Part 1 of 2 (Matt will post his in the next few days).

Jessica’s list of must-have apps: I work exclusively on a Mac (well, two, actually) so these are all Mac-friendly.

Transmit

I was pretty meh on the subject of FTP clients until I tried Transmit. Now I don’t know what I did without it.

Fluid

See above re: FTP clients and switch for site specific browsers. I finally installed Fluid on a whim and…wow, was I ever wrong. It’s given me a whole new appreciation for my Dock.

TextMate

Can’t rave enough about my love of TextMate. Makes coding a breeze.

Google Docs

We keep the majority of our paperwork (contracts, contract templates, etc.) on Google Docs. We can share amongst ourselves and access files from anywhere – handy when you’re constantly shuttling between office and home office. Also: it’s not Word!

Google Apps

We finally switched our couldbe studios email over to Google Apps, and it’s been great.

Basecamp

For all our project management needs.

Highrise

Keeps track of our contacts.

Ma.gnolia

Social linkage.

Firefox

And, of course, what’s Firefox without extensions? I use Firebug, Foxmarks, 1Password and ColorZilla.

Campaign Monitor

Not only does Campaign Monitor make it easy to send and track email newsletters, it makes setting up managed accounts for clients a breeze.

Reinvigorate

I personally loathe Google Analytics, but none of the other free or low-cost offerings seemed much better. Enter Reinvigorate. They’re in private beta right now, but we were lucky enough to get in. And I do mean lucky: Reinvigorate is a fabulous service, and I can’t imagine switching.

DropSend

When we’ve got to email huge files to clients or printers, DropSend is invaluable.

Blinksale

Simple and easy to use. We looked at FreshBooks, but given our requirements Blinksale is a better fit.
