I've found is handy app called Appcurl and it basically finds the apps that are right for YOU. Instead of going to the Top 10 list of Google Play which has nothing to do with your preferences and needs it shows you the relevant apps to your lifestyle and preference instead. By the way, most of the apps in the Top 10 lists you already have installed anyway probably. This app shows you apps where you have probably not heard of yet and which will fit your lifestyle and hobbies.
I have discovered many apps for my fitness training and animal apps which I have otherwise have never found.
