Early last year, I posted about an iPad app developed by Mr. Shigeo Saito of the Japan Space Elevator Association (JSEA).  Recently I learned that he has ported this application from the iPad to the iPhone – so, if you have an iPhone (and, I think there are a few of you that do), then this is good news.

The app is only $1.99 and I’m sure it’s well worth the money.

You can find out more about the app here.
