30 October 2015:
We have just moved to a new web site, and content is still pretty thin. The DoseCalc page has the user notes for version 2. As noted on the home page, DoseCalc broke under iOs 9.1. We were busy attending to our day job and working on our mystery project - and failed to test under 9.1 before it was released. The issue is related to some old code dating back to iOs 3. The patching got ugly, so we decided we had to rewrite the app. We are doing so in Swift and plan to make it a universal app with auto sizing to fit the many different iOs devices. We apologize for the inconvenience and the length of time it is taking us to get the new version ready for submission.
