3 stars: when you conciser what it can do, this app (and adapter) are incredibly powerful and can do many things with it. the biggest issue i have is that you have to pay 75CAD dollars a YEAR to use the app to its fullest on top of buying the 100+CAD dollar adapter. i realize that this app has very good future support and is compatible with a wide range of cars, but still leaves a bad taste in my mouth and my wallet
4 stars: -Using on a '08 e92 BMW 335i(N54) Quite impressed with what this app does. It would have been 5/5 but some functionality intermittently stops working. From troubleshooting/diagnostics to changing countless settings(things which would require coding, $). This app is very straight forward and easy to use. It will save any car owner a few trips to the mechanic, no doubt.. not to mention save you $100s, much more in the long term.
5 stars: I was about to give one star for the popups in German language, but they have fixed the issue, so will continue to use. Again, great app when works.
3 stars: Now it stop working requiring you to buy a new universal device. Its nonsense with this carly. I have the second generation device now it can't connect to my Bluetooth
4 stars: Overall the adapter and app works as it should. The only down side that there's no option to bleed the fuel system on my wv passat but for my bmw it works great.
5 stars: Works well for my BMW F30/F34. I am able to make changes to many settings, well worth it for BMW owners...
