1) Reading assistance for people with sight impairment. Reddit has granted a pass for some apps on this basis though.
2) Moderation and Modmail. For people on the move, or, for example, where you're in front of a business PC or laptop all day, with Web restrictions or personal use policies. The mobile apps were extremely useful for moderation.
I did use the Boost app, but have moved to the official Reddit one for mod work; it's buggy and prone to erroring when trying to complete an action so you have to keep repeating things to make them 'stick'.
This is why the mods are up in arms because it's hard work at the best of times.
But with two major caveats. This is only for non-profit apps, which excludes almost all of them. For Android there is only RedReader now and for iOS there are Luna and Dystopia left.
And still without any NSFW content.
I refuse to use the official app, and the new site crashes safari in the iOS beta, so Reddit is now dead to me. I’ve dropped by a couple of times but since the changes and blackout all of the good subs I follow are empty/dead. They lost me as a user.
And to be honest, I think old.reddit is also on its way out. It's inevitable. So we're going to experience this shit storm all over again.
I support the protests so I'm trying to use reddit less for news and stuff. But for certain needs I'd scour forums for, since those forums no longer exist, I kind of need to check reddit for some stuff. Things related to my health and such.
