When I got my iPad I initially used the official Reddit app, having used it on Android, but then I went and got Apollo since it was advertised everywhere on the App Store. Apple seemed to really like it in particular.
And yeah, they were right. The user experience is so much better on Apollo than it is on the official app. Personal favourite feature was the ability to share an image of the post/comments you want, it made screenshotting comments a lot easier on the iPad.
Oddly enough, I saw some bootlicking "cope-and-seethe" type (apparent) right-wingers trying to muddy the waters on the eulogy post. If that is the future of Reddit then I'm so glad I'm gone from there and glad Apollo won't be a part of that.
I think he needs a break from all this before even thinking about building a new app. Having your work basically get tarnished in front of you, then being dragged through the mud by an arrogant brat in power who was obviously lying to and about you, having to deal with the refund process, that's gonna take a toll on anyone's mental health.
I do hope he can make an Apollo for the federated alternatives like Lemmy and Kbin, but like I said, he needs to sort the closure of Apollo out before even thinking on any new apps.
