First, I believe that currently there is only one Loops client, the official one. Most of the successful Fediverse platforms have a handful, all developed by different people with different preferences in mind. So, right off the bat, it'd be good if there were more.

Second, and not everyone agrees this is a problem, but Loops has been spammed with TikTok reposts since its inception. Again not everybody minds, but I know a lot of people do.

Third, the official TikTok would be very good to get away from, for lots of reasons everybody already knows. There are already alternative TikTok frontends like ProxiTok that allow one to access content there privately. However, it doesn't actually get people away from TikTok, ultimately.

So I think there should an app that combines your Loops and TikTok feeds, by being a client for one and a proxy for the other. It might cut down on people's urge to repost stuff on Loops, encourage new users to actually try Loops, and maybe even eventually ween some people off TikTok.

The TikTok reposts haven't been amazing, it I agree that Loops needs more content. I think you have a decent idea, though ProxiTok might not be a viable option anymore since it doesn't look like it's had an update in over two years.

Yeah, i think they changed their API to make it muchhhhhh harder to proxy. That said, youtube keeps doing that too, and somehow apps like NewPipe keep managing to fix it somehow
