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), Dragy times (0–100, 100–200, ¼ mile) and lap times by track
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.
YOURS, ON YOUR PHONE
• No account, no ads, no trackers — your garage stays on your phone
• Android's own backup covers your records, and moving straight to a new phone brings the photos too
• Deleted something by mistake? Undo it on the spot, or restore it from the Archive for up to 30 days
• A short video guide on every screen — tap ? to see how it works
• Dark, focused design that belongs in a garage
One timeline. Every wrench turn. Modbook.
Recent changes:
Motorcycles: tap + in the Garage and pick Motorcycle. A bike gets Chain and Valve clearance reminders by distance, Bodywork and Ergonomics in Mods, and its own guide page.
Any reminder distance: tap the distance to type any figure, like 500 km for a chain, or step it with − and +.
Edit from the Garage: long-press a car or motorcycle to edit it, not only to delete it.
