One App for Multiple Cars and Drivers

Written by Muneeb Rana · Last updated 21 October 2026

Quick answer: CarO is an app for multiple cars and drivers. Add every vehicle in the household or small business, and CarO keeps services, fuel, reminders and costs separate for each one. Each driver has their own account. The owner can see all of their logs.

TL;DR

  • Every car with its own history, reminders and costs.
  • Each driver has a separate account.
  • The owner can see every log.

CarO is built as an app for multiple cars from the start: one place for every vehicle and every driver.

All your cars, one app
All your cars, one app

How it works

  1. Add each car with its details and odometer.
  2. Give each driver their own CarO account. Logs sync through the cloud, and the owner can see every fuel, service, expense, trip and odometer entry those drivers add.
  3. Log fuel, services and costs against the right car.
  4. See reminders and reports per car, or across every car, for any date range.

Who it's for

  • Families: parents and teen drivers sharing two or three cars (multi-car maintenance apps).
  • Couples: one record per car, both can log.
  • Small businesses: a few vans or cars with several drivers. For inspections and work orders, see fleet maintenance apps.

Per-car costs

Comparing cars side by side shows which one costs most to run, useful when deciding which to replace (car expense tracker, cost of car ownership calculator).

Schedules for each car

Build a schedule for each vehicle with the maintenance schedule tool, and read the fleet maintenance schedule guide if you run vehicles for work.

Download CarO free on the App Store or Google Play. Free with ads; optional in-app purchases.
