Are we alone? Where is everybody?
More than a Drake Equation calculator, DrakeEQ (v6.0.1) provides a simulation of the extraterrestrial question. Use this fun simulator to graphically quantify the number of advanced extraterrestrial civilizations in our Milky Way Galaxy.

Are we alone?: DrakeEQ computes/displays civilization count and draws them to the display.

Where is everybody?: DrakeEQ approaches the Fermi Paradox by positioning the civilizations in 3D space and computing the average distances between them.

DrakeEQ is both educational and entertaining. And at nearly 8 years running, DrakeEQ is one of the longest continuously supported apps on the entire App Store!

Learn about the famous Drake Equation through direct manipulation of its 7 parameters. Easily tweak equation variables using fun drop-down manipulators.
