What are the differences between FeedDemon Lite and FeedDemon Pro?

FeedDemon Lite is free ad-supported software which contains a subset of the features found in FeedDemon Pro. Features available only in the Pro version include:

My Stream
Quickly receive and view new articles in your most important feeds - great for frequently-updating status feeds such as those from Twitter and Facebook. Tell me more...

FeedStation
Download multimedia files and have them automatically copied them to your iPod or other portable media player. You can even schedule your downloads so they happen overnight - when you wake up, you'll find new content waiting for you. Tell me more...

Prefetching
Prefetch the images and web pages linked in your unread items so they're available when working offline (without an Internet connection). Tell me more...

Content Filters
Instead of seeing every single article in every single feed, create a content filter which automatically hides articles that don't interest you. Tell me more...

Newspaper Styles
Customize FeedDemon by selecting from four different newspaper styles, and assign different styles to individual feeds, folders and watches. Tell me more...

Secure Feeds
Subscribe to authenticated feeds, including Twitter OAuth feeds and Intranet ("behind the firewall") feeds.
