About this app

We created a simple OBD scanner with a user-friendly, visually pleasing interface so you can enjoy driving without being distracted by complex settings. Display key performance parameters of your vehicle directly on your car's screen or Android device. Set acceptable ranges for parameters, and the system will automatically notify you of any deviations.

The OBD scanner is available as a free app, so you can test all its features right away. But if you want a little extra, try integrating it with AGAMA Car Launcher for a small one-time fee.

This integration extends the concept of a "unified interface" for all in-car apps. Music, navigation, radar detector, and now OBD data can all be displayed together in a cohesive style right on the main screen. This looks aesthetically pleasing and makes system management much easier while driving.

CRAB takes up only 4 MB, and when integrated with AGAMA, it won’t even launch its own interface. We’ll run only a background service that automatically connects to OBD and starts sending data to the interface without any input from you.

Take control of every mile of your journey, enjoying peace of mind and confidence on the road.

Will not connect to integration. App will ONLY work in free mode after connecting through settings on app. NOT the android Bluetooth. Also will not allow me to purchase integration mode. All cards Visa, MasterCard,etc. Confirmed with support these are accepted payments but it will not go through and after attempting you need to reconnect as device looses connection. Also have tried with (3) different Bluetooth OBD2 scanners in case it was the devices issue and it seems to be within the app.

Great addition to Agama Car Launcher with a space for improvements. First, note - if you can't connect BlueTooth dongle there is a high chance the problem is in your car unit, try other apps and see it if works. In my case I had to purchase WIFI dongle, as bt dongles is not supported by my unit. Second, the app is great, but I would love to have more than 6 sensors in Agama. Also, I suggest customers to set odb2 control button in one of the corners, for fast switch and Crab status.

I can use the free mode to see various live data found in many stand-alone OBD apps. Try to pay for the integration features and all forms of payment say unavailable, including Google Play credit (assuming region blocked by the play store as I'm in the U.S). Since AGAMA is, BY FAR, the best and most clean car launcher, I really want the integration features to work. Please also add WAZE integration and tutorial to use the radar scanner integrations. Thanks for the continued excellent apps!
