About Knuckle Log
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. YOURS, OFFLINE, PORTABLE Works in the garage with no signal — records queue and sync when you're back. Export a complete JSON snapshot anytime. Delete your account and all its data in-app, no email required. PLANS Free: 1 vehicle, on-device receipt OCR, the full ledger, torque specs, and fuel log. Basic ($24.99/yr): 2 vehicles, AI receipt scans (10/mo), buyer reports included, cloud sync. Premium ($49.99/yr): 10 vehicles, AI scans (25/mo) — room for the project cars. Or unlock a one-time Buyer Report for a single vehicle ($35.99). Subscriptions renew yearly until canceled in Settings. Terms: https://knucklelog.com/terms · Privacy: https://knucklelog.com/privacy
What’s new
Version 1.1 · Updated August 11, 2026
Receipts now attach to planned jobs — buy the part weeks before the wrench turns, and the paper trail starts with the purchase, not the finished job. Finishing planned work opens a real log: odometer, labor, notes, photos. No more silent placeholder records. Records are editable for 24 hours after logging — fix a typo without deleting the whole entry and starting over. Minor bug fixes.
