## Review summary

Overall, users see value in basic diagnostics and maintenance insights, with several praising free version for standard code reading and the app's performance for certain dongles. However, the most mentioned issues are reliability and compatibility: frequent Wi-Fi connection problems to OBD readers, crashes after updates or on startup, iOS/device compatibility hurdles, and a perception that the Pro upgrade adds little value and can be costly. Others cite a clunky UI and missing advanced features. A few reviews note good support responsiveness when issues are addressed. The gist: useful tool but plagued by stability and compatibility concerns.

- Free version covers reading and clearing standard OBD-II codes.
- Easy to identify and clear codes.

- Improved compatibility with various OBD dongles and devices.
- Responsive support team that addresses issues quickly.

### Cons

- Frequent crashes or instability after updates.
- Pro version offers little value and is overpriced or requires repurchase.
- Compatibility issues with iOS versions/devices (e.g., accessory not supported).
- Poor UI/UX and usability.
