Hourbook
Every machine in the barn, serviced by the hour meter — not by guesswork
Log the meter when you climb off, and Hourbook learns each machine's hours-per-week rate to turn “due at 400 hrs” into a real calendar date. Due Board, parts counter card and dated service history. Free, offline, no install.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in Hourbook on the web
The Barn
Every hour-metered machine on one screen — tractor, zero-turn, ATV/UTV, skid steer, generator — each card showing current hours, its usage rate, and what's due next.
Hour ledger with usage rate
Log the meter reading and a note; Hourbook fits a hours-per-week rate from the last 90 days of readings and charts the meter over time.
Due Board across the whole barn
Every service interval sorted soonest-first with hours remaining, the projected calendar date, and OVERDUE / DUE SOON / OK status.
Intervals the way manuals write them
Every N hours, every N months, or whichever comes first — plus one-tap template packs for compact tractors, zero-turns, ATV/UTVs and generators.
Parts counter card
Filters, fluids, belts, blades and plugs with part number, cross-reference, capacity and price note — tap any part to copy its number at the dealership counter.
Service history that resets the interval
Log a finished job with hours, parts and cost; the interval you pick restarts from that reading, and the record exports as a plain-text service file.

Questions
Is the web version of Hourbook free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Hourbook iPhone app?+
The iPhone app exports a formatted PDF service record; the web version exports the same record as a plain-text file you can print or attach. Photos of part labels and stickers are iPhone-only — the web parts card keeps the numbers, cross-references and capacities. No push reminders in the browser: the Due Board is the alarm, so check it before a parts run.
