Currently my app has a couple of issues with a few crashes a day which I am working to resolve but I don't think that is the culprit. My design is decent, it performs decently and its not too convoluted. I use google analytics to track events but they are more of a way to report how much activity my app gets rather than reports on how people feel about my app.

I have about 500 active users and about 1,300 accounts. I used mail chimp to retrieve feedback about two weeks ago when I had about 200 active users and 400 accounts and I received only a couple of responses from people saying they really liked it, with just a few minor suggestions but nothing really enlightening. Just today I used to the new search keyword feature in the play console that allows you to see by which terms your users found the app. I have two keywords which I am targeting and have a very nice 50% conversion rate but mostly all of my installs come from keywords that are not listed and get placed in the "other" category. So I am a bit lost since I feel like the app could be optimized right now as its still very new before I try scaling out and just churn through more potential customers.

I am looking for advice in general since I work alone but more specifically are there any tools/methods that could aid me? I came across https://www.appsee.com/ which looks great to be able to see how users interact with my app but I was unable to get a response? (maybe they don't like the little guys)
