The OBDLink app is a must-have for car owners who want to stay on top of their vehicle's performance. This free app, developed by OBD Solutions LLC, is available on the iPhone platform and works exclusively with OBDLink MX+, OBDLink CX, and OBDLink MX WiFi OBD adapters. The app provides a full range of diagnostic tools, including reading and clearing diagnostic trouble codes, displaying real-time data for over 90 parameters, customizable dashboards, and emissions readiness for each US state. It also offers GPS tracking with the ability to plot vehicle parameters on a map in real-time.

The app is user-friendly and supports English, Spanish, French, Greek, Italian, and Czech languages. It provides a full diagnostic report that can be emailed or uploaded to Dropbox. Additionally, the app offers free unlimited updates and is ad-free. However, it is important to note that the app will not function with any other brand of OBD adapter and continued use of GPS running in the background can dramatically decrease battery life.
