Download Terraphone »

There are a lot of apps that teach you how to find stuff that’s already been found…but now there’s Terraphone, the first iPhone app devoted specifically to geologic discovery!

Terraphone is an easy interface to scientific analysis of the world around you. This is –NOT– simply some book in iPhone form…this is a tool that brings ACTUAL SCIENCE to you in a highly-localized way. In other words: You choose a location, and Terraphone teaches you the science about it!

You can:

* Study strata (rock layers)
* Learn where minerals have been found
* Learn where fossils have been found
* Learn where meteorites have been found
* Learn where precious metals were found
* See the scientific analysis of finds
* Learn what layers of rock the minerals were in
* View images of minerals
* Learn about the surrounding terrain
* Learn about nearby geographic features
* Use street and satellite maps


* Earth impact craters worldwide
* Quick web lookups! Almost everything is now clickable so you can do web lookups of unfamiliar terms without ever leaving the app!

Terraphone also includes a dictionary of more than 28,000 geology and mining-related terms – This is a MUST for earth science professionals and it is also a great benefit to anyone who wants to understand geologic terminology.

For a video demonstration of Terraphone, please see:

iPhone world loved it:

“The data available for across the US is very concise…I really like the interface and user-friendliness of Terraphone…if you enjoy learning
about geology, or you are looking for a geology reference guide, this app is perfect” – (Received “Silver” award) – Rob Lewis, iPhone World

…and EVEN MORE has been added since their app review!

Open Terraphone and you’ll be amazed about how much is known and has been found in the earth around you.

Whether you’re an earth science professional, a student, a fossil-hunter, or just a weekend rockhound, Terraphone is FUN and TREMENDOUSLY EDUCATIONAL.

Things to know before you buy:

* Internet connection required to download data, but downloaded data can then be viewed offline through “History” and “Save” functions.
* Images are high-resolution so that you can zoom in and see great detail. As a result, load times vary. Be patient, the longer you wait, the more detailed the image is!

Terraphone not only works for your current location, but you can also study geology all over the United States. (limited data available for the state of Hawaii and many areas outside the US).
