We introduce a concept of "paid add-ons" for the full version of GoodReader - extra features, not critical for app's main functionality, which could be purchased in app, for an extra charge. We believe that this approach is very fair to those who don't need extra features, and therefore don't have to pay for things they don't need.
The important thing about add-ons is that you don't need to buy them if you don't want to. The app works very well without them.
All our paid add-ons (and the app itself, by the way) can be tried for free using our free GoodReader Lite app.
Currently available paid add-ons and their prices in U.S. App Store (prices will vary in different countries):
* Accessing E-mail servers via IMAP or POP3 protocol - $0.99 * Server-style access to Google Docs - $0.99 * Accessing FTP servers - $0.99
