Obd Mary is a car diagnostic scanner, gauge dashboard, and trip computer app that offers a range of features to help you monitor your vehicle's performance. However, to use this app, you need to have an ELM327 Bluetooth or Wi-Fi adapter to connect to your vehicle. It is also important to check all electronic control modules (ECUs) in your vehicle to ensure that the app works correctly. Additionally, if you have a choice, it is recommended to choose version 1.5 of the ELM adapter, as version 2.1 is often corrupted.

To get started with Obd Mary, you need to download the app and plug in the ELM327 adapter into the 16-pin diagnostic connector in your vehicle. Then, switch on the ignition and discover your Bluetooth ELM adapter in your Android device settings. After that, select the discovered ELM327 adapter in the app settings and try to connect. With Obd Mary, you can read and reset trouble codes from OBD2 compliant control units, read live parameters like speed, RPM, MAF, and coolant temperature, and create your own set of gauges using the app as a gauge dashboard.

Obd Mary also offers a trip computer feature that allows you to track your trips with the app and ELM327 adapter. The app logs your trip data, including trip time, fuel consumption, fuel cost, average speed, max speed, and more. If you want to enjoy full functionality without ads, you can buy the full version of the app and support future development and support. If you have any questions or concerns, you can contact the developer using the appropriate button on the main app screen and using the email channel.

Overall, Obd Mary is a useful app for car owners who want to monitor their vehicle's performance and track their trips. However, it is important to have the right adapter and check all ECUs in your vehicle to ensure that the app works correctly.
