But what will you give as incentive at Kickstarter? They usually buy a product and prepay it. Since your product does not cost money, you cannot ask for money at Kickstarter for your product. You will use another model?

They usually recieve a counterparty, the counterparty is a free app financed by people .

I personally have no experience with such campaigns other than money for a commercial product.

Looking forward on your success of the campaign.
