Does not work
This application did work at first when installed, but the next day, I found it working without having done anything on the watch or the iPhone. May be it is due to some changes I made to my Gmail account configuration, but I really don’t know what. After installation, messages were all scrambled html code. Now it’s working fine, displaying messages much sooner than Gmail on my PC. I will add a 5th star when it will allow sending emails like the Apple mail client.
