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 (up to 25 drivers and 10 vehicles per account).
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 kilometre, fuel fill-up and fixed cost turns into a fair, automatic split. No spreadsheet, no awkward maths.

- Automatic cost breakdownEach trip is split into usage (fuel), depreciation or leasing, and fixed costs.
- Per-kilometre rateSet a fair rate per kilometre so usage is billed consistently for everyone. You can also add an hourly rate.
- 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.
- Balance: who owes whatSee each member's balance at a glance, then confirm a refund and reset to start fresh.
- Multi-currency and unitsPick the currency per circle, kilometres or miles, litres or gallons.
Trips and logbook

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.
