StraboTools, a free application developed by The University of Kansas, is tailored to enhance geologic field work by providing quantitative data that are typically challenging to estimate on-site. Primarily designed for use in plutonic rocks like granite, it proves beneficial across various rock types and thin section studies. The app's key functionality involves analyzing photographs captured within the app or imported into it.

The app features tools such as Edge Fabric, which generates an ellipse summarizing image brightness gradient orientations, aiding in fabric analysis in deformed rocks. It also offers Color Index for quantitative color determination and Edge Detect for applying edge detection filters to images, useful for highlighting subtle features in outcrops and interpreting edge fabric ellipses.
