Sun Seeker: It shows you the position of the sun in the sky on any date you choose in your current location, including an augmented reality camera view which superimposes the sun (and its projected path) on your surroundings via your camera lens.

Reeder: This is, hands down, my most-used app on the iPhone. It's the best (and the fastest) RSS news feed aggregator available. Basically, it compiles RSS feeds from all the websites that I'm following and puts them in one, easy-to-access place, even if I'm offline.
Available for the iPhone and iPad here.

Camera+: Thanks to this app, the default iPhone camera now rests in the 'unused apps' folder on my iPhone. Very fast load time, it lets you take multiple pictures instantly without waiting for the previous one to save and even has some very competent built-in filters and frames for some basic post-production to jazz up your photos.
