- You don't need inspections, work orders or a web dashboard.
- You want to start free.
Where AUTOsist is the better fit
- You need inspections (DVIR), work orders and technician workflows.
- You want a web portal for office staff.
- Your fleet is growing or regulated (fleet maintenance schedule).
Which should you choose?
Start with the simplest tool that covers your obligations. If that's a phone app per vehicle and driver, CarO is enough. If you need compliance records and work orders, AUTOsist or another tool from fleet maintenance apps is the right step. Estimate per-vehicle costs with the cost of car ownership calculator.
Switching apps
Most apps let you export your data (CSV or a report); check the export option in settings before you switch. Re-enter your current odometer, upcoming service dates and any open reminders first, then add history as you need it. Keep your old receipts or vehicle maintenance log either way.
Download CarO free on the App Store or Google Play. Free with ads; optional in-app purchases.
