Here in ad agency-land, having an iPhone is de rigueur. Not only does its sleek design pair nicely with our preferred dress code (jeans, ironic t-shirts, sneakers), but it’s become an essential tool for everything from generating and capturing ideas to keeping in touch with clients and vendors.

With so many interesting-looking apps cluttering the iTunes store, we thought we’d let you in on a few of our favorites here at Launch—the iEssentials we simply couldn’t live without.

This month’s must-have is Evernote. Imagine a virtual scrapbook, filled with all your notes, snapshots and voice recordings. Now imagine that scrapbook is automatically synced up online, and easily searchable. Better yet, imagine being able to search for any text appearing in the photos you upload (e.g. the snapshot you took of that potential client’s business card). Now take all of that and bake it into a slick iPhone app, allowing you to read any note, or create new notes that will then be synced back to your computer. And while you’re at it, make it all free (there is a paid upgrade available, in case the included 40 MB of uploads per month isn’t enough).

Yep, that’s Evernote in a nutshell. As a copywriter, I use it to collect all my fleeting headline ideas, visual reference snapshots and incriminating photos of co-workers (you know who you are). And I’ll bet you’ll find it equally indispensable. Check it out at:
