WrenchLog: Car Maintenance Log

WrenchLog is the private, ad-free vehicle maintenance tracker that keeps your cars healthy and your wallet informed.

No account. No ads. No tracking. Your data stays on your device — period.

▸ VIN DECODER
Enter your 17-digit VIN and WrenchLog auto-fills make, model, and year from the official NHTSA database. No manual entry needed.

▸ SAFETY RECALL ALERTS
WrenchLog checks your vehicle against the NHTSA recall database and alerts you to any open safety recalls. Stay safe without lifting a finger.

▸ TRACK EVERY SERVICE
Log oil changes, tire rotations, brake work, battery replacements, and 20+ preset service types across 6 categories. Record date, mileage, cost, notes, and attach receipt photos to every entry.

▸ FUEL TRACKING & EFFICIENCY
Log every fill-up with fuel type, volume, cost, and station name. WrenchLog calculates your MPG (or L/100km), cost per mile, and tracks efficiency trends over time with interactive charts. Supports Regular, Mid-Grade, Premium, Diesel, E85, and Electric vehicles.

▸ SMART REMINDERS
Never miss another oil change. WrenchLog sends intelligent reminders based on time intervals, mileage thresholds, and your actual driving pace. Each reminder learns how fast you drive and notifies you at the right moment — not too early, not too late.

▸ VEHICLE HEALTH SCORE
See your car's maintenance health at a glance with a 0–100 score. The score weighs critical services (engine, brakes) heavier and updates in real time as you complete services or fall behind.

▸ COST ANALYTICS (Pro)
Donut charts for service-vs-fuel split, category breakdowns, monthly spending trends, yearly cost of ownership, and per-mile cost tracking. Know exactly where your money goes.

▸ PDF EXPORT (Pro)
Generate clean, professional service history reports in PDF format. Perfect for selling your car, insurance claims, or sharing with your mechanic.

▸ CSV EXPORT & IMPORT
Export all your data as CSV files for backup or analysis in a spreadsheet. Import service records from CSV to migrate from other apps or paper logs.

▸ MULTI-VEHICLE GARAGE (Pro)
Manage your entire fleet — cars, trucks, motorcycles, anything with wheels. Each vehicle gets its own dashboard, timeline, health score, and reminders. Compare costs across vehicles with side-by-side charts.

▸ MAINTENANCE TIMELINE
See every service and fill-up on a chronological timeline, grouped by month. A visual history of your car's entire life.

▸ MAINTENANCE CHECKLIST
Create custom to-do lists for each vehicle. Pre-loaded suggestions for common checks like tire pressure, oil level, and brake inspection.

▸ SEASONAL TIPS
Maintenance suggestions based on the current season — winterize in December, check A/C before summer.

▸ MILESTONE BADGES
Earn badges as you build your history — First Service, Dedicated, Road Warrior, Fleet Owner, and more.

▸ CUSTOMIZABLE UNITS
Miles or kilometers. Gallons or liters. MPG or L/100km. WrenchLog speaks your language.

▸ FIVE COLOR THEMES
Default Amber, Ocean Blue, Dark Mono, Forest Green, or Sunset Rose. Pick what looks right to you.

▸ PRIVACY FIRST
WrenchLog collects zero personal data. No account signup. No analytics SDKs. No third-party tracking. No ads — ever. Your vehicle data never leaves your device. We don't sell your information to data brokers, insurance companies, or anyone else.
