B&N just announced they are going to roll out IAP on Nook “soon” (supposedly by mid-April), via mobile-payment provider forutmo. https://nookdeveloper.barnesandnoble.com/iap.html
It would be good if Corona could support this from the get-go. Not to mention the sorely needed Amazon IAP integration. Our paid app, The Bad Girl’s Journal, is doing very well for us on Nook, and the Amazon store version is starting to pick up steam, currently #1 in productivity. We would love to have the option to create a free version with IAP on all storefronts, not just Apple and Google Play where we are having a lot of trouble getting noticed above the noise.
