If you’re a serious car enthusiast—especially if you own a Porsche, BMW, or any collectible vehicle—you know that meticulous maintenance records aren’t just good practice. They’re essential for preserving your vehicle’s value and provenance. That’s where Rennch comes in.
Why Digital Service Records Matter
Traditional paper service records get lost, fade, or become disorganized over time. When it’s time to sell your vehicle, an incomplete maintenance history can cost you thousands of dollars in resale value. Buyers want proof of regular maintenance, documented repairs, and a complete ownership timeline.
Rennch transforms your iPhone, iPad, and Mac into a comprehensive digital service record system that travels with you—and your vehicle—everywhere.
Core Features That Set Rennch Apart
Complete Service History Documentation
Log every oil change, brake service, tire rotation, and major repair with detailed notes. Attach photos of receipts, work orders, and before-and-after shots. Each service record includes:
- Date and mileage
- Service description and parts used
- Cost tracking
- Photo documentation
- Service provider information
Professional PDF Reports
Generate stunning, professional-quality maintenance reports perfect for insurance claims, resale documentation, or your personal records. These reports include your complete service history, photos, and costs—all formatted beautifully and ready to print or share.
VIN-Specific Maintenance Schedules
Enter your vehicle’s VIN, and Rennch automatically retrieves manufacturer-recommended maintenance schedules from the NHTSA database. No more guessing when your next service is due—the app tells you exactly what needs attention and when.
