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.
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
| Before | With Co-oto |
|---|---|
| "Who has the car?" — calls, texts, confusion | Shared calendar visible to everyone |
| Excel spreadsheet never up to date | A dedicated app, always in sync |
| "You owe me €40 for fuel" — tensions | Automatic cost splitting |
| "Where is it parked?" | Last parking location on the map |
| No record of trips | Complete history, exportable |
A typical week with Co-oto
James books the car for 7:30 AM — he's commuting to work. Emily gets a notification.
Emily takes the car for a doctor's appointment. She logs her trip in the app.
Their father uses the car in the afternoon to run errands. He notes that he filled up the tank.
James checks the stats: 120 km this month, Emily 85 km, their father 60 km. The app calculates each person's share.
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.

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.
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, paid only by the owner.
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.
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.
Only the owner pays. Drivers use the app for free.
