I disagree LD150. If you look at what you provided it says you 1) swipe right hit end (the red X) and then 2) use the scroll wheel to scroll down the workout summary to hit done.
Now you hit end (still a red X), then you must tap a second time answering “Are You Sure?” and then you need to tap an X at the top left hand side of the workout summary closing the summary. So now there are three things a user must do to complete a workout.
My personal opinion is that I only want to do the first of these three actions.
If the new Are You Sure? tap has been put in place because the workout end is being triggered by users who are wearing clothing that is sweaty and interacts with the watch unknowingly then provide a switch in settings that users can set to add this last step. I can confirm that I do not have these issues and this added tap is annoying to me.
I also never, ever, wanted to scroll to the bottom of the summary to tap “Done”. I wished it would go away as soon as the display changed back to the clock. Especially annoyed that I needed to scroll down and tap it when I wanted to start a new workout a couple of minutes (or more) later.
These are obviously first world problems and there are others scattered around their products. In this case I can live with the added tapping and I continue to buy Apple products. But I always remember that Apple implemented this design on purpose and that says something about them too.
