It was changed recently, now upvote works similar to lemmy/reddit (but also adds things to your favourites)

Boost is more for the microblogging side of kbin, it’s like a retweet. (also adds more reputation points but that’s not really useful for anything right now)

Harder to block ads and tracking on an app.

Also, last time I tried it, you couldn’t use the app without being logged in, so they get more data on you than if you were able to browse anonymously.
