Does not work as a stand alone app on watch

From what I can tell from testing this app out, it is very frustrating that I have to have the app open (and in range) on my phone did the watch app to work. All I want to do is count reps or rounds because I easily lose track at the gym. I want to use my watch by itself to count rounds/reps but it wont work. Please update this app so I can tap the watch screen for every reps/round without having to fumble around with my phone.
