Explanation:

Demand describes about the productivity i.e., how much consumers wish to purchase in the app/store, at different price points at a certain time interval whereas supply describes the desire of the seller to make profit.

It shows that the seller who supply the goods is willing to produce more for the market in a certain time period. If the demand curve shifted to the left, price will rise and quantity will fall. In the supply and demand graph, the supply is on the x axis and the demand on the y -axis. Both the price and quantity are inversly proportional to each other.
