Does not install on watch os 2.01

I suggest to avoid waste of time and money and dont buy this app. This app doesnt install on my watch with os 2.01, iOS 9.2.

How much worse can it be? Its an untested alpha version and its surprising that Apple allowed it on the store.

For the record - it open on the iPhone but installation process freezes and doesnt progress.
