Expensive and still lots of bugs.

Please support proximity lock and unlock. Also please support today widget. App is not cheap but it needs to support more functionalities. Slow connection and it doesnt work all the time. Once I lock my Mac, I cant use the app to turn it on. I need to wake up the machine and then unlock Mac using knock which is quite redundant.
