The First Mid-Cycle Update Brings International Support and Critical Refinements to Your Vehicle Maintenance Platform
When we launched Rennch, our mission was clear: Create the finest, comprehensive vehicle maintenance platform for enthusiasts who understand that documentation adds value. And the response has been overwhelmingly positive, with users requesting to further expand the app’s extensive capabilities, especially from international users.
Today, we’re proud to release Rennch v1.10, a mid-cycle update that expands our reach globally while fulfilling the promise to continue adding value to our audiance and refining the precision tools serious car owners demand.
What’s New in v1.10
International Localization Support
Car enthusiasm knows no borders. With v1.10, Rennch initiates support for multiple languages and regional preferences, bringing our platform to enthusiasts worldwide:
- French — Basic interface and core function translations
- German — Basic interface and core function translations
- Italian — Basic interface and core function translations
- Spanish — Basic interface and core function translations
Regional settings now include configurable units (metric/imperial), currency display, and date formats. More comprehensive language support is planned for Q2 2026, expanding translations to all features and documentation.
Streamlined Code Redemption via App Store
We’ve migrated promotional code redemption to the App Store’s native infrastructure. Club members and promotional recipients can now redeem codes seamlessly through Apple’s familiar interface—no separate forms, no additional steps.
Resolved Engine Edit Restrictions
A bug that prevented users from editing engine specifications on existing vehicles has been resolved. Whether you’ve swapped an engine, corrected a VIN decode error, or simply need to update displacement or configuration details, those fields are now fully editable.
New Tire & Wheel Size Fields
Vehicle details now include dedicated fields for tire and wheel specifications. Track factory sizes, document upgraded wheel packages, and ensure replacement parts match your exact setup. This information integrates directly into service reports and parts recommendations.
The Complete Platform: Core Features That Set Rennch Apart
For those discovering Rennch for the first time, v1.10 delivers the full suite of capabilities that make this the definitive maintenance platform for serious enthusiasts.
The Value Proposition: Documented vehicles routinely sell for 10-20% more than undocumented equivalents. Rennch transforms paper records, shoeboxes of receipts, and faded service logs into a permanent, professional digital archive.
Comprehensive Service History Tracking
Every repair, modification, and routine service is captured with date, mileage, cost, parts used, technician notes, and supporting photos or receipts. Whether you did it yourself or had it done professionally, every event is timestamped, searchable, and permanently attached to that vehicle’s record.
Intelligent Document Scanning & Import
Rennch’s built-in document scanner uses Apple’s VisionKit OCR engine to read and extract data directly from physical service records, mechanic invoices, and Carfax Vehicle History Reports. Detected VIN numbers are verified automatically. Extracted service events populate the vehicle’s history with a single review step—eliminating manual data entry for years of prior records.
VIN-Verified Specifications & Schedules
Rennch connects to the NHTSA vPIC database to decode any vehicle’s VIN, importing factory specifications including engine, drivetrain, trim, and manufacturer-recommended service intervals. This ensures maintenance schedules are accurate for your specific vehicle—not a generic model year estimate—and surfaces recall notices relevant to your VIN.
Professional PDF Service Reports
Generate professional PDF Service History Reports on demand—formatted for pre-sale disclosure, insurance documentation, or personal records. Reports include vehicle summary, complete service timeline, mileage progression, cost analysis, and attached photos. Save, print, or share directly from the app.
Secure iCloud Synchronization
All vehicle data—service history, Glovebox documents, inventory, parts, photos, and reports—syncs automatically across iPhone, iPad, and Mac via Apple’s CloudKit infrastructure. Data is encrypted in transit and at rest. Rennch works fully offline and syncs automatically when connectivity is restored.
🔩 Parts & Inventory Management
The Inventory module tracks oils, filters, fluids, brake pads, and any other consumables stored in your garage. Each item links to the vehicle and service type it supports. Reorder thresholds trigger shopping list alerts when stock runs low. The Parts module surfaces manufacturer-recommended products for each VIN-verified vehicle—with direct Amazon ordering links.
Glovebox Document Vault
A secure digital document vault integrated directly into each vehicle’s profile. Scan or upload insurance cards, registration, title, emissions test results, safety inspection certificates, warranty documents, service contracts, owner’s manuals, recall notices, purchase agreements, window stickers, and 24 other document types. Documents are categorized, searchable via OCR, and tracked for expiration—with color-coded alerts as renewal dates approach.
Maintenance Scheduling & Reminders
Upcoming service events—oil changes, inspections, tire rotations, and custom intervals—export directly to Apple Reminders or Apple Calendar with a single tap. Reminders include vehicle name, service type, and due mileage or date.
Intelligent Cost Tracking
Every service entry captures cost data—parts, labor, or total spend—associated with that specific vehicle. The Reports module aggregates this into lifetime maintenance cost summaries, cost-per-mile analysis, and service category breakdowns.
No Subscriptions. No Ads. No Data Farming.
Rennch operates on a fundamentally different model than competitors who treat your data as their product and your wallet as a recurring revenue stream.

From the Developer
“I’ve always tracked maintenance in a written log and on a spreadsheet, complete with part numbers and photos. As the years passed, both my paper records and spreadsheets became cumbersome. I was surprised that there weren’t any apps on the market for the true enthusiasts who want to document every maintenance cycle, repair, or upgrade to prove the provenance of their beloved car.”
Rennch is developed by Chez Mer Studios—founded by a Porsche racer and automotive enthusiast who lives this problem every day. This is purpose-built software by people who understand that documentation is provenance, and provenance is value.
