Say augmented reality to any iPhone owner and they'll say Wikitude or Layar. A detailed scan through the appstore shows there are more browsers than any other category of mobile augmented reality application. We continue the ultimate guide to iPhone augmented reality and focus on the augmented reality browser. Are there any threats to the Wikitude crown? What's hot and what's not.

I was on holiday when WhereMark hit the iPhone store in December but I was in contact with the developers back in September when they released a preview video to Youtube and remember being excited about it. Having had a chance to test the released version I have to say they have done a pretty good job and lived up to my expectations.

WhereMark is a new augmented reality browser application that is coming to the iPhone soon. Like all the other world browsers out there WhereMark shows you what is around you in your current location, but WhereMark has a few differences that will make it an interesting alternative.
