Apps are more customizable. The UI also tends to be better. The web app is fine but i find trying to upvote anything closes a post i just opened. Personally, i like seeing full images of things as I scroll by. So something like a webclient isnt very convenient and rather tedious. I’m using a whole bunch pf userscripts on my desktop to improve the pc experience, apps generally do that for me on android.
In the end, it’s user preference. I prefer Jerboa, Liftoff, and Thunder atm.
Alternatively fear.
