User reviews

Great Tool!

Never will I need to open a Jupyter notebook everytime I want to calculate some simple cosmology things!

Useful and handy tool

A very handy and useful tool for cosmological calculations.

It would be more interesting if we can add nonzero curvature and radiation terms. Also the (as of now) hypothetical term with w=-2/3 should be added for fun.

Cool

Works well

great tool for being at a seminar

Great tool, I loved it immediately. One important lacking feature is that it doesn't output E(z).

Very educational

Very esoteric for most, but for the educated layman interested in cosmology, this a a really cool tool.
V2.2 seems to have lost the ability to unchain the total mass/energy sum. Do we have to take as fact that Omega is equal 1?
