afaik, jerboa's the only option. I actually like the UI for lemmur, but it's abandoned and doesn't seem like anyone's forking + updating it so for the time being, we only have jerboa.
I did see a toolkit that translates reddit API calls to lemmy API calls, which might be useful if any reddit app dev has any interest in translating their app to work for the fediverse, but I'm not sure how likely that is
Jerboa's v.0.0.34 alpha version from their GitHub is better than the Play Store release. It's still alpha, of course, so caveat emptor, but it's been pretty stable for me so far. Some features are still missing. Browsing, searching, and joining other communities and instances is still either impossible or very limited on Jerboa. For that, you'd need to do it on the website.
Speaking of using the website, another option is to just install the mobile version of the site as a PWA (just go to Menu > Add to Phone/Home Screen in your mobile browser), or use an app like Hermit to create a standalone version of the mobile site.
Other than those, there are no other native apps for Android that I know of. There was lemmur, but it's no longer being maintained so I can't recommend it.
