Every now and then a post with a question like this pops up on lemmy and I wonder if the Sync company has anything to do with it, because Sync always gets to be the most mentioned answer. It is beyond me why anyone would use an app that pushes ads on you while browsing content from a website that doesn't have any...
ljdawson and rmayayo did great work on their apps, and I purchased both of their apps.
Making software is not easy. I'm a software developer, too. I'm very happy that there is a paid version without ads, I definitely wouldn't use them if I had to use the version with ads.
In my experience, they both provide superior experiences that are both familiar to people and well integrated into Android, especially Sync. Boost has more features however.
If you're looking for a FOSS app, Connect is the next best thing IMO.
I'm currently using the free version. I had the paid version for Reddit, but just haven't purchased the Lemmy version yet.
The ads are really unintrusive though. I think it's one ad every time you reload the feed, about four posts down or so. After that, I think there's no more ads. It's extremely minor, hence why I haven't really felt like I needed to get around to purchasing it.
