Connect is the first app that I used for lemmy. I switched to Boost when I kept upvoting and bookmarking stuff randomly because I was swiping sideways when trying to swipe up or down. I know it can be disabled but I wanted to try something else. Boost looked nice and I like it in general but the ads are pretty noticeable when I let them through (I could block them with adguard). I understand the devs want to earn a bit and simply use Google ads but the quality and quantity is less appealing. I might buy the ad free version of Boost but I don't like to feel pushed to do that because ads are awful, so maybe I'll go back to Connect.
