MotorMia
MotorMia was built as an AI-powered modification and tuning planner, parts finder and performance analyst.
The app at its core continues to evolve, and recently launched its new glovebox feature for tracking logs and documentation for your vehicle.
The “glovebox” feature works for storing important vehicle documentation and records. Users can log maintenance activities like oil changes, track installed modifications, and maintain a chronological history of their vehicle’s evolution. The app provides a way to catalog parts and modifications with photos, creating a visual timeline of your build progress.
Users can visually track modifications with photos and keep all documentation organized within the app. It also integrates with parts retailers to assist with aftermarket part discovery.
CARFAX Car Care
CARFAX leverages its massive database to provide comprehensive maintenance tracking. Enter your VIN and the app pulls your vehicle’s complete service history, then automatically schedules future maintenance based on manufacturer recommendations.
The standout feature is automatic service record updates from participating shops. Get your oil changed at a CARFAX partner location and it appears in your history without any input. Recall notifications arrive instantly, and the app tracks multiple vehicles easily.
Downsides include limited customization for modified vehicles and reliance on partner shops for automatic updates. DIY mechanics need to manually enter service records, reducing the automation advantage.
Drivvo
Drivvo takes a comprehensive approach to vehicle management, tracking everything from fuel consumption to insurance payments. Its strength lies in detailed analytics that help identify cost patterns and optimize vehicle expenses.
The app shines for multi-vehicle households or small business fleets. Expense reports export easily for tax purposes, and the fuel tracking reveals real-world MPG trends. Service reminders adapt based on mileage or time intervals.
The interface feels dated compared to competitors, and the free version limits you to one vehicle. Premium pricing gets expensive for larger fleets compared to dedicated fleet management solutions.
Simply Auto
Simply Auto focuses on doing basic maintenance tracking exceptionally well. The clean interface makes logging services quick, while cloud backup ensures your records survive phone changes.
Multiple vehicle support comes standard, making it perfect for car enthusiasts with several projects. The app handles different maintenance schedules per vehicle and sends reminders based on mileage or date intervals. Export options include CSV and PDF formats for easy sharing.
Limited diagnostic integration and no parts shopping features keep it focused but less comprehensive than alternatives. The app works best for users who want straightforward tracking without extra bells and whistles.
AUTOsist
AUTOsist targets both personal and commercial users with robust document management features. Store photos of receipts, warranty documents, and registration info alongside maintenance records.
Fleet features include driver assignment, fuel card integration, and comprehensive reporting. The web dashboard provides deeper analytics than the mobile app. GPS tracking helps businesses monitor vehicle usage and optimize routes.
Personal users might find the business features overwhelming, and the subscription model gets pricey for individual vehicles. The interface prioritizes function over form.
myCARFAX
myCARFAX simplifies setup with license plate lookup, eliminating VIN hunting. The app focuses on essential maintenance tracking with a consumer-friendly interface that anyone can navigate.
Service history from CARFAX’s network appears automatically, creating comprehensive records without manual entry. The app sends timely reminders for upcoming maintenance and notifies you about recalls affecting your specific vehicle.
Features remain basic compared to enthusiast-focused apps. No modification tracking, limited customization options, and minimal expense tracking keep it simple but less versatile.
Fuelly
Fuelly started as fuel tracking but evolved into basic maintenance logging. The community aspect lets you compare your vehicle’s efficiency against identical models, revealing potential issues through MPG drops.
The massive user database provides real-world fuel economy data for nearly every vehicle. Maintenance reminders tie to fuel-ups, making it easy to track oil changes every X gallons. The web interface offers better analytics than the mobile app.
Maintenance features feel secondary to fuel tracking. No parts integration, limited service categories, and basic reminder options make it best suited as a companion app rather than primary maintenance tracker.
Torque Pro
Torque Pro transforms your phone into a professional diagnostic scanner when paired with an OBD2 adapter. Real-time engine data, fault code reading, and performance monitoring put dealership-level diagnostics in your pocket.
Custom dashboards display any parameter your car reports. Track everything from boost pressure to transmission temperature. The app logs data for later analysis and can email diagnostic reports. Third-party plugins expand functionality further.
The learning curve intimidates casual users, and you need a compatible OBD2 adapter. Focus on diagnostics means basic maintenance tracking takes a backseat to technical features.
FIXD
FIXD simplifies automotive diagnostics for everyday drivers. The app translates cryptic engine codes into plain English explanations with severity ratings and repair cost estimates.
The proprietary FIXD sensor continuously monitors your vehicle, sending alerts about potential issues before they become expensive problems. Maintenance reminders adapt based on your driving habits. Multiple family vehicles connect to one account.
The app requires FIXD’s specific sensor, adding upfront cost. Repair estimates vary by location and might not reflect your area’s pricing. Advanced users find the diagnostics too simplified.
