EngineHoursLog records engine hours, parts, and maintenance for the equipment people care about — boats, RVs, tractors, generators. Text-only. Offline-first. Free export forever. Built to still be useful in 2036 when you sell the boat to someone's kid who wasn't born yet.
You don't buy a logbook because you love logging. You buy one against a future regret — the one you've already had, maybe twice.
Two identical boats on the broker's listing. Same year, same engine, same price. One has a shoebox. The other has a clean PDF: every hour, every part, every receipt, signed off by the mechanic. Which sells first? Which sells for more?
Saturday morning at the marina. Is the fuel filter due, or did you do it last fall? The guy who worked on it moved to Florida. You either skip it and hope, or pay for it twice. Both are bad.
"When was the impeller last replaced?" — "Uh, two years ago? Maybe three?" He shrugs, charges you for one anyway, because he's not going to trust your memory with a $10,000 engine.
A single tablet demo, walked through in plain English. No dashboards of graphs you'll never look at. No notifications begging for attention.
Pick a category — boat, RV, tractor, generator. The template knows about the impeller, zincs, fuel filter, oil, coolant, and belt. You don't start from a blank spreadsheet.
Works offline. No signal at the slip, in the hangar, at the back pasture, or behind the cabin. Syncs later, when you're near a router again.
Vendor, part number, cost, hours-at-install, who did it. "This impeller averages 700 hours between failures, last one from West Marine for $47." A photo can't tell you that.
A boat that sits all winter doesn't get spammed with "overdue." The rule is every 200 hours, or every 12 months — whichever comes first. It waits.
Read-only or read-write, your choice. Their work lands in your log, attributed. When the job's done, access goes away. No passwords exchanged.
One button. The buyer gets every hour, every part, every receipt link, back to day one. The log doesn't get reset. That continuity is worth money at the dock.
Your data is yours. Export formats are documented and versioned. If we disappear tomorrow, you still have every record in a format anyone can read.
You won't use this at a laptop. You'll use it one-handed, in gloves, on a phone, in sunlight so bright the screen is barely legible — or in a dim engine bay at dusk. So we built two themes, both real: Sunlight mode is pure black on pure white, heavy strokes, thumb-sized buttons. Engine-bay mode is amber on near-black — night-vision-safe, no blue light to kill your dark adaptation.
Haptic confirmation on every tap. Persistent "saved locally" messages, not disappearing toasts. The word "OVERDUE" carries the meaning, not the color — so it works for the 8% of men who are color-blind, and for everyone at noon. See the full theme mockups →
For a tool you have to trust for a decade, restraint builds more credibility than ambition. Here's what we deliberately won't do.
Aviation has legal logbook requirements. We don't touch that, and we never will. If you're a pilot, you need an FAA-compliant tool — not this one.
Commercial trucking, inspected vessels, passengers-for-hire. Regulated categories need compliance software. That's not us.
Reminders are suggestions based on manufacturer intervals and your rules. They're not instructions, not recommendations, not safety advice.
No image or receipt storage on our servers. You paste a link to where it already lives — your email, your Drive, your Dropbox. Your data, your storage, your control.
No ads. No data sale. No free tier funded by surveillance. You pay a small subscription, or you use a limited free tier — those are the only two business models we will ever have.
This is a ten-year tool. We're pricing it to be sustainable, not to grow fast. If we ever shut down, the export tool stays online for 12 months. You will not lose your log.
A generous free tier you can live on forever, and paid tiers that scale with how much equipment you actually have. Annual or monthly — whichever fits how you think about money.
That's the real question for a tool you use five times a year. Feature lists don't answer it. These do. They're binding — published in our Terms of Service, unchangeable without twelve months' public notice.
Full export in open formats — JSON, CSV, PDF — free and unrestricted, for every user, at any time, including after cancellation. Format specifications are public and versioned.
If we ever cease operations, the export tool stays online for a minimum of twelve months after the announcement, and the export format specifications are published publicly. You will not lose your log because we went out of business.
The product is funded by subscription revenue. It will not display ads, sell user data, or introduce an ad-supported tier. Those words are in our ToS.
We will never quietly add aviation, DOT, USCG, or life-safety categories. Any change to this commitment requires a published explanation and twelve months' notice to existing users.
Sync across devices, mechanic sharing, ownership transfer, email reminders. We'll email you once when it's ready. No drip campaigns, no newsletter, no marketing mail.
We ship in English. Real translation is a human job — we will hire native-speaker pros, not machine-translate. Tell us which language should come next, and we'll prioritize demand.
One engine. Free forever if that's all you need. Account-backed so a phone upgrade does not erase your log. Upgrade when you add a second, want active sync, or put the boat on the market. Not before.
