First of all: Thank you very much for featuring my app/complication on here .
I'm very happy that you like it!
Concerning your problem with it not opening the app when you tap it: This is actually how it is currently meant to be.
The automatic refresh interval is currently set to 60 seconds (I'm not yet sure about the perfect value for that and would be happy about some feedback), but Android Wear does not necessarily stick in order to save battery. Because of this, I set the complication to refresh on tap so you can always be sure to see up-to-date information.
So I actually would not like to change this behavior at the moment. However, what I could do, is to implement a setting, which allows the user to select which tap-action they want to use.
