About Wrenzo
Wrenzo is a vehicle ownership workspace for keeping symptoms, maintenance, repairs, reminders, attachments, imports, and records in one organized place. It helps turn confusing vehicle problems into clearer next steps while preserving the history that makes future decisions easier.
It is not here to replace a mechanic. It is here to help you describe what happened, remember what was done, and know what questions to ask when you inspect, repair, or bring a vehicle to a shop.
Built For Every Screen
Wrenzo is designed to feel natural on desktop and mobile, whether you are organizing records at home or checking details from your phone near the vehicle.
Turn symptoms into next steps
Start with what the vehicle is doing, not a guess at what part failed. Wrenzo turns symptoms into likely causes, inspection ideas, DIY research links, shop-ready talking points, and relevant NHTSA recall or complaint findings when they are available.

Scan your whole garage
Your Garage keeps every vehicle in one clean, scannable place. Review ownership status, compare vehicle cards, import existing maintenance records, open the logbook, or jump back into the vehicle that needs more work.

One vehicle, all the context
Each vehicle gets its own workspace for history, fuel or charge logs, service intervals, reminders, and tools. It is built for the everyday stuff too: adding maintenance, checking what is due, preparing a quick-log QR code, or sharing records when needed.

Follow problems over time
When there is an issue you want to track, Wrenzo can keep the related follow-ups together. Issue threads connect the original issue with reminders, repair entries, notes, status updates, and the final resolution. Health snapshots add a quick condition read for each vehicle so open issues, overdue items, and setup gaps are easier to spot.

Plan builds without losing the trail
Project threads are for longer-running work that is more than a single repair entry: builds, restorations, upgrades, swaps, or major refreshes. Track the goal, budget, target date, checklist, parts, attachments, time spent, and project activity so the plan and the record stay together.

Review everything in your garage
The Logbook brings the whole garage together. Filter by vehicle, review history, inspect reports, manage reminders and intervals, track fuel or charge logs, and understand spend without bouncing between pages.

Track cost and efficiency over time
Fuel and charge logs help turn everyday fill-ups and charging sessions into useful ownership context. Track odometer, cost, gallons, liters, kWh, station or charger notes, receipts, and whether a fill was full or partial. Wrenzo can show efficiency and price trends, flag a meaningful drop in recent efficiency, turn that alert into a trackable issue, and export logs when you want the data outside the app.

Make records easy to use later
Good records are easier to trust later. Wrenzo keeps imports, attachments, exports, sharing, transfers, and reminder emails close to the vehicle history so the logbook stays useful over time.
