Best Car Maintenance Apps (2026): 9 Apps Compared

Most of us only think about car maintenance when a warning light comes on or the garage rings with bad news. A car maintenance app turns that around: it remembers when the oil was changed, nudges you before the next service is due and keeps a tidy history that helps when you sell the car.

I've listed nine apps in no particular order, sorted alphabetically, from simple logbooks to apps that read your car's own fault codes. Most are from smaller, independent developers, and the details come from each app's own website. For the hands-on side, my car care tips every driver should know pair well with any of them.

Car maintenance apps side by side

In the free plan column, Yes means the app's own site says it's free to use or has a free version, Trial only means a free trial with no ongoing free plan, and No means the site doesn't mention either. Some apps add extra features as an upgrade, so check the current details in the app store.

Logbook or diagnostic: the two kinds of car maintenance app

Logbook apps are digital service books. You enter fill-ups, services and repairs, and the app reminds you when the next job is due. They work with any car and need nothing but your phone.

Diagnostic apps connect to the OBD2 port under your dashboard through a small plug-in adapter. They read the codes behind warning lights, show live data from the engine and, on some cars, reset service indicators. They're handy for spotting a problem early, but they don't replace a qualified mechanic.

What to look for in a car maintenance app

• Reminders by date and by mileage, because some jobs are due on whichever comes first.
• Room for more than one vehicle if there's a second car or a van in the household.
• Photos of receipts and invoices stored against each job.
• An export option, so you can hand a full history to a buyer or move to another app.
• Backup to the cloud or your own storage, in case you lose your phone.
• For diagnostic apps, a clear list of which car makes and adapters are supported.

Setting up a new car maintenance app

1. Add your car with its registration, make, model and current mileage.
2. Dig out your service book or last invoice and enter the most recent service.
3. Add MOT, tax and insurance renewal dates if the app supports them.
4. Set reminders for oil changes, tyres and any jobs your handbook lists.
5. Log your next fill-up so the app can start tracking fuel use.
6. Turn on backup or export, then check it worked.

Car maintenance app habits that save hassle

The app is only as good as what goes into it. Log jobs the day they're done, while the invoice is still in the car, and snap a photo of anything a garage hands you. Check your reminders once a month rather than waiting for a notification you might swipe away.

Keep the basics going between services too. Checking tyres, oil and screen wash takes minutes, and a clean, protected finish helps when it's time to sell, which is where my guide to choosing a car wax comes in. If something does go wrong on the road, footage from a good dash cam can help with insurance claims.

Car maintenance app data and privacy

A maintenance app knows your car, your mileage and sometimes your location, so it's worth a quick check before you hand over details. Read what the app stores and where, whether you need an account, and whether you can export or delete your records. Some apps keep everything on your phone or in your own cloud storage, while others sync to the developer's servers so you can log in from anywhere.

If you share a car, decide who updates the app. One person keeping the log is better than two people each recording half the jobs.

Do you make a car maintenance app? Tool makers can ask to be considered for a featured place on this list.

Picking your car maintenance app

Decide whether you want a simple logbook, a diagnostic tool or both. Try one logbook app for a month and enter your last service and next few fill-ups. If you like seeing what's happening under the bonnet, add a diagnostic app with an adapter that supports your car. Keep whichever one you find yourself opening.

Frequently asked questions

Do car maintenance apps work with any car?

Logbook apps work with any car because you enter the details yourself. Diagnostic apps need a compatible OBD2 adapter and support varies by make and model, so check the list first.

Can an app tell me when my car needs a service?

Yes. Most apps send reminders based on the date or mileage you set, and some use your car's details to suggest service intervals.

Is a diagnostic app the same as a garage check?

No. It can read fault codes and live data, but a qualified mechanic should diagnose and repair anything serious.

Can I share my car's service history with a buyer?

Many apps let you export your history as a file or report, which makes a useful record alongside your paper invoices.

Do I need a car maintenance app if my car has built-in reminders?

Not always, but an app keeps a full history in one place, covers jobs the car doesn't track and stays with you if you change car.
