Torque Lite (OBD2 & Car) is a handy app for car enthusiasts and DIY mechanics who want real-time insights into their vehicle's performance and health. By connecting to your car's OBD2 system with an affordable Bluetooth ELM adapter, it provides a wealth of engine data such as fault codes, sensor outputs, and performance metrics.

The app offers useful features including the ability to read and reset engine fault codes, export tracking data to Google Earth KML or CSV files, and a customizable dashboard complete with dials and gauges of your choice. For night driving, the GPS Head-Up Display helps keep your eyes on the road while monitoring speed. Although the free version provides a taste of these capabilities, the paid version unlocks advanced features like horsepower and torque measurements, more vehicle support, detailed data logging, and an ad-free experience.

Torque Lite supports a broad range of vehicle makes and models from Ford to Toyota, though compatibility with newer phones and certain ECUs can be hit or miss. Some users report connection issues on recent Android versions, reflecting the app's last update being several years ago. Despite this, many find it reliable and invaluable for diagnosing common car troubles and reducing repair costs.

In conclusion, Torque Lite serves as a powerful, budget-friendly diagnostic tool for many drivers, but those using newer devices or requiring extensive vehicle support may find it limited. Exploring the paid version might be worthwhile for enhanced features and better compatibility.
