I actually use several apps. Makes it easier to handle things because most apps start getting glitchy when you’ve got more than 5 or 6 accounts on it.
Sync is awesome, particularly for casual scrolling.
Summit though, that’s the first app with mod tools and the first functional multi list feature. The themes could stand a bit more customization, but it’s a great app.
Connect is a killer. Ties with sync for best looking (though sync has more visual options), was the first with instance blocking, and the dev is absurdly fast with bug fixes.
Thunder is just a great all around experience.
Infinity is another very successful port of a great reddit app. It’s on par with sync for sure.
Alas, none support kbin because they can’t, or rather couldn’t. Artemis is the only kbin app available, and even that’s only possible because the dev is running her own kbin instance while the project is ongoing. Kbin lacked an API for apps to work with. I believe they’re going to open one up soon-ish though. So maybe apps will catch up with that in a month or so.
There’s a handful of other solid apps too, btw. I just went off of my favorites. Liftoff is hugely popular for good reason, as an example. Great app, just not right for me.
