## Description

**Carista OBD2** is a DIY car diagnostic and service app that connects to compatible vehicles through an OBD2 adapter. Diagnose and reset dashboard warning lights, read manufacturer-specific fault codes, monitor live vehicle data, customize comfort features, and perform routine procedures from your iPhone.

The app supports a wide range of brands, including Audi, BMW, Ford, Honda, Toyota, Volkswagen, Volvo, and more. Features may include service resets, electronic parking brake retraction, battery registration, TPMS tools, DPF regeneration, basic OBD2 diagnostics, and emissions testing support. Advanced functionality requires a Carista Pro subscription and compatible hardware, such as the Carista EVO Scanner or supported third-party OBD2 adapters.

## Review summary

Carista OBD2 is usable and can customize supported vehicles, especially with external adapters. However, the service is hampered by a costly subscription model tied to mandatory hardware upgrades, compatibility changes, intrusive upsell prompts, reliability issues after updates, and misalignment between advertised features and real availability for some models.

### Pros

- The app can successfully customize vehicle settings and perform desired modifications on supported makes/models when used with compatible hardware.
- It works with third-party OBD adapters, offering flexibility beyond Carista's own hardware.
- For users with intermittent needs, the value comes from paying only when features are required rather than constant usage.
- Overall, it is functional and provides useful features for users with compatible vehicles.

### Cons

- High cost due to a recurring subscription plus mandatory hardware purchases to access full functionality.
- Hardware upgrades and compatibility issues force users to buy new dongles and can drop support for older devices.
- Intrusive ads and aggressive upgrade prompts inside the app detract from the experience.
- Reliability issues after updates (e.g., broken login, difficulty restoring subscriptions) and other maintenance problems.
- Mismatch between advertised features on the website and what is actually available in the app for certain vehicle models / trims.
