BuiltNotBought

Built Not Bought is the maintenance logbook for the things you wrench on yourself. Whether you're keeping a daily driver tidy, building out an overland rig, or restoring a project, your build's history lives here — not on the back of a receipt that got soaked in oil six months ago. What you can do: • Log every job with title, date, mileage, category, notes, cost, part model, quantity, where you bought it, and who turned the wrench. • Track multiple vehicles — each with its own photo, profile, and history. • Use the eleven built-in categories (oil change, brakes, tires, suspension, electrical, drivetrain, fluids, filters, armor, wheels, other) or create your own with a custom icon and color. • Browse by date, mileage, or cost. Search anything. Records group by month so you can see how each year of ownership shook out. • A Summary tab with totals, an interactive donut of where your money went by category, and a 1M / 6M / 1Y / All time-range filter. • Export to CSV any time — your data, your file. • Sync across iPhone and iPad via iCloud. No accounts, no servers, no ads, no analytics. If you enjoy the app, there's a tip jar in About. No nags, no paywalls — pay once for the app, keep it forever.
