Where to go from here?

Hey there y'all!

Have occasionally lurked here for a while, but now I'm here to post. So I'm currently working on starting up an app development business, primarily using Flutter. Over the past month or so I've been working on a couple different mobile apps and one of them kind of took off unexpectedly, and I'm not quite sure where to take it next. I have a big TODO list of things I need to add to it, I have ads placed on it and that's about it right now.

Today I had a really amazing experience though! Somebody rated me at a 3.0 star, reviewed it, and complained about a few issues & complimented the app. Shortly after I got the notification I read their review and got to work on some of the issues (some were already fixed). Published an update and left a reply for the person. That felt pretty good, "I did a good thing and fixed these bugs!" It gets better. They updated their review and left a really nice message about being quick to fixing issues and being dedicated! This made me so happy and that honestly fueled the next few hours I was able to work on it.

I guess my question is: What's next? Just keep updating my app and see what happens? Start doing more marketing to get more downloads? I don't know..

If you have an Android and you're curious about the app or want to check it out, you can find it here: https://play.google.com/store/apps/details?id=com.g33kidd.pros_cons I'd love to know some of your thoughts on it.
