looks like a nice-looking version of the Yet-Another-Watch-Thing connected to an app. i am always confused by the utility of said app... it looks like i'm supposed to be looking at my phone while i'm doing my workout to get the tips it's suggesting, but i don't want to do that.
Well there are waterproof Bluetooth ear-phones, maybe even Wifi ones. Though it's preferable if the former use the classic channels so the range is up to 300feet (~100m) or you could install the app on a waterproof Android watch.
