Over the weekend, Evernote for iOS got some nice new features and a heap of under-the-hood bug fixes and improvements. Here’s a look at what’s new.

Get Evernote for iOS (v 4.0.4) from the iTunes App Store

Sharing notes to Twitter and Facebook from your iPhone, iPad and iPod

Having Evernote on your iPhone and iPad allows you to capture great ideas and moments whenever and wherever they occur. Now, you can also share those notes with friends across your entire social graph with a quick tap.

To share, open a note then tap on the share icon. A list of options will appear, including Twitter, Facebook and Email. Both Twitter and Facebook require you to first sign into the respective accounts, then allow Evernote to post. You will only need to do this the first time. Next, you’ll be asked to confirm. Everyone you share with will then be able to view that note.

This is a big step forward for sharing on iOS. Support for shared notebooks is coming soon.

New sorting options for notebooks and tags

If you’re a fan of getting to notes through the notebook and tag lists, we have some new options that will make your experience much more pleasant. In both the Notebook and Tag screens, there’s a new ‘i’ icon in the top left corner. Tap it to view sorting option. You can choose to have your lists sorted alphabetically or by note count. You can also hide notebook and tags that have no associated notes—making your lists more manageable.

Landscape Snippets on iPhone and iPod

We’ve added a new view when you turn your phone on its side: Landscape Snippets. To view it, simply turn your phone when in a list view. You’ll see a big thumbnail, if there is one, and text associated with the notes. Landscape snippets are more information-dense making them great for browsing.

Many, many improvements

This update also includes many improvements to search speed, note caching, synchronization, general stability, and much more. We have lots of great new stuff in the works for iOS. Stay tuned.
