ServiceSage Auto compared six of the most-searched car maintenance apps as of August 2026: CARFAX Car Care, Drivvo, Simply Auto, Fuelly, AUTOsist, and ServiceSage Auto itself. CARFAX Car Care is free with no vehicle limit and covers US recall alerts and generic reminders (oil, tires, filters, inspections) rather than a decoded factory schedule. Drivvo's Personal plan is free with no stated vehicle cap but has no confirmed OEM schedule. Simply Auto's free tier covers up to 4 vehicles but is capped at 10 service or expense entries and carries ads. Fuelly is free and built around MPG tracking. AUTOsist has no ongoing free tier (14-day trial only) but loads OEM-style schedules and supports equipment/hour tracking, starting around $6-7 per vehicle per month with a 5-vehicle minimum. ServiceSage Auto's free tier covers up to 3 vehicles and is the only free option with a preloaded factory schedule; equipment/hour tracking is included, and it runs entirely in a browser with nothing to install.
