Whew!: How to switch between list view and honeycomb app grid on Apple Watch
From your watch face, press the home button once to open the app screen. Then, press firmly on the display….
Press the List View icon to switch…. The app screen transforms into a plain list

yeah, the day I discovered it, I switched to it. Good riddance to that absurd small-icons format Apple pushed.

@nitinkhanna I had it on my Series 3 and couldn’t understand why the S5 had the grid. Took me a bit to find the instructions. I'm very much a words person: icons just confuse me. (Our stove top has icons representing the elements. I was forever turning on the wrong one, until I added stickers with words.)

did you setup the S5 as a new watch? Coz my settings ported surprisingly well from a S0 to an S5!

@nitinkhanna I don't recall now — a lot has happened in the last week. That's the only real difference I've noticed though. And, I'm really liking the S5!
