StevenG I know of this app, and actually have it installed. It works real good, but you must capture 3 bracketed exposures and then "post process" to get a resultant HDR. Because of the Post processing, it is considered at not real time like what the iphone can do.

Well, actually, the "realtime" HDR of the iPhone isn't true HDR. It's only capable of extending the DR with about 1 EV but no more, while with the traditional two bracketed shot approach you can easily achieve even more than 8 EV's.

I've published several shots proving this - see for example the HDR images in section " 2.1 The stock Camera client" linked from my latest iOS bracketing / exp. comp. article at http://forums.macrumors.com/showthread.php?t=1621351 (and will also thoroughly elaborate on it in my future HDR bible.)

An example:

When exposed for the darkest area, the HDR of iOS produces much worse results:


and, when metering the brightest area, the results are also very bad:
