Work on marketing? Follow up with churn users? Talk to users, or what?
From my experience, building more features can't grow faster. It's just not addressing the real issue
Would highly suggest talking to users! Either that or exit surveys. You probably won't get that many responses, but every now and then I do and it provides some good insights!
In response to customer requests, I talk to users almost on a daily basis. Most of the time, users discover bugs or get stuck with technical issues. I can fix the issues quickly. What exactly should I talk to users? Or what did you try?
I ask them specifically what went wrong! Why did they decide to stop using my app and what was the decision factor (ex. was confusing). I also ask what they use instead.
