// The problem
Most people track their builds in notes apps, spreadsheets, or Instagram captions. Months later they can't remember what clutch they ran, what it cost, or when they installed it. PitLog fixes that — without the overhead of apps that weren't built for this.
// 01
Part name, part number, vendor, cost, date. Every install recorded with the detail you'll actually need six months from now when you're ordering that part again.
// Build entries
47 total// 02
Running total auto-calculated with a breakdown by category — engine, suspension, exterior, brakes, and more. Know exactly how deep you're in at any moment.

// 03
Attach a photo to any entry. Watch the whole build come together in chronological order. The before/after documentation you'll want to have when the build is done.
