Car maintenance apps have exploded in number over the past few years. Some are genuinely useful. Many are bloated with features nobody asked for. A few are just glorified reminders apps with a car icon slapped on them. And nearly all of them are pushing you toward a recurring subscription for features that should be standard.

This comparison is honest — including about RevLog, which I built. Here's what each app actually does, who it's best for, and where the real trade-offs are.

What to Look for in a Car Maintenance App

Before the reviews, here's what actually matters in a good car maintenance app:

  • Easy logging: If it takes more than 30 seconds to add an oil change, you'll stop using it.
  • Reminders that actually work: Mileage-based, date-based, or both. Configurable for your vehicle.
  • Multi-vehicle support: Households typically have 2+ vehicles.
  • Cost tracking: To know what your vehicles are actually costing you.
  • Data export: Your records should be portable. PDF or CSV export is non-negotiable for resale documentation.
  • Privacy: Does the app require an account and upload your data to their servers? Most do. Some don't.
  • Pricing model: One-time purchase vs. recurring subscription significantly affects long-term value.

RevLog

Price: $14.99 one-time | iOS and Android

RevLog is built around one principle: every maintenance event should take less than 30 seconds to log. The interface is minimal — select vehicle, select service type, enter mileage, add cost and notes if you want, done. Reminders are mileage-based and date-based, customizable per service type per vehicle.

It supports multiple vehicles, logs service costs, and exports complete service records as a PDF. Data stays on your device — no account required, no cloud sync, no data uploaded anywhere. If you want, you can back up locally.

Pros:

  • One-time price — no recurring cost
  • Genuinely fast logging experience
  • Clean, distraction-free interface
  • PDF export for resale documentation
  • No account or internet required

Cons:

  • No automatic OBD-II sync
  • No social features or community
  • Smaller app compared to established players with larger feature sets

Best for: People who want a straightforward vehicle history log without subscription fees and without sharing their data with a third party.

Fuelly

Price: Free (with ads) | iOS, Android, Web

Fuelly has been around for over a decade and has one of the largest databases of real-world fuel economy data. Its primary strength is fuel tracking — you can compare your actual MPG to averages from other owners of the same vehicle. This is genuinely useful for spotting fuel economy degradation that might indicate maintenance issues.

The service logging is basic but functional. Reminders exist but are limited in customization. The app is free, ad-supported, and requires an account.

Pros:

  • Best fuel economy tracking and benchmarking against similar vehicles
  • Large, active community with real-world data
  • Free to use
  • Web access in addition to mobile

Cons:

  • Service logging is a secondary feature, not the focus
  • Ad-supported free tier is noticeably ad-heavy
  • Requires account — your data lives on their servers
  • UI feels dated compared to modern apps

Best for: Fuel economy obsessives and people who want to benchmark their MPG against other owners of the same vehicle.

Drivvo

Price: Free tier available; Pro ~$2.99/month | iOS, Android

Drivvo is one of the most feature-complete car management apps available. It tracks fuel economy, service history, costs, insurance, registration, parking, fines, and more. The reporting is thorough — you can get detailed monthly and annual cost summaries across all vehicle expenses.

The free version is functional but limited on reporting and vehicle count. The Pro subscription unlocks full features.

Pros:

  • Most comprehensive expense tracking of any app
  • Strong reporting and cost analysis features
  • Cross-platform with web backup
  • Tracks non-maintenance expenses (insurance, tickets, parking)

Cons:

  • Subscription model adds up over time
  • Feature depth comes with UI complexity — can feel overwhelming
  • Requires account and cloud sync

Best for: People who want deep financial analysis of their total vehicle ownership cost and are comfortable with a more complex interface.

CarFax Car Care

Price: Free | iOS, Android

CarFax is best known for vehicle history reports, and their Car Care app extends that into maintenance tracking. The app is free and integrates with your vehicle's VIN to pull in recall information and service history from CarFax's database (if available). It suggests maintenance based on your specific vehicle.

The trade-off is data sharing — CarFax is a data company, and using their free app means your vehicle data and maintenance patterns flow to their systems.

Pros:

  • Free with useful recall alerts
  • VIN-based vehicle setup pulls manufacturer service schedules
  • Integration with CarFax vehicle history data
  • Clean, modern interface

Cons:

  • Your data is CarFax's business model
  • Less control over what you track vs. manufacturer-suggested items
  • No offline functionality

Best for: People who don't mind data sharing in exchange for a free app with recall notifications and VIN-based service recommendations.

Road Trip (iOS Only)

Price: $2.99 one-time | iOS only

Road Trip has been in the App Store for over 15 years and has a loyal following. It's particularly strong on fuel economy tracking and has an unusually detailed statistical engine for analyzing driving patterns and costs. Service log features are available but secondary to the fuel tracking focus.

Pros:

  • One-time purchase, reasonable price
  • Exceptional fuel economy statistics and analysis
  • Long track record with consistent updates
  • iCloud sync without requiring an account

Cons:

  • iOS only — no Android support
  • Service log is not the primary focus
  • Interface is dated

Best for: iOS users who prioritize fuel economy tracking and want a one-time purchase without a subscription.

Which App Should You Choose?

The right app depends on what you're trying to accomplish:

  • You want clean, fast service logging with no subscription: RevLog or Road Trip (iOS only)
  • You want comprehensive cost analysis and don't mind a subscription: Drivvo
  • You're primarily interested in fuel economy benchmarking: Fuelly
  • You want free and don't mind your data being used: CarFax Car Care

The Bottom Line on Subscriptions

A $2.99/month subscription for a car maintenance app sounds trivial. Over three years of car ownership, that's $107. Over five years, $178. For an app you'll use to log maybe 20–30 service events per year. That's a poor value proposition compared to a one-time purchase — especially when the core feature set (log a service, get a reminder) doesn't require ongoing server costs that justify recurring revenue.

The best car maintenance apps are the ones you'll actually use consistently. For most people, that means something fast, clean, and cheap enough that you don't resent paying for it every month.
