why my app is not popular on appstore?

You finished app uploaded it on appstore and .... nothing happens. You probably was expecting skyrocketing installs and in-app sales but after days,weeks you got some 10,20 installs. And you thinking what is wrong with my app.

The best way to look at this situation is to look at app like art-artifact. Let's say when you have painting picture or sculpture you are not expecting it to look like Rembrant's or Michelangelo's aren't you ? So why it is different in regards of apps ?

Probably because at first look all applications are looking alike and have unified interface and same buttons and UI elements. But the most important things are in details, in iterations between application and user.

The best way to handle this situation is to continue perfecting and creating more apps and make them looks closer to perfect apps every day and learn. As Michelangelo said : "I am still learning."
