Free Car Maintenance App: What One Car Gets
A free car maintenance app is useful when it logs the car you already drive without a paywall on every row. RPMBase does that for one vehicle.
Most people searching for a free car maintenance app are not looking for a trial that expires in seven days. They want a place to write the oil change, the fill-up, and the insurance bill, on the car they already own.
Free software still has a limit. The honest question is whether that limit is the log itself, or a quota around extras. If every service row is locked, it is not a log. If the log is open and Ask, photos, and PDF exports are capped, you can still keep a history.
RPMBase is free for one car: unlimited service, fuel, and expense rows, plus reminders, 5 Ask questions, 1 receipt photo, and 1 PDF a month. Pricing lists those numbers without a second billing system. This note is what that plan is for, and when it is no longer enough.
What free should cover on day one
One car, named once: make, model, year, today's odometer. Then a row for work that already happened. Date, kilometers, what was done, cost when you have it. That is a car maintenance tracker, not a catalog of cars you might buy.
Fuel should not need a paid plan. A fill-up with liters, money, and the odometer is how fuel tracking becomes a list instead of a guess. Insurance, tax, and parking belong in expenses so the year is a sum.
A reminder that hangs off real work is part of the same habit. A floating phone alarm that only says 'oil' is not a maintenance log.
What free does not have to include
Five cars, unlimited AI drafts, and unlimited PDF exports are product choices, not a moral requirement. RPMBase puts those on Premium. The garage still works if you type the row yourself.
OBD hardware, dealer networks, and public listings are a different job. A free log that pretends to be a diagnostic tool usually does neither job well. Best car maintenance tracking apps in 2026 maps those niches. This page stays on the ownership log.
The website calculators stay free without an account: oil change due, cost per kilometer, fuel economy. They do not save a history. The app does.
When the free plan is the right size
You own one car. You can write a row after a visit. You want next due dates on that car, not a family fleet. You export a PDF when you sell or when a shop asks, not every week.
That is most private owners. The log is the product. Ask and the receipt scan are shortcuts. If you never use them, the history is still yours.
When Premium is the next step, not the start
A second car in the same household should not share one odometer. Mixing two histories is how reminders fire on the wrong vehicle. More than one car is a Premium limit in RPMBase.
If you scan every invoice, or you export PDFs for work, the monthly photo and PDF caps will feel tight. Raise them on purpose. Do not start paid on day one unless you already know you need the extra cars.
Download the app from the download page. Free is the default. Billing, if you later want it, is only through the App Store or Google Play.
