What you can do in WrenchLog on the web
A real garage
Every vehicle in the driveway with year, make, model, nickname and a live odometer you bump whenever you check it — the reading the whole engine counts against.
Dual miles/months interval engine
Define a service by miles, by months or both; WrenchLog counts forward from your last matching job and the current odometer, and whichever rule lands first wins — Overdue inside the line, Due soon within 500 miles or 30 days.
Jobs with real parts lines
Date, odometer, category, notes for the torque specs you always look up, and itemised parts with brand, part number, quantity and price — so next time the shopping list is already written.
Next-due board across the whole garage
One list sorted by urgency, mixing every vehicle, plus a per-vehicle board and the intervals still waiting on their first matching job.
Costs, cost per mile and DIY savings
Parts spend by category, spend per month over a year, per-vehicle totals, cost per mile from your earliest logged job to today, and the tally of what you saved against the shop quotes you entered.
Export-ready history
Download the whole garage — or one vehicle — as a CSV with a row per parts line: documented owner maintenance that is worth real money at sale time.
