About

Strat Mobile

This application allows geologists to measure and record stratigraphic sections directly on their mobile devices. It offers multiple measurement methods, including using the device's camera or a traditional Jacob Staff, and automatically logs location and time data. Users can define lithology types, view statistics, and see section locations on a map.

Highlights
  • Real-time stratigraphic section plotting
  • Measure sections using device camera or Jacob Staff
  • Automatic recording of location, time, and date
  • Define unlimited lithology types with custom colors
  • Basic statistics on lithology thicknesses and percentages
  • View section locations on satellite or road maps

Strat Mobile is a program for iOS devices that enables you to measure and record stratigraphic sections right on your iPhone or iPad. Some of the basic tasks that one can perform with the app include: • Real time plotting of the stratigraphic section as it is being measured. • Measure sections using your know eye height as the “Jacob Staff” by sighting down dip through the device camera. The thickness of the measured interval, of course, depends directly on the dip (as well as your eye height). • Measure sections using a traditional Jacob Staff. The device can determine the strike and dip of the bedding for you with the tap of a button • Measure sections using a tape measure. You enter the tape azimuth, slope, start and end point, as well as the strike and dip of bedding, and the device will calculate the correct thickness automatically. • Automatically record, latitude, longitude, time and date for every interval measured • You can define an unlimited number of lithology types (with corresponding colors and widths) to draw your section and tag your observations • Provide basic statistics on the section measured, including the thicknesses and percentages of each lithology • See the locations of entire sections, measured intervals, and samples on a satellite image or road map. • Provide basic input and output of data using standard iOS conventions Will work on iPhones or iPads. The program will work on iPads lacking a cellular data connection but those devices have fewer sensors and thus cannot be used in automatic data collection mode.

Point your camera at a rock and Geology Toolkit tells you what it is, how it formed and what it is made of, then draws you a labelled pencil sketch of it. One photo, the full story. Powered by a frontier class AI model, it identifies rocks, minerals, crystals, gems and pebbles, explains the formation history behind each one and gives you the geological detail to go with it: Mohs hardness, lustre, chemical formula, companion minerals and more. Whether you're a curious walker who picked up something interesting, a rockhound building a collection, a student preparing for fieldwork or a professional out in the field, Geology Toolkit is a considered field guide in your pocket. What you can do • Identify rocks, minerals, crystals, gems and pebbles from a photo • Read the full formation story: how each specimen formed, over what timescale and in what conditions • Discover the companion minerals commonly found alongside your finds • Turn any find into a labelled pencil field sketch in seconds • Save specimens to your personal field guide with sketches, notes and locations • Get confidence scores and alternative identifications for tricky specimens • Meet a new Rock of the Day every morning, with a daily quiz to test what you've learned • Explore What's Beneath: rock columns for places like the Grand Canyon, layer by layer through deep time Built for serious curiosity • Rockhounds and collectors building a field guide of finds • Geology and earth science students studying mineralogy, petrology and classification • Field professionals needing quick, reliable identification and reference • Educators and parents exploring geology with curious learners • Anyone who's ever picked up a stone and wondered what it was Why Geology Toolkit Most rock identifier apps stop at a name. Geology Toolkit goes further, explaining why a rock is what it is, how it formed and what to look for in the field. Every identification adds to your personal field guide, building a reference you'll return to. Available in English, Spanish, German, French, Portuguese and Japanese. Try it free for 7 days, then subscribe for unlimited identifications, full formation histories, companion mineral data, sketches and an exportable field record. From photo to real geological understanding, one specimen at a time. Terms of Use: https://www.geologytoolkit.com/terms Privacy Policy: https://www.geologytoolkit.com/privacy-policy
