Have you checked out wefwef.app? It's a browser based app (type it into your browser and then add it as an "app" on your homescreen), which I don't normally like, but it functions fairly well. It doesn't quite look like RIF and instead has more of an iOS look to it...but it is also more "bare bones" in appearance than other Lemmy apps seem to be. So it's simple look reminds me of RIF in a way.

So far I've only tried out a few apps tho personally. I'm still hunting for my daily driver as well.

Edit: It does have some missing functionalities but the devs seem quick to add new features

I'd say check out connect and liftoff

Jerboa, set to list view in the top right menu is super close, IMO.

Liftoff is working pretty well for me. Supports multiple accounts, fairly intuitive UX.

I'm using Connect for Lemmy right now. While it has a card node, you can switch to list.

It''s still not a perfect equivalent, but it kinda... gets close, I guess? 🤷

I'm using Jerboa as well for now. I'd say we'll have to wait a month or so before the dev's who had Reddit apps move to Lemmy. I know the devs of "Sync for Reddit" and "Boost for Reddit" are making Lemmy versions of their apps so fingers crossed more devs follow suit!

There's several clients in the works - I'll be looking at Sync for Lemmy, as I was a customer of Sync for Reddit.

I tried Jerboa and Connect but having most success with wefwef. They all work fine but wefwef just feels most familiar.

I come from RIF too. I tried jerboa but I'm using thunder with compact view now

I know that Sync for lemmy is being worked on, but so far I have been using Jerboa and its just ok, not great.

I’m using Memmy at the moment. It was heavily inspired by Apollo for Reddit (which I used) so I’m happy enough. There are a couple issues still (it’s still hinder development) but as long as you ignore errors when posting and don’t try to resubmit it seems pretty stable to me.

Thunder with compact view or Jerboa are the closest atm.

Honestly Thunder has some really great features like swipe to upvote, but I'm missing things like one handed zoom, jump to parent comment, comment sorting, etc.

It's an alpha though, and the Dev is pretty active. I imagine it'll get these things in time.

Slightly off-topic. I was a RIF user but switched to RedReader, which still works, and can be just as minimal.

Echoing some other sentiments from here, I used RIF and am currently using wefwef.app. I've only tried a couple, but I like this one quite a bit. Just go to Settings > Install App
