Your build deserves better than scattered notes, random receipts, and half-remembered part numbers. Build Bible is the go-to app for car enthusiasts who take their builds seriously. Whether you're wrenching on a weekend project, building a track car, or restoring a classic, Build Bible keeps your entire build organized in one place. Log every session. Use voice or text to capture what you worked on, what you installed, and what still needs doing — right there in the garage while it's fresh. Track every part. Store part numbers, brands, sources, and costs so you always know what's on the car, what's on order, and what's on the wish list. Own your budget. Set a build budget, track spending by category, and always know where your money is going before it's gone. Multiple builds, zero chaos. Running more than one project? Switch between vehicles instantly and keep each build completely separate. Stop losing information between text threads, Notes apps, and old receipts. Build Bible is the one place your build lives.
