I have uploaded many item on codecanyon but it is rejected always.

Before 2 days ago I have upload a new item which is rejected by reviewer by saying this -
Here is the feedback from our review team:

This item has a nice concept, but this isn’t the kind of submission we’re currently looking for. The functionality provided here isn’t really what we think is in demand.

Now please help me to fix this and resubmit.

Demo RTL ?
