The record of the work you did yourself. Every log app tracks oil changes. Knucklelog vets the proof. Snap the receipt and the record fills itself in — vendor, date, total, part numbers — then gets checked against your odometer history and locked into a ledger a stranger can trust. LOG IT IN SIX TAPS Pick the vehicle, tap the job, snap the receipt. Date and mileage fill themselves in. No receipt? Log it anyway — your word, on the record. THE LEDGER KEEPS SCORE Every vehicle carries its full service history: verified jobs, flagged gaps, documented spend, odometer timeline. Nothing slips, nothing fades. DUE MEANS DUE Set intervals once. Knucklelog watches the calendar and the odometer, and reminds you before the job is late — and nags politely once it is. THE BUYER REPORT When it's time to sell, export the whole verified history as a clean, shareable report. DIY history usually hurts resale — a vetted record flips that.
