LG Watch Sport, LG Watch W7
I wish there were more tutorials for watchfaces and how to deal with Wear-specific problems: for example, I still don't know how to run a watchface with in Debug mode connected via Bluetooth to my phone, such that I could see the logs... (since both my Wear watches have no direct USB connection, right now I use a wrapper app to download the watchface onto the watch, but I don't know how to access the watch logs then...)
Cheers,
Seong-Han
