Geocompass for Geologists

Free · Designed for iPad. Not verified for macOS.

This app turns your iPhone into a geological compass, a tool for each geologist. It can be used to measure the direction of dip and the angle of dip of geological strata. The app shows the current device orientation in a realtime stereographic projection. The data can be previewed in projection diagrams (Wulff and Schmidt Net) and transferred to your computer. You can add text to the measurements and plot the measurement localities on a map.
