Are payed app sales so low on Windows Store ?

Hello guys, I've made a little app for Microsoft Store (RT & x86/64) and I've decided to put it for $1.50 (the lowest possible).

The app is called Sticky List in case you are interested.

The problem is that in the developer dashboard it shows that the top 5 average paid daily sales are: 24 !!!! This is for the productivity section.

Are the top 5 productivity apps making $24 dollars/day on the Windows Store ? I don't know about you but this is kinda depressing. I've thought about building a more complex management app, but for $24 (that is if i make the top 5) i thinks is a waste of time because the chance of reaching top 10 paid apps is slim without marketing.
