Well, now that I'm going from a 3G iPhone to an iPhone 4, I thought I'd try out some of these things.

Which ones are worthy of purchase? I've never seen these things before.

Well, now that I'm going from a 3G iPhone to an iPhone 4, I thought I'd try out some of these things.

Which ones are worthy of purchase? I've never seen these things before.

I've purchased 2 augmented reality apps for my 3GS.

1. Sun Seeker: 3D Augmented Reality Viewer - $2.99
It shows the path of the sun, as well as useful information regarding length of daylight, sunrise, sunset, etc. It's designed to work on iPad too. There is also a free version available.

2. Color Identifier - $0.99
Uses the camera to identify colours of any objects. It provides the name, as well as the hex code.

Personally, I find both of these apps to be very useful. But it depends if it would be something you'd use or need. Anyone else know of any good augmented reality apps?
