Strike and Dip 2
Take your iPhone into the field
Take your strike & dip measurements in one step, and save them as notes. Take bearings as you would with a pocket transit, or take them using your iPhone’ camera. Strike and dip keeps your field notes, with every note tagged with your GPS coordinates and the time and date. Edit your notes right on your iPhone, and email them to yourself in a comma-delimited file that can be opened by almost any data-analysis tool.

Coordinates
Instantly convert between GPS coordinate systems
Coordinates makes it a snap to convert between the three formats for recording latitude and longitude: decimal degrees, degrees and decimal minutes, and degrees-minutes-seconds. Just enter the coordinates in the format you have and the conversions are made immediately. All three coordinate notations are displayed at once. With a single click, you can view the position you've entered in the Maps application. Coordinates can also display your current position using the built-in wifi triangulation or GPS.
