// The problem

Your build deserves better than a spreadsheet.

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.

Parts log

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.
