I'm working on redesigning my  Watch app and was frustrated that there isn't a segmented control available for watchOS, so I did a little exploration imagining how a control could work on a tiny screen.

Still not sure if it is a good idea, but think this approach certainly has enough promise to continue exploration.

After sleeping on it I think I'm going to shelf the vertical segmented control for now. It just doesn't work on a 40mm, it would take up over half the screen at appropriate touch target sizes. Instead I'm going with horizontal segments with icons. With the "explanation label" as a subtitle for the relevant settings section to make it clear what the choice does.
@_Davidsmith horizontal much nicer. I was playing with something similar recently and in a bid to use native controls I opted for TabView but didn’t love it. I’d much rather use what you’ve done here.
@qzervaas I think my conclusion is that a horizontal, icon based segment has enough size to be usable. This is a watchOS 9+ feature so the smallest it will ever be is 40mm, which means the touch targets are 86pts wide which feels like plenty.
@_Davidsmith I’d still try to fit 5 across without scroll ;)
