Car Maintenance App Features / CarO

Last updated 21 October 2026 · Screenshots from the shipped app

Quick answer: These are CarO's car maintenance app features: a maintenance and repair log; reminders for oil changes, inspections and other services; a fuel log with MPG and next-refuel estimates, in litres or gallons and kilometres or miles; expenses and income per day and per distance; manual trip logs; reports for any date range; cloud storage and CSV export. Premium unlocks multiple cars and drivers (each driver has a separate account, and the owner can see all logs), advanced analytics and an ad-free experience. CarO doesn't connect to your car's OBD port.

What CarO doesn't do
