Evernote is the one non-Apple application that I have on that little dock along the bottom of my iPod’s springboard. It may not be my most-used application, but it’s one that I always want to have within easy reach.

Inspiration can strike at any minute, or there may be some little scrap of information you need to remember for later. I use Evernote, the ultimate digital notebook, to help me remember. Whether I just came up with a new idea for a blog post, the answer to a programming puzzle, or my favorite item at an infrequently-visited restaurant, it goes into Evernote.

Evernote is a note-taking service (free; optional premium plan $45 annually) that stores your notes in the “cloud.” You can keep multiple virtual notebooks that sync between Evernote’s servers, your mobile device and your computer. There are apps available for iOS, Android, Blackberry, WebOS, Windows Mobile, Mac OS X and Windows.

It’s difficult to describe the awesomeness that is Evernote. You’ll have to try it in order to fully see why its users rave about it so much. It’s ability to store and record pictures, audio clips and web pages along with plain text allows you to store practically any bit of information you might find relevant later. Take a picture of the spot where you parked your car, take a picture of the label on some food item you like, record audio memos of lectures or brainstorming sessions. Whatever you need to remember, Evernote has you covered.
