Good little app and integrates well in Agama launcher. There are a few issues that need to be resolved though. Inputting parameters in the settings is difficult on a head unit due to layout. Units need to be miles, degrees C and liters, current options are KM, L, degrees C. If these are fixed then it'd be 5 stars from me.

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 Wi-Fi 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.

This is cool, but I still use a second phone to display dash command app. This has a way to go before it will catch up to that. Also, I use an android radio, so I can use navigation like Waze on it. Maybe it's cool if it records keeps data on the background or something but dash command is more comprehensive, especially when the radio is already "in use"

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.

There is no option from the app to search and connect to the scanner. You can only connect to devices which are already connected via system settings. But in most cases you can't connect scanner to the head unit directly in settings. You have to do it using option to search for new bt devices directly in the app. And here there is no option to do this.

Paid for this app as recommended by my car android app, and it will not connect to my Bluetooth OBD Wasted my money. I wish I could get my money back.

Can't purchase the integrate option for Agama Launcher from Google play or website. Needs a full purchase option instead of in-app or make PayPal a method on the website. Or just make an Agama + Crab Pro Bundle.
