ReminDIY

The oil change you meant to write down.

ReminDIY keeps track of what your house, vehicles and equipment need — and works out what is due from your actual mileage and running hours, not a guess at the calendar.

How it works

Set it up once, in about a minute.

The slow part of maintenance tracking is normally the setup — typing in every job and working out how often it should happen. ReminDIY already knows the usual answers, so most of the setup is ticking boxes.

Step one

Tick what applies.

Say what you own — a house, a truck, a tractor, a mower — and ReminDIY offers the jobs that thing usually needs, intervals already filled in.

Step two

Open it and look.

Overdue, due soon, on track. Three numbers, then the list — in the order things actually need doing, across everything you own.

Step three

Tap "Mark done."

The next one is scheduled from the reading you just gave it. The part number stays with the job, so next time you already know what to buy.

Features

Built around one question: what needs doing?

Everything else in the app exists to answer that honestly — which means knowing what you did last time, and counting from it.

Counts from real readings

An oil change due in 5,000 miles means 5,000 miles from the last one — not from today, and not from an assumed 12,000 miles a year.

History you can correct

Typed 391,000 instead of 39,100? Edit or delete any past service. The schedule and the odometer both follow the correction.

Part numbers kept with the job

The filter that actually fits, recorded once. When it's time to buy another, the number is right there — and one tap searches for it.

Whoever did it last

If a shop handled it, keep their number on the record and call them from the job itself, a year later, without hunting for the receipt.

Fuel Economy Tracker

Log fill-ups and the app keeps your running miles per gallon. A number that quietly falls off is often the first sign something needs looking at.

Your data stays on your phone

No account, no sign-in, nothing uploaded. It works on a plane in airplane mode and in the back of a shed with no signal.

The difference

Most reminder apps are just a calendar with your name on it.

Which works until life doesn't cooperate. You drive 3,000 miles one year and 19,000 the next; the mower sits idle through a wet June. A date-based reminder is either nagging you early or letting the job slide — and after a few months of that, you stop trusting it.

  • Miles, running hours, or a plain calendar interval — whichever actually governs the job.
  • Nothing is guessed. If it doesn't know when you last did something, it says so instead of inventing a date.
  • Snooze a job without losing its place in the schedule.
  • What you've spent on each thing, by year, once you've logged a few jobs.
