I’m pro supporting devs (I’m also one myself), but I’m even more anti-subscription for software. I’d 100% buy a lifetime subscription for $20, however, $100 for a mobile app is insane in my opinion. The developer can set their prices how they please though, and I’ll continue using the ad supported version until the price comes down.
I wasn’t a Sync user on Reddit, but Relay didn’t make it over to Lemmy. Sync has some of the most non-intrusive ads I’ve ever seen, and that’s coming from someone who is extremely anti-ads. They’re very different from the actual posts and super easy to just scroll past. It’s also very clearly made by someone who is great with UI/UX.
