CosmoCalc is a simple cosmological distance calculator. With a simple and intuitive interface you can quickly set a reference cosmology and redshift, and CosmoCalc will calculate a full suite of astronomical distances and scales.

CosmoCalc is a useful and educational reference tool for astronomers, astronomy students, and anybody interested in calculating the distance to astronomical sources.

CosmoCalc allows you to:

* Select cosmological parameters H_0, Ω_m, and Ω_Λ with simple touch-screen controls

* Easily choose from common reference cosmologies, including Planck 2013, WMAP9, Concordance, and Einstein-deSitter

* Quickly determine the luminosity distance, angular diameter distance, lookback time, age of the Universe, comoving volume, and critical density

* Easily switch between flat and non-flat cosmologies by clicking on the chain

What's New in Version 3.1.1

Finally updated for large screen iPhones! Other small bug fixes, Planck 2015 cosmology, and full iOS 10 compatibility, .
