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.

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.
