About

Yard Log

Features
Read full description

Yard Log keeps every piece of outdoor equipment you own running smoothly — without you having to keep a paper logbook in the garage. Track mowers, string trimmers, blowers, chainsaws, pressure washers, tillers, edgers, hedge trimmers, snow blowers, and generators. Yard Log is brand-agnostic — Honda, Stihl, ECHO, Husqvarna, EGO, Ryobi, John Deere, and anything else you own. WHAT IT DOES • Per-tool service schedules driven by engine hours OR calendar — whichever boundary is reached first. • Reminders for oil changes, blade sharpening, spark plugs, air filters, trimmer line, chain tension, bar oil, belt checks, and pump service. • One-tap "Log Hours" — record how long you ran the tool today and Yard Log re-evaluates everything. • PDF owner's manual library so you stop digging through the junk drawer. • Parts inventory with low-stock warnings ("you have 1 spare blade left"). • Lifetime cost tracker per tool. • Spring prep, fall touch-up, and winterization checklists. • Hand off the full maintenance history when you sell a tool — Yard Log exports a JSON file the new owner can import. • Home Screen widget shows the next service due across your whole lineup. PRO UPGRADE Yard Log is free for two tools. The one-time $4.99 Yard Log Pro purchase unlocks unlimited tools, PDF manuals, parts inventory, lifetime cost tracker, JSON export, and unlimited reminders. There is no subscription, no trial, and no auto-renewal. Family Sharing is supported. PRIVACY Your maintenance data never leaves your device. There are no accounts, no analytics, no servers.
