Give me a little credit ...Review this document:https://developer.apple.com/library/ios/documentation/General/Conceptual/WatchKitProgrammingGuide/Tables.html#//apple_ref/doc/uid/TP40014969-CH14-SW1Here's a sample of an app I wrote originally for the iPhone -- and have been playing with on the Apple Watch.It demonstrates how to order take out -- In-N-Out Burger in this example.The way it works is this:you scroll the list by dragging on the screen or rotating the crowntable...
It is much more expensive in processing, transmission and battery to swipe a watch screen and completely replace it with a new screen. With scrolling a list, only the visible rows are refreshed as displayed -- much more efficient.Developers on an iPhone sometimes get a little careless and refresh an entire list (table) with a reloadData() function. You do not have a reloadData() function in WatchKit because it is too inefficient ... Apple wants developers to consider...
This'd be interesting to look at on the morning after the night before ...
My grandson has an iPod Nano 6G that has a watch band attachment:This is a bit larger than the Large Apple Watch, but it only has 240 x 240 pixel resolution.For an interesting read:http://www.dailydot.com/technology/apple-watch-vs-ipod-nano/
If you consider that a useful function of a smart watch (or any computing device) is to select items from a scrollable list -- the rectangular shape is more suited for that.Also, the rectangular shape is more efficient in processing, transmission and battery use (from my earlier post).Additionally there are manufacturing costs -- case, glass, display ...For example, the sapphire screen is cut from a slice of sapphire cut from a round ingot. Say you need sapphire to cover...
That's a very good point -- it is a more processor-intensive calculation to, say, zoom a circular image than a square image ...With current 3rd-party developer watch apps, the calculations are done on the iPhone, then the zoomed image is transmitted to the Watch via BTLE -- so, circular would be a bigger drain on the batteries of both the iPhone and the Watch.I suspect that Apple-supplied apps do the rectangular zooming calculations on the on the watch, itself ...No...
Mmm ... Considering all the advantages purported by the advocates of the circle over the rectangle -- I expect that we'll see some round smart phones ... Real soon now ... The big question is who will make the first round smart prone that sells (or ships) 1 million units ? Maybe they could give it a razor-sharp edge and call it the OddJob S7 Edit: Oops ... Already been done: https://en.wikipedia.org/wiki/Chakram  
Things aren't always what they appear to be ...
My algebra and geometry is rusty ... The example below, determines the area of a circle circumscribing a square of side 4 (units).https://answers.yahoo.com/question/index?qid=20100122090503AA39bY1The area of the square is 4 x 4 == 16 unitsSo:25 == Area of circle (above formulae)16 == Area of inscribed square (given)9/25 is unused (wasted) area of circle ... By eye, I SWAGed that ~ 1/2 the pixels would be unused (wasted) -- I was off by a bit ... I'll leave it to you to...
