Price and value are not the same thing. Lots of labor can make something valued, usefulness can make something valued, but as early liberal and Marxist political economists found out the hard way, it's nearly impossible to derive a theory prices from a theory of value.
The price is going to be determined by supply and demand, not by your labor or the usefulness of the app.
There are occasions when you can successfully price a good above supply and demand (when you have a monopoly on a good that isn't easily substitutable), but I doubt you're in that scenario.
