I'm watching both this and Sync with a lot of interest. I'm glad that the guys who made some of the best Reddit clients are going to get a chance with Lemmy. I hope it works out for them.
I never used boost for Reddit, I was using Now For Reddit for nearly the entire time I was active. As much as I loved that app, I think I like this one more. It does have some features that could be better, but the app isn't even launched yet, so I'd assume it's only a matter of time!
I guess I just see a lot of potential in the app. And right now, compared to the other Android offerings, this is BY FAR my favorite.
