Phonly for Windows Phone supports articles download without IE and Mobilizer.

Phonly is a third party client for Feedly, the app that replaced Google Reader after the Mountain View company closed the service last year. Feedly took over and made the app available for Android devices. Unfortunately they did not have one for Windows Phone. However, a Windows Phone Dev built a client called Phonly, which went out of beta recently and is constantly being updated with new features.

In an update posted today, the ability to save articles without Internet Explorer or Mobilizer. With the reading settings enabled, users can read articles offline. Another nice addition is the ability to select an article to mark those above it as read.

• Download full article without opening Internet Explorer or mobilizer (must be enabled in 'Reading Settings')
• Tap and hold an article in a list to 'Mark above as read'
• New settings page layout
