The world's first all-in-one maintenance app for every vehicle you own — aircraft, cars, boats, motorcycles, fleets, and heavy equipment.
If you want to be the most organized you can possibly be when it comes to tracking and performing maintenance, look no further. See every vehicle's status at a glance, keep every receipt and record in one place, and let a detailed reminder system alert you before anything comes due — or overdue. The future has arrived.
An airplane or two, some motorcycles, a boat, a couple of family cars. Notepads, whiteboards, and filing cabinets only tell you a maintenance item is overdue after you've missed it. See every vehicle you own in one organized spot — status at a glance, receipts and history in one place, and reminders before anything comes due.
Take care of several aircraft? Your customers pay a low monthly subscription, and you see every customer aircraft in one place — customized alerts, the full AD library, annual and 100-hour inspection checklists, and reminders when a customer's maintenance, ADs, 100-hours, or ELT checks are coming due.
Do the research yourself, then hand it off. Search the full AD library against your airframe, engine, prop, and appliances, build an easy-to-read compliance sheet, and log the service and preventative maintenance you perform along the way — oil changes, plugs, filters, all of it. When inspection time comes, grant your A&P/IA access to the app in a few clicks: they see your compliance sheet, service history, logbooks, and receipts digitally, verify your work, and sign off — instead of billing hours to dig through paperwork. You save on the annual, and you know your aircraft better than anyone.
Timing belt services, oil changes, tire date codes, registration and insurance expirations — all tracked. Smart warranty alerts warn you before anything expires, and if your cars sit in a corporation, HM reminds you before fees and taxes are due so you don't incur costly penalties.
Plumbing, construction, HVAC, rental cars — if you run a fleet, HM has you covered. Maintenance, registration, insurance, oil changes, and services, with every record and document stored per vehicle. Need an old service record? Click the vehicle and it's there — copy, export, email, or print. A built-in expense calculator generates P&L statements so you know what your fleet costs to run.
Track all of your heavy equipment — what was done and when it was performed. No more guesswork, notepads, or filing cabinets. Click the vehicle, pull up its history, build custom maintenance tabs for specialized items, and keep every receipt in one place.
Multiple aircraft, multiple pilots, hours stacking up fast. The built-in flight logbook shows who flew each plane and for how long, revenue flights vs non-revenue, and the flight timer keeps 100-hour inspections and hourly components current automatically. Put revenue hours against expenses and see if each aircraft pencils to keep flying.
One boat or a rental fleet, HM tracks it the same way it tracks a plane. Engine services, registration and insurance expirations, seasonal maintenance, and every receipt stored per vessel. Partnerships see who used the boat and split expenses, and rental operations get P&L statements that show what the water is really costing.
The same treatment for everything on wheels. Oil changes, timing belts, tire date codes, registration and insurance reminders, and warranty alerts before they expire. Share a car with partners and split the costs, or run a rental fleet with per-vehicle records, expense tracking, and P&L statements.
We've thought of everything — track it, document it, and get reminded before it's due. And there are more features coming soon.
The complete FAA Airworthiness Directives library lives inside the app and refreshes every two weeks. Search by airframe, engine, prop, AD number, or component, and build compliance sheets that are easy to understand.
Let Edan, the built-in AI assistant, help you with the following: AD interpretation, building a vehicle profile, managing your fleet and setting critical reminders, scheduling service, and more.
Detailed tracking of any and all maintenance items for every vehicle. Don't see it listed? Create it — customizable maintenance fields let you track a home generator or a gas-powered pressure washer.
Digitize your aircraft maintenance logbooks as a backup. If a logbook is ever lost or damaged, your maintenance history — and your aircraft's value — stays protected.
Keep receipts and anything important related to your vehicle stored as PDFs. Find any record in seconds — then copy, export, email, or print it.
Track every dollar and generate P&L statements. Know what your vehicle or your fleet costs to operate on a monthly or yearly basis.
Reminders for loan payments due, plus corporation tracking for the filings and taxes tied to the vehicles you hold in that corp — before late fees pile up.
Stop overbuying parts you forgot you had on the shelf or misplaced, and don't get caught reaching for something you're out of. Assign parts to specific vehicles, keep track of inventory, and note exactly where each part is stored. Custom alerts let you know when you're running low and when to reorder — and you can create custom categories.
Maintenance, inspections, warranties, registrations, parts — customizable alerts warn you before anything comes due or expires, not after.
Generate invoices and work orders right out of the app — built for independent mechanics and shops who want to bill straight from the maintenance record.
Start the flight timer and everything you track hourly updates itself. Search the full AD library, build compliance sheets, and get alerted before inspections and recurring ADs come due.
Get organized and have it all at your fingertips — from the shop generator, the farm tractor, and the tug that pulls your equipment to the golf cart in your hangar. High Maintenance gives every user the highest professional shop organization available.
Don't see a vehicle listed? No problem — our custom vehicle profile lets you create one.
See pricingHigh Maintenance was designed by an A&P/IA mechanic who currently cares for many aircraft — and who has spent his career simultaneously working on aircraft of all kinds, boats, dirt bikes, and exotic cars, specializing in Ferrari, Lamborghini, Porsche, and Maserati. He's also a pilot who regularly flies WW2 warbirds, small aircraft, and a corporate jet, and he remains hands-on in exotic car and marine repair today.
That background is why this app is so advanced and forward-thinking. It carries aviation's standard of safety, engineering, and organization into every machine you own — designed by someone who lives maintenance every single day, across the hangar, the shop, and the water.
High Maintenance was made because nothing like it exists. In today's modern age, no one should be storing all of their vehicles in different places, with different spreadsheets and notepads. Our competitors also fall short on key features needed in today's modern world. This app was made to do everything they do — and all of the things they don't.

No mockups — these are real screenshots from High Maintenance, with a look at what each page does for you.
A Baron, a Bonanza, a Cessna, a seaplane, an excavator, a Ford F-350, a Ferrari, and a Canam side-by-side — this is a real fleet. Each card answers the only question that matters before you walk out the door: is it ready, or is something overdue?
Filter the fleet by category — aircraft, rotorcraft, cars, trucks, motorcycles, RVs, boats, off-road, heavy equipment, even generators — with live counts for each. And if you own something we didn't think of, add a custom category and track it anyway.
This is a real aircraft page — a 1966 Beechcraft Baron BE-55C. Its status sits right next to the tail number, so you know it's grounded before you drive to the airport. Airframe, engine, and prop times are laid out at a single glance, and they update automatically every time you log a flight.
Editing an aircraft walks you through a section for everything that matters — general information, ARROW documents and insurance, engines, props, floats and parachutes, fuel tracking, oil and filter changes, and annual/100-hour inspections. Anything expired wears a red badge you can't miss.
Every dollar, categorized: insurance, hangar rent, maintenance, corporation fees, hourly operating cost. The breakdown chart shows where the money actually goes, the expense log keeps the receipts, and the year's running total is always current.
