Your geology, right now

$1.99 for iPhone, iPad, and Apple Watch

Now you have geologic maps and more anywhere you have internet. Go anywhere with GPS, a tap on the map, or search by name. Mancos shows you a geologic map, details about the stratigraphic unit at that location, the regional stratigraphic column (supplied by Macrostrat), and even fossil collections in the area (from the Paleobiology Database).


Strike and Dip

Into the field

$4.99 for iPhone and iPad

Take your strike and dip measurements in one step, measure accurate bearings and vertical angles. Save all of these as editable notes, tagged with your current date, time, and GPS position. Add photos to your notes, too. All your notes and photos are easily retrieved.



Coordinate conversion, mapping, bearing, waypoints, and more

99¢, for iPhone and iPad

Coordinates makes it a snap to convert any position between the four formats for recording your geographic position. Send the location as a text message, view it on a map, or get a bearing and distance that will let you walk right to the location. Even use the GPS to get your current position. Save your waypoints, and export them, too.


Coordinates Lite

Instant, free conversion of GPS coordinate systems

Free, for iPhone and iPad

Coordinates Lite is a great free way to quickly convert between the three formats for recording latitude and longitude: decimal degrees, degrees and decimal minutes, and degrees-minutes-seconds. It couldn’t be simpler: tap the coordinates, edit them, and the conversion is instantaneous.


Jake for Stratigraphy

Measuring stratigraphic sections made easy

Free, for iPhone

No more futzing with hard-to-read compasses and transits. Lay your phone on a bedding plane, and record its dip angle and direction with a tap of a button. Arrows and a bold display show you how to orient your phone parallel to bedding, making measurement of stratigraphic sections so much easier. Works with any Jacob Staff, but especially with our 3-D printed Jacob staff / laser pointer combo.



Ecological counts: easy in, easy out

$2.99 for iPhone and iPad

Taxon makes it a snap to make ecological counts and export them for analysis. Create a census, and it’s automatically tagged with your coordinates, date, and time. Enter notes, add species, and increment their abundances. Diversity metrics are updated instantaneously. Easily export your data, too.
