how to estimate the volumes?

Dear Sirs,

we are developing an App using your technology and with your new pricing plans throw us in panic!

we planned to purchase the "classic" license month ago so the price for App Development considered 499$ extra.

our App augment toys, so now we have to estimate volumes. how?

we don't know how many people will download the App..

100? 100.000?

our Customer will pproduce about 1.400.000 pcs but it's only a potential volume.

another question.

we made also a coloring book app, but there isn't a real book.

user will download printable drawings, for free. they'll pay the App.

so.. again, how can we estimate volumes?

We thing the new license model is too complex and it's hard to make offers to customers.

We hope you'll simplify the license model or give volume steps without wait for your answers.

thanks for your support
