This app is only available on the App Store for iOS devices.


Now a Universal app for iOS 9.

Need a quick reference to the geologic time scale of Earth's history? Find out, for example, when dinosaurs ruled the world or when reptiles first appeared. This is an excellent reference for students, educators, professional geologists, or anyone interested in geology.

This is an easy, quick way to get the names and numerical dates of each of the eons, eras, periods, epochs, and ages. Just select which view you want and then scroll through the time scale.

No internet connection required. Ideal for field use.

The Geologic Time Scale Without Ages shows the names of eons, eras, periods, and epochs and their corresponding dates. Touching the With Ages button adds the names of the ages within the epochs along with their corresponding dates. Information icons appear at several points on the scale. Touching each of these icons reveals additional information about which phenomenon occurred at that time such as the extinction of the dinosaurs at 66 Ma.

What's New in Version 1.1

Updated the time scale to use the 2015 International Commission on Stratigraphy names and dates.

Great App

Great reference to have, offers good information. I'm glad this app has been updated and works now. The scale is intuitive and easy to use while still offering interesting information such as origins and evolution of life

Great app!

I received my degree in Geology and I love using this app! It's hard to remember the dates of things, but this app really helps. It's very easy to use. Highly suggest to all professional and amateur geologists.
