Why do you think your churn rate is high? Do you know ow what is the average churn rate of other apps or similar apps? (No, your churn rate is not that bad, it is normal in apps). Another good question is the life time value of each customer and how long your users stay in your app (like since they installed it until they uninstalled it). Create an engagement metric for user use case and try to I prove it, more engage means less churn.

Focus on your target market and measure the churn rate in your target market. Forget the rest of the users, those are noise. Develop what you need for your target market.
