Your typical Agnostic loves to quote the facts. They can often be heard saying things like “Facts people! - they’re not some made up fairy tale you have to make yourself believe in!”
I should know. now Nothing infuriates an agnostic/atheist than a person that denies the facts of the world while sitting there praising the wonders of their new Tom Tom software for their iPhone. (An aside Tom Tom is nice software and its Aussie version has been nicely updated). It’s like there’s a disconnect between their belief system and the fact that the same science that makes their gadgets work, what, oh yea back to the Apps for Agnostics & Atheist thing.
Most people get annoyed by the creationist in our midst, you know the sort, the ones that date the age of the earth by the generations of people discussed in the Bible. Sure most mainstream religions don’t think the planet is only 6000 years old (after all, the RC’s even think alien life is possible), but there still those literalist out there and the CCI is a good resource. The problem until now has been the fact that you had either jump on the web to get you come backs or carry around a printed tomb - not anymore - now your loved Agnostic/Atheist can whip out their iPhone and rapid fire some answers back at that annoying creationist. (You don’t know how many times I’ve had to correct the Freudian typing of cretin rather than creationist.)
Do yourself a favour and spend that $0.99, if nothing else the peace and quite you get while your significant other browses through it will be worth it.
Molecules is one of those surprising FREE tools that let you see in interactive 3D, right on your iPhone the structure of some amazing molecular structures. Best of all, it’s an open ended source of amazement as you can download new models from the RCSB Protein Data Bank and they’re adding stuff all the time!
Why have I put this in the list? Well because an amazing amount of people just have no idea how much we know about the world on a molecular level and a picture is worth at least a thousand words and because it’s just cool, OK?
Another free app, Google Mobile gets a look in here because it’s just the quickest way to do a search for a fact, and we all know how your favourite Agnostic/Atheist likes to get his facts out. Yes - you can Google from Safari but I like the 1 tap to open, hold it up to my head and speak approach. The best bit is the accuracy of the voice recognition, since it was first launched it’s improved dramatically.
If your Agnostic/Atheist is not the speak their search out loud type, then the quick access to the dynamic search box is still faster than opening Safari.
Rate Them!
Don’t forget people if you like something, spend a few seconds on the iTunes App Store and rate them - this way they rise up the rankings and benefit the developer and maybe it’ll be enough for them to put more effort into the next version.

I've been described as a lost technocrat or a wondering luddite, personally I just like everything that takes us forward.
