How it works

A better record.
One small step at a time.

You don’t need a perfectly organized glovebox to start. Begin with the car, the mileage and what you know today.

    Add your vehicle.

    Scan the VIN or enter the vehicle manually. Check the details and current mileage.

  2. 02

    Give it some history.

    Log completed service and keep the related records. Review maintenance and safety information.

  3. 03

    Make the next step clearer.

    Ask Opie a vehicle question, review a recorded trip or investigate a code with supported hardware.

Good questions

The details,
before you download.

Start here. Go deeper when you need to.

How can I keep track of car maintenance on my iPhone?

Keep mileage, completed services and reminders together. Louro gives each vehicle a Garage record so you can review its maintenance history and what needs attention next.

Learn more
Can Louro keep my car’s service history and receipts together?

Louro organizes service history and vehicle documents in your Garage. Start with records you have; adding a VIN does not automatically recover every past repair.

Learn more
Do I need an OBD2 adapter to use Louro on iPhone?

You need compatible hardware for a physical OBD-II scan and live vehicle readings. Your Garage, maintenance records and vehicle questions do not all require an adapter.

Learn more
How do I check my car for recalls?

Start with an official VIN-specific check through NHTSA and the manufacturer. Louro keeps recall information with your vehicle so it is easier to review alongside its history.

Learn more
Can I track car maintenance and repair costs in Louro?

Keep service records and review vehicle costs in the features available on your plan. A useful log connects each amount to the work performed and the right car.

Learn more
Does Louro record trips automatically without an OBD2 scanner?

The current release supports phone-based recording with chosen location and motion permissions. Supported OBD-II hardware adds an engine-assisted flow and vehicle information.

Learn more
Can Opie explain my car’s diagnostic codes?

Yes—ask Opie about a code and the vehicle context. It helps explain the information; it does not replace the testing needed to confirm a repair.

Learn more
Can I organize more than one vehicle in Louro?

Louro organizes each car in its Garage. Vehicle limits and expanded features depend on your plan; check the current upgrade details in the app.

Learn more
Is Louro free to download?

Yes. Louro is free to download with optional in-app purchases. Garage+ is an auto-renewable subscription; Apple shows current pricing and terms before purchase.
