Mac apps I can't live without:

Omniweb
Komodo
Navicat
Visor
Better Touch Tool
Chicken of the VNC (I find the built in vnc viewer horrible, and it hates connecting to x11vnc on my FreeBSD server for some reason)

Can't think of any iPhone apps. I've never really installed many on mine... I do use a few apps regularly, irc999, a vnc app, scan2list

Groceries for iPhone.

My favorite iPad apps:
* Week Calendar HD
* Osfoora HD
* 1Password

On my Mac I use the standard PIM apps (on Lion). I also use BusyCal but unfortunately it doesn't support Exchange in read/write mode.

Divvy - Using the most of my screen estate with aligned windows.

Caffeine - for preventing my screens going asleep when Im on the machine but not typing every minute

Pages and Numbers - Since Open Office is only a weak Mac porting

Mind Node Pro - Simple Mind Mapping

Apimac Timer - Countdown, Stopwatch, Alarm Clock. But takes long to load.

Keyboard Maestro and TextExpander have become essential for me. When I have to use someone else's computer, it feels like a step back in evolution.

Others (that have nothing to do with Omni's products):
Day One for journaling, Ableton Live for music, 1Password for not having to remember everything.

Still looking for the perfect note taking app, so there's a spot open. (Right now I use OmniFocus, but I'm still waiting for Alfons Schmids Notebook to come out for the Mac. We'll see.)
