I hope this is the correct location for this inquiry? If not, please move to the most appropriate forum.

I'm looking for recommendations for iPhone apps that will allow me to record my exposure data while in the "field". Heretofore, I've been trying to use the excellent "Analogbook", but for a variety of reasons I am not adept or consistent at writing things down while making photographs. That being said, I always have my iPhone in my back pocket and a good app would be most helpful as I try to keep exposure data and field notes for future reference.

Any recommendations or comments are sincerely appreciated.
