You need to know if your app meets the expectations of your customers and if you're providing your customers with what they want and need.

1. Why did more than 60% of our customers stop using our app after a month?
2. Why do 10% of customers continue to use our app after 6 months?
3. Why do 4% of customers continue to use our app after a year?

Understanding why your current customers continue to use your app will allow you to focus on what brings customers back to your app. Focusing on what customers want will improve your app, increase your retention, and enlarge your customer base.

These questions are extremely important to keep in mind when developing an app and for each update. Knowing these answers can be the difference between a successful and unsuccessful application.
