On Apollo, it was configurable what swipe actions did what.
The way I set it up was swiping right (icons on left) had upvote at a short swipe and save at a long swipe. Swiping left (icons on right) had collapse current comment at a short swipe and collapse entire comment tree from top parent at a long swipe.
I believe everything, no matter what you personally configured, was in the ... menu as well. Since I rarely would downvote, and reading and saving/upvoting was more common for me than replying, I liked having the freedom to choose this setup. I think being able to customize the swipes similar to Apollo would allow more people to choose what works best for them.
I don’t really enjoy these activities on their own, but I do enjoy some activities that I can do in conjunction. Listening to music or podcasts can be done at the same time as almost any workout. If you are working out at home, you could even watch tv or something. I enjoy being able to play a game or browse the web on my phone if I’m using a stationary bike. Basically what makes it tolerable for me is what I can do at the same time.
