Yes it can block ads for all apps but you need to get the premium version. If you just use the free license it mostly just works on browser apps.
If you are interested in this app then remember to grab it from their website directly and not the one on the Play Store. And if you ever decide to get the paid license you can grab a lifetime license on stack social at a discount.
I use Sync because it was my favorite client for reddit but I'm definitely gonna hold out on paying until there is a sale or something. My usage of Lemmy is not that high at the moment.
Not the person you replied to but I don't evaluate app prices in a vacuum. First I think of what paying actually gets me (e.g. no ads), then I consider how it compares to alternatives both free and paid. A paid app has to provide some value over a free app and an expensive app has to provide some value over cheaper apps. Furthermore if an app is priced such that I can buy 3-4 other apps while also being more expensive than any individual apps I've previously purchased then it gives me some pause.

Well not exactly. The person posting chooses the platform and then other people have to go to said platform. If someone doesn't like platform X and prefers Y then they have to convince others to also switch to Y. This happened with instant messengers and it happens with chat applications.
I think some views like List don't have the ads.
