Essential Apps of 2011

Very impressive. Besides your very clever ploy to get us all to see your profile for the link ;-), the landing page is beautifully well done. I found it immediately useful for my own purposes.

Just heard today about a phone app that helps the user practice CPR correctly. It even uses the accelerometer to measure the depth of compressions. (Apparently, there is a comfortable/correct way to hold the phone (fingers of upper hand) while doing CPR (heel of palm of lower hand).

It was mentioned on one or another public radio show, in an interview with a professor or authority in Wales. Actually, there are a few CPR apps; this one is called somethingCPR, IIRC.

Having an iOS version is a lot different than being iOS based. I use Dropbox, Instapaper and Pandora on iOS, but I use the web-based version from my laptop just as often.

I think many if not most people, especially in Wired's audience, access these tools from multiple platforms. If you had a list of "essential" desktop apps or web services, would you exclude those which also had an iOS version because they weren't exclusively on your target platform?
