Few weeks ago I read a CleverTap article that says 28% of the global apps are uninstalled after 30 days, 21% of apps are used once during the first 6 months. That got me thinking, "What happened?". For some reason, those people downloaded the app from the App Store. They certainly noticed something interesting in it. I have deepened the research, and I found out that lack of value, low engagement, and unfriendly design are the most common reasons. How to deal with those difficulties? Well, app owners should focus on building a successful app from the very beginning of software development. This article will show you how to do that.
