I have a series of PDF's that I publish. What I need is an iOS (iPhone / iPad) application to display these, a reader. There are some that are free and some that are pay. I'd like to push a notification (user can turn them on or off) to their phone when a new issue of either is avalible. They would also need a sign-in so that the app knows what they have paid for.
There will need to be a nice looking interface with tabs (?) for both free and paid PDF's.
Some way to browse the 'PDF Store' and be able to download free or pay and download the paid ones.
It will need an 'about' tab (?) as well.
I would of course need all original code, or libs etc that are free with no need to display credits.
