Using veepeak Bluetooth odb2 adapter on my 2012 Honda Civic. The app works very well. Connects fast, displays data pretty quickly too with very little latency. No weird crashes or anything so far. The UI is easy to follow and the customization is very intuitive. Gauge animations are executed very well. The guys at hondata know what they're doing. Great app and good price! :)

Hello. The app is not guaranteed to work for all adapters and cars due to the vastness of the combination. We are working on improving compatibility. With that in mind I will refund your purchase. Please contact us support@obdconnect.net and include your order ID.

Very good app. Havw tried all other Obd2 apps. None mach this in the 3 yeara have used it. Have used it in 3 different çar makes and works well with diesel and petrol. Currently working well in my Volvo. The dashboard haa so many options,plus also has a great graphing display with 2 or 4 graphing options. You can configure the range swttings and go between nigt and day mode. Forget the rest this is the best. Ad free and great graphic displays and choices

What’s new

Rewrote dashcam source code in OpenGL to improve performance. Now you can record up to 4k video using only a third of the battery the app used before.
