It works I guess. The experience leaves so much to be desired. Biggest problems I've had are calls not ringing or if they do ring my entire phone audio output is stuck as call audio until I release all Bluetooth connections because the app doesn't communicate with the Android Audio APIs well, which is I guess the jist of this review: the app doesn't work well.

There are so very few things you can adjust with this app & I dislike the layout, the fact that my phone can't control the settings, and as of a few days ago I don't even get the whole screen to come up when a call cones in. On the tiny ribbon I get, it takes forever for the data to scroll so I can see who is calling. If I had another option, I'd use it!!!

Went from usable to terrible. I get multiple instances of the same one incoming phone call, then the call drops completely. No matter the setting, none of the calls ring. Even if you have the application set to run in the background, and set to use data regardless, the app disconnects completely everytime the window is minimized. You can have the app open, staring at it, and you'll get an automatic missed call when it never even rang. Don't waste your time or your company's money.
