I've been using it over the last few days and I'm pretty impressed with it so far. Before that I was using connect, then sync but didn't like the ads and insane prices, also tried out a few others but ultimately settled with infinity.

I've been using infinity for reddit ever since sync died and I find infinity for lemmy is quite polished and runs the smoothest out of all the apps I've tried, even smoother then sync for lemmy. The only bug I've ran into is trying to press the profile button on the navigation draw at the bottom crashes the app but it still works from the hamburger menu. I like that I have two of the same apps for both reddit and lemmy that are identical in both looks and usage too.

It is available on F-Droid right now. I'm using and pretend to make a donate to the dev.
