I used sync since it's inception on Reddit and it's still my favourite, I've tried 5 different apps for Lemmy but Sync is still my preference. I haven't paid to block ads but I don't get ads anyway so I just get a panel of empty space in it's place.

The app is missing a few QoL features however. It's basically a carbon copy of how it was for Reddit this time last year with all the Lemmy unique functions being on the backend. I also don't expect the dev to return purely because their revenue from the app must be 1000 times smaller than it was from Reddit and they're probably having to adjust to a very different financial lifestyle. However, despite the monetisation, I do respect the Dev as when they're active, basically every rational request gets implemented, and you really get the sense that they enjoithe problem solving of making our ideas work.
