Strike and Dip turns your iPhone into a pocket transit. Take strike & dip measurements, bearings, plunge, and all that geological goodness, while simultaneously getting your latitude, longitude, and elevation. Save your measurements as notes, and add photos to your notes. Now also with maps (geological in the U.S. and some other parts of the world) that show the locations of all your saved data. Customizable to how you work: choose between azimuth and quadrant formats for bearings, three formats for coordinates, meters and feet, and three different formats for strike and dip.

Amazing App! Easy to use and precise. I am blown away!

Terrible app!

The numbers this app gives me don't seem to have any relation to reality. The strike and dip numbers I get are wildly off from what they should be. I have run the calibration, yet the app still thinks my phone is level when I have it tilted up about 30°. I just can't figure out where this app gets its numbers! It would be nice to rely on this rather than carry a Brunton, I need accuracy to make it useful.

the worst f the strike dip apps

I have tried all thre Strike Dip apps available in the app store. THe other two work well...this one does not give a sensible reading on my iphone 4. The bearing readings are correct, but the strike and dip are not related to any orientation of the phone. Get one of the other ones instead of this one.
