Evernote is an extensive application of which the iPhone app is merely an additional tool for creating notes that sync between a web app and a desktop app. The primary functionality of Evernote is to be able to take notes, recall, and organize everything that happens in your day to day life.

You can save memos, photos, web clips, documents, itineraries, and to-do lists among other things. Everything is synced with Evernote and accessible via the desktop app, their website, and of course, the iPhone.

The iPhone app provides four major functions on the default screen. The functions are the primary ways to create or add new notes to from your iPhone to your Evernote database - upload existing images from your iPhone, take new images to upload, record and upload voice recordings, or simple typed text.

When you select notes on the bottom navigation bar, you'll get almost instant access to every note that has ever been created and can quickly search for anything from all of them.

The focus of Evernote is less on organization and getting things done and more on recalling and logging things of note and importance. More than just the iphone app is required to take advantage of evernote's extensive number of impressive features. It's all free - but you'll find yourself limited without fronting a 5 dollar a month or 45 dollar annual fee.
