AUTOsist is a solid maintenance and fleet record-keeper. If you're a hands-on owner who wants fault-code history, EV-aware schedules and a browser-first app with a free plan, here's an honest look at how MyDIYGarage compares.
AUTOsist is a well-established vehicle and fleet maintenance app with service records, reminders, inspection forms and document storage. It's a capable product, especially for small fleets and asset tracking. If that's your need, it's a fair choice.
MyDIYGarage is aimed at the individual DIY owner and enthusiast: the person who does their own oil changes, reads their own OBD2 codes and wants one searchable history per car — including EVs and track days.
