Built for what you drive

Not just cars. Everything with an engine, or a trailer hitch.

Most maintenance apps stop at the car in your driveway. Wrench Wise™ starts every type of vehicle with a schedule built for it, counted in miles, engine hours or months.

Tracks miles or km

Your car’s maintenance schedule, without the guesswork.

Add your car, truck or SUV and get a starter maintenance schedule in seconds, then log each service as you do it. With Pro, import your owner’s manual or, for supported makes, the manufacturer’s factory schedule when you want the exact intervals.

  • VIN decode & camera scan. Scan or type the VIN to fill in year, make, model and engine.
  • Normal or severe service. Importing your owner’s manual? Choose normal or severe/heavy-duty intervals, whichever matches how you drive. Pro
  • Oil-life monitor. Enter the oil-life percentage from your dash and Wrench Wise™ tracks the next change from it.
  • Recalls (US). Checks NHTSA for open safety recalls on the vehicle and its tires. Pro

Two cars under a carport at a family home

Families

The family mechanic’s garage.

One person usually keeps every car running: yours, your partner’s, the teen driver’s, maybe a parent’s. See what’s due across all of them, and with Pro share the garage with your household so everyone can log fuel and service and leave notes, and you can see who did what.

  • Up to 5 people with Pro
  • Choose who sees which vehicle
  • Read only, or notes and logs

A classic red tractor in a green field

Hobby farms & acreage

Everything with an hour meter, in one place.

The tractor and its implements, the side-by-side, the generator, the trailer and the truck all run on different clocks. Wrench Wise™ keeps each on its own schedule (hours, miles or months) and shows what’s due across the whole place.

  • Tractors and implements by hours
  • ATVs, generators and trailers
  • One What’s Due for everything

A used pickup truck parked by the beach

Buying used

Check it before you buy it.

Add the vehicle you’re looking at and work through the built-in pre-purchase inspection: VIN matches the title, body, undercarriage, engine, test drive, interior, tires, lights, maintenance history and recalls. Scan the VIN to fill in the details. Seller uses Wrench Wise™? Skip adding it yourself and accept their records instead.

  • 10-item pre-purchase inspection
  • VIN scan fills in the details
  • Or accept the seller’s records (Pro)

A home standby generator

Home backup power

Ready before the storm, not after.

A standby or portable generator sits unused until the night you need it. Wrench Wise™ tracks oil and filters by its hour meter, reminds you to load-test it every year and stabilize the fuel every six months, so it starts when the power goes out.

  • Oil, air filter and plugs by hours
  • Yearly load test
  • Fuel stabilization every 6 months
Generator maintenance →

Also great for classic and collector cars (a custom storage checklist and a documented history that supports their value) and anyone who uses a shop: log each visit, scan the invoice with Pro, and keep the records ready for a warranty claim.

Smarter than a mileage reminder

A real maintenance plan, not a list of reminders.

Wrench Wise™ groups what’s due into checkups the way a service department does, logs a whole shop visit in one go, and moves every interval forward from the work you actually did.

  • Checkups by mileage, hours or time.
    See everything due at 45,000 miles, at 100 hours or this spring, together.
  • Complete a whole visit at once.
    Select the checkup, enter the shop and total cost once, and every item is logged.
  • You choose how intervals reset.
    Roll forward from each service, keep the original 5k/10k/15k plan, or use a fixed date for registration and inspections.
  • Skip one, keep the rest.
    Skip an item at this checkup only, with a reason; it still appears at future ones.
  • Oil-life monitor aware.
    Enter your dash reading and the next oil change is projected from it, within the manufacturer’s limits.
  • Scan the shop invoice. Pro
    Wrench Wise™ reads the work and matches it to your schedule items for you to review.

Sell it for more

Hand the next owner the proof.

A documented service history is one of the best arguments at sale time. Wrench Wise™ lets a buyer check the history before they commit, then moves the records to them when the deal is done.

  • Share a read-only history link. Pro
    Anyone with the link can see the service history for 30 days, with no account needed. Your name, plate, photos and receipts are never shown, and costs and notes only if you choose. You see when it’s opened.
  • Useful for your mechanic too.
    Send the same link to a shop that wants to know what’s been done.
  • Transfer the records at sale. Pro
    Choose what goes (service history, schedule, parts, tires, costs, notes, photos) and give the buyer a one-time code or QR code. It expires in 14 days.
  • Nothing lost on your side.
    The buyer gets their own copy. Yours is marked sold and kept read-only.

Sharing and transferring need Pro. To accept a transfer, the buyer needs a Wrench Wise™ account and Pro.

Do it yourself, do it right

Checklists and guides for the jobs you do every season.

Winterize the RV, commission the boat, check the bike before a long ride. Wrench Wise™ keeps the steps, the notes and the history, free and offline.

  • Checklists for every season.
    Into storage, out of storage, pre-trip, post-trip, safety, pre-purchase, annual, or your own. RVs, boats, bikes, sleds, tractors and generators come with seasonal templates.
  • Grouped by system.
    An RV’s list splits into coach, generator and chassis, so nothing gets missed.
  • Notes, print and “copy to next year”.
    Keep observations with each list and reuse it next season.
  • Step-by-step guides.
    Write your own with photos on every step and video links, or start from 37 built-in examples that work offline.
  • Linked where you need them.
    Attach a guide to a schedule item or a checklist task and the how-to is one tap away.

Know what it costs

Fuel, service and every other dollar, in one place.

Log a fill-up in seconds and Wrench Wise™ works out the economy, the cost per mile or per hour, and what the whole garage is costing you.

  • Fast fuel logging.
    Enter any two of volume, price and total and the third is filled in. Add the station (or use your location), a discount app, the receipt photo, and whether it was a full fill.
  • Charging and DEF too.
    EVs log charge sessions in kWh; diesels log DEF.
  • Economy you can trust.
    Current and lifetime mpg, km/L or L/100 km, and fuel cost per mile. Boats and generators get operating cost per hour.
  • Total spent, everywhere.
    Garage totals split into maintenance and fuel, a spend view by vehicle, and an all-in cost per mile on each vehicle.

Plan the job

Turn what’s due into a plan, a parts list and a shopping trip.

  • Plans from anywhere.
    Add tasks from the schedule, a seasonal list, a repair, or your own.
  • Parts and estimates per task.
    Parts to buy (mark what you already have), a cost and time estimate, and DIY or shop.

Parts

Never wonder “what part was it?” again.

Wrench Wise™ keeps the part numbers, fluid capacities and substitutes for each vehicle, knows which services use each part, and tells you when one is due.

  • A parts catalog for every vehicle. Pro
    Part number, brand, supplier, price, quantity per service, fluid capacity, reference photos and notes.
  • Substitutes and favourites.
    Keep the cross-references and star the one you actually buy.
  • Linked to the work.
    See which services use each part, when it was last changed, and its service history.
  • Remaining life.
    Parts running out of life show up in What’s Due and under Needs attention, e.g. “Overdue by 500 mi”.
  • Straight into the next job.
    Add a part to the buy list, pick it while planning, or (on a boat) add spares to the inventory.

The parts catalog is Pro. On the free plan you can view it, but not add parts.

Wrench Wise™ app: Every vehicle has a parts catalog (Pro).
Wrench Wise™ app: Your parts, by part or by the service that uses them.
Wrench Wise™ app: Open a part…
Wrench Wise™ app: …for its substitutes, the services that use it, and its history.

Bring your records

Kept it in a spreadsheet? Bring it with you.

Years of service history shouldn’t start over in a new app. Import your spreadsheet, scan the shop invoices, and keep the paperwork with the vehicle.

  • CSV and Excel import.
    Upload a .csv, .xlsx or .xls file. Columns are matched automatically, every row is previewed, and duplicates of records you already have are flagged. Up to 500 records per import, free on phone and tablet (and on the web with Pro).
  • Scan the VIN.
    Point the camera at the VIN barcode to fill in the year, make, model and engine.
  • Documents with the vehicle.
    Keep the registration, insurance card and window sticker as photos or PDFs.
  • Scan shop invoices. Pro
    Snap the invoice and the work, parts and costs are read for you to review.

Why Wrench Wise™

One app instead of three, plus the spreadsheet.

FAQ

Questions, answered

Is Wrench Wise™ free?

Yes. The free version tracks 2 vehicles, or 1 vehicle with up to 3 add-ons such as boat engines, an RV generator or tractor implements. It includes starter schedules, What’s Due, reminders and unlimited service logs. Pro adds unlimited vehicles, sync and backup, manual import, recalls, reports and household sharing, and comes with a 14-day free trial. Pro is $4.99 a month or $29.99 a year in the US, C$6.99 a month or C$39.99 a year in Canada and A$7.99 a month or A$47.99 a year in Australia.

Do I need an account or an internet connection?

Not for the free version. It needs no account, stores everything on your device and works completely offline, so you can log a service at the boat ramp or the campsite. Pro uses an account and works both online and offline: on your phone or tablet you keep working with no signal, and your changes sync to your other devices, with automatic backup, once you’re back online. The Pro web app needs a connection.

Which vehicles does it support?

Cars, trucks and SUVs (gas, diesel, electric, hybrid and plug-in hybrid), RVs and motorhomes of every class including travel trailers and fifth wheels, powerboats, sailboats, personal watercraft, motorcycles, ATVs and UTVs, tractors and riding mowers, snowmobiles, trailers and generators. Aircraft support is coming soon.

Where do the maintenance schedules come from?

Every vehicle type starts with a starter schedule built for it, counted in miles, engine hours or months. Pro members can import their own owner’s manual (PDF) and choose normal or severe intervals, or import the factory schedule for supported makes. You review every item before it’s saved, and you can edit any interval.

Can it track engine hours instead of miles?

Yes. Boats, personal watercraft, tractors, ATVs and generators are tracked by their hour meters. A boat or catamaran can have several engines and an onboard generator, each with its own hours and marine schedule, and an RV’s generator runs on its own hour meter while the chassis runs on miles. Aircraft, coming soon, will track the airframe, each engine and each propeller separately.

Can I track solar panels, a wind generator or house batteries?

Not with a built-in template yet. Add your own schedule items to the boat or RV (clean the solar panels, check the charge controller, service the wind generator, test the house batteries) on any interval you choose; on a boat, keep the spares in its inventory. Fuel-burning generators are built in: on boats they get a marine schedule with the raw-water impeller, zincs and heat exchanger.

How does selling a vehicle work?

With Pro, share a read-only history link so a buyer (or your mechanic) can see the service history for 30 days without an account; costs and notes stay hidden unless you include them. When you sell, transfer the records: choose what goes, and give the buyer a one-time code or QR code that expires in 14 days. The buyer needs a Wrench Wise™ account and Pro to accept. They get their own copy, and yours is kept read-only.

Is the aircraft support a compliance tool?

No. Aircraft support, coming soon, will help owners keep track of maintenance on the airframe, engines and propellers, but Wrench Wise™ is not an airworthiness system. It does not track Airworthiness Directives, inspection sign-offs or compliance. Keep your logbooks and required records as you do today.

Where is it available, and does it work in kilometres and litres?

Wrench Wise™ is available in the US, Canada and Australia, with more countries coming. Pick miles or kilometres, quarts, gallons or litres, and °F or °C in settings, and see fuel economy as L/100 km, km/L, US mpg or UK mpg. One thing is US-only today: recall checks use the US NHTSA database. Everything else works the same in every market.

Can my family use it too?

With Pro you can share vehicles with your household, up to 5 people including you. Invite people with a link or QR code, choose which vehicles each person sees, and let them read only or leave notes and log fuel and service. Every entry shows who made it.

Does it check for recalls?

Pro checks the US NHTSA database for open safety recalls on your vehicles and their tires. Recall checks are not available in countries without a supported recall source.

Can I get my data out?

Yes. Free users can export from their device. Pro adds service-history and expense reports as PDF, and lets you transfer a vehicle’s history to its next owner when you sell.

Which devices can I use?

iPhone and iPad, Android phones and tablets, and the web in any modern browser. Phones and tablets each get their own layout. The free app works on one device with no account; Pro adds an account that backs up your garage and keeps it in sync across all your devices, including the web app.

Your next oil change is already on the calendar.
