About

Mentryq

Read full description

Know what needs maintenance before it becomes a problem. Mentryq is a simple maintenance tracker for small engines and outdoor equipment: generators, lawn mowers, chainsaws, trimmers, snow blowers, pumps, air compressors, tractors, ATVs and UTVs, boat motors and more. Tell it what you service and how often, and it tells you what's due next. DUE NOW, COMING SOON, ALL GOOD Open the app and see in seconds what needs attention: an oil change 12 hours overdue, an air filter with 8 hours left, an inspection due in 12 days. Everything else sits under All Good with its next service. HOURS, MILEAGE OR TIME Set each interval by engine hours, miles or kilometers, or by days, weeks, months and years. Or combine them: every 100 hours or 12 months, whichever comes first. UPDATE HOURS IN SECONDS Type the new hour meter reading and every schedule recalculates instantly. Update all your machines at once from the overview. LOG EVERY SERVICE Mark a service as done with the date, reading, cost and a note. The next cycle starts from what actually happened: oil changed at 402 hours with a 100-hour interval means the next one is at 502. Every service goes into the machine's history. REMINDERS THAT FIT Get a reminder before a date-based service is due and when it's due. For hours and mileage, Mentryq reminds you after a reading brings a service close. SET UP IN A MINUTE Add a machine with just a name. Add a photo, manufacturer, model, serial number and year if you like. Quick picks for common services (oil change, air filter, spark plug, blade sharpening and more) save typing. The intervals are always yours. PRIVATE BY DESIGN No account, no ads, no tracking. Your equipment and history stay on your iPhone and in your iPhone backups. MENTRYQ PRO The free version tracks one machine with unlimited maintenance items, service history, costs and reminders. Pro adds: • Unlimited equipment • Receipts, photos and PDFs on service records • PDF service history to share or hand over when you sell a machine • Expense reports by year, machine and service • Advanced reminders: your reminder time, earlier warnings, weekly overdue follow-ups and a weekly nudge to log hours • Category filters Mentryq Pro is available as a monthly or annual subscription. New subscribers to the annual plan get a 7-day free trial. Payment is charged to your Apple Account when you confirm the purchase, or when the trial ends. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings. Mentryq keeps track of the intervals you enter; it does not give maintenance advice. Always follow the maintenance schedule recommended by your equipment manufacturer.
