There’s only a finite amount of resources to work on apps for a given platform. It works fine for Reddit because Reddit is one of the top websites in the world. If all of Lemmy was a subreddit, it wouldn’t make it into the top 1000 subreddits. Spreading the amount of effort you can derive from that number of users over a large number of apps is a recipe for low quality apps. I’m not saying just have one app, but think carefully about whether it’s better for the ecosystem to simply improve the existing offerings.
