Co-oto

The app enables owners to lend their vehicle to people they trust, handling bookings, mileage tracking, and cost splitting within a single mobile interface. Users add a car, invite friends, neighbors, roommates, or small work groups, and schedule usage through a calendar that records each trip and associated expenses. All calculations for fixed and variable costs are performed automatically, and participants can upload receipts and view the full history of trips and payments.

Target audiences include families sharing a household car, neighbors or friends pooling a vehicle, roommates managing a flat‑share car, and small businesses or associations that need a simple way to allocate fleet usage. The platform emphasizes transparency and control, allowing each member to see detailed trip data and cost distributions.

The service is offered on iOS and Android at no charge, with no commission taken from borrowers. A web dashboard is available for team‑focused users, providing statistics and export options. The software is currently in an experimental maturity stage.
