Getting Started

Everything you need to know to get started with Co-oto, whether you're an owner or a borrower.

What is Co-oto?

Co-oto is a mobile application that allows you to share a vehicle among close ones by automatically and fairly calculating costs for each user.

The problem Co-oto solves

Sharing a vehicle among multiple people often raises tricky questions:

  • Who owes how much at the end of the month?
  • How to split fixed costs (insurance, maintenance)?
  • How to know who used the car and when?
  • How to avoid money-related conflicts?

Co-oto automates all of this by offering a transparent system where everyone sees exactly what they owe.

How it works

The owner creates a group

Configures the vehicle, price per km and monthly fixed costs.

Borrowers join

They receive an invitation code to access the calendar.

Booking and usage

Automatic calculation

Co-oto calculates the fuel cost and the share of fixed costs.
