Modbook is the logbook your build deserves. Every mod, every service, every dollar — one clean, dark timeline per car. BUILT FOR BUILDERS • Log mods by section — wheels, suspension, exterior, interior, electronics — with price, vendor, install date, and photos • Wishlist → ordered → installed: track parts from dream to done • Up to 50 photos on every car and every part — add a whole shoot at once and pick the one that leads the card • See exactly what your build cost: totals per car and per section, with planned spending kept separate SERVICE BOOK THAT REMINDS YOU • Maintenance records with parts and fluids line items • Reminders that actually fire — every N km or N months, whichever comes first • Update your odometer and due services notify you instantly EVERY MILE, CHARTED • Put the mileage on any entry — a mod, a service, an expense, a run • The odometer chart shows the last 30 days, your average month, and everything tracked WHAT THE CAR REALLY COSTS • Purchase, loan and lease payments, insurance, fuel and charging, washes, subscriptions, fees and fines • Running costs stay separate from what you spent on the build PROVE THE NUMBERS • Dyno runs (power, torque, boost) and Dragy times (0–100, 100–200, ¼ mile) BRING YOUR OLD NOTES • Copy the built-in AI prompt, paste years of messy notes into any chatbot, and import the CSV it gives back • Import the same file twice and nothing doubles up • Export any car to CSV whenever you want — your data is never locked in EV-FRIENDLY • Petrol, diesel, hybrid, or electric — Modbook adapts. EVs get battery & charging service tracking and never see an oil change.
