Thanks for taking the time to help me, those points will make it easier for me to put together a proposal when I start approaching developers. I realize your time is valuable so feel free to leave it at that if you like. Having said that: What kind of CMS backend is typical for newsstand apps? Are there any free or low cost solutions? Are there some standard libraries for covering subscriptions and payments for these kinds of apps, or is it typical for these to be scratch-built per app? Is this typically a major feature in terms of development time? After reading your questions, I'm confident my app will be on the simpler end of things--black on white, static text-only content with some limited hypertext, small content packages--but I recognize this doesn't necessarily mean a simple application. To be honest, all I really need is the ability to deliver simple PDFs, have them display nicely, and charge a subscription for it. From outside of the app development ecosystem, I naively anticipated this would be fairly simple, but as I learn more this seems less and less true.
