their father 60 km. The app calculates each person's share.
SUN
Emily wants the car for a day trip but it's already booked. She sees the slot in the calendar and makes other plans.
No arguments. No forgotten bookings. Everyone knows who uses what, when, and how much it costs.
How does Co-oto work?

Book, drive, done
Need the car? Check availability, book it. Others get notified. The app records trips and calculates costs.
Key features

Instant visibility on who booked and when.

Neighbors and friends
You don't use your car on weekends and neighbors or friends could use it? Share it with confidence.

SMEs and organizations
Tradespeople, sports clubs, associations: pool a cargo van or minibus.
Co-oto vs other solutions
Vs Turo / Getaround
These platforms organize rentals to strangers. You don't choose who drives, and the platform takes a commission on every trip. See the full comparison with Getaround, GoMore and Turo.
Co-oto is designed for sharing between trusted people: no rental, no strangers. No per-trip commission: Co-oto works on a fixed monthly subscription that any circle member can take out to unlock features for the whole group.
Vs carpooling apps
Carpooling shares a trip (multiple passengers, one driver). Car sharing shares a vehicle (multiple drivers, at different times).
Both are complementary.
Vs WhatsApp + Excel
It works... until someone forgets to update it, reimbursements pile up, or nobody knows where the car is.
Co-oto centralizes everything in an app built for exactly this. Co-oto, Excel, Splitwise and Tricount compared.
How much does it cost?
Co-oto offers a free version for occasional use (1 vehicle, 2 drivers, limited features).
For more intensive sharing, paid plans unlock all features.
One subscription per circle. Any member can subscribe, and the whole group enjoys every unlocked feature.
Frequently asked questions
Does insurance cover multiple drivers?
A car insurance policy covers the vehicle, not only its owner. Other drivers can be authorized, provided they are declared to the insurer. Contact your company to check the conditions and any extra cost, which is often modest between trusted people.
Do you need a written agreement to share a car?
It isn't mandatory, but it's strongly recommended. A simple document that sets out the usage rules, cost sharing and the expected condition on return avoids misunderstandings.
How do you split costs fairly?
Co-oto records each driver's mileage and automatically calculates their share of fixed and variable costs. You can split by distance, in equal parts, or by your own rules. The history is exportable for your records.
Is Co-oto really free?
Yes, for drivers, use stays free. A free version lets you get started (1 vehicle, 2 drivers). For more intensive sharing, a single subscription per circle is enough: any member can take it out and the whole group benefits. No per-trip commission.
