Get to know your car. Choose how to care for it.

Get to know your car while it is running well.

The app remains useful after that first reading, whether your car is recent or one you have driven for years. Engine speed, temperature and load, where available, make more sense when viewed together. Choose useful parameters and follow their changes instead of relying on an isolated number.

For example, a temperature reading during engine warm-up has a different context from one taken with the engine already warm. SC OBD2 makes supported data visible so you can decide what to explore. Availability depends on the car and adapter; the app does not automatically determine whether a value indicates a fault.

Start building a reference before you need it.

When something changes, remembering that “it used less fuel before” may not be enough. A history of trips and data actually saved lets you revisit a specific period and compare it with another. You can distinguish a week of short urban journeys from a longer drive, for example, using available distance, duration and consumption information.

You do not need to wait for a problem to build that reference: readings that were never recorded cannot be recovered later. Configure the profiles and recording needed for your use and keep the sessions that matter. Comparisons help you ask better questions; consumption and performance depend on their conditions and are not certified measurements.

Your data on your phone. A licence without recurring fees.

SC OBD2 is a native Android app. Your phone communicates with the adapter and keeps a local history. Once the connection is configured, you can read supported OBD data and view saved history without Internet access; these local features do not require an SCA account. Purchases, Google Play checks, web guides and online services have separate network requirements, covered alongside other processing in the privacy notice.

Free lets you check compatibility, read standard OBD codes and try basic parameters. Full becomes useful when you want to work with those records over time: eligible additional parameters, history beyond Free limits and CSV export from supported views. DTC clearing requires Full and vehicle support; clearing a code does not repair its cause.

Full is a one-time purchase for the life of the app, with no monthly or annual renewal. It does not promise perpetual compatibility, future SCA products or unlimited third-party services. Check the price and terms on Google Play; if you already hold a licence, check its recognition before buying again. Keep a copy of important data and review files before sharing them.

Start with your car and the free version.

Before choosing an adapter, check its exact model, your vehicle’s protocol and the connection supported by the app. An ELM327 label alone does not guarantee compatibility. The guide takes you from finding the diagnostic socket to connecting, without assuming you already know PIDs or protocols.

With the car stationary, connect the adapter following its manufacturer’s instructions, open SC OBD2 and check the connection status. Start with fault codes or a few available readings. When you want to keep their context over time, set up profiles and recording: not everything shown on screen is automatically saved.

One ecosystem, more ways to understand and enjoy your car

The SCA vision goes beyond a single app: making automotive technology and information more useful to people, so they can make better-informed choices. SC OBD2 puts that vision into practice today, with its own features and history.

SCA Runtime, SCAdia and SCAvia are distinct products and developments within this vision. Each has its own aims, features and availability, presented in the relevant sections. The project’s story, its founders and Smartino explain where it came from and where it is heading, while keeping the ecosystem’s future separate from what SC OBD2 offers today.
