In this episode, Dave talks to Dr. Gordon Telepun. An Alabama plastic surgeon, Gordon's other passion is chasing eclipses. Based on his experiences with eclipse photography in Africa, Gordon saw the need to develop an eclipse timing device and did it himself. Now he has taken that concept and turned it into an app for both iPhones and Android devices. It lets you know when significant events are going to happen from wherever you are along the eclipse path using GPS. It is designed to help rather than distract you -- you rarely have to do anything with the phone other than wake it up. Then Gordon's voice let's you know what to look for and when! But better than the app itself is Gordon's infectious enthusiasm about the Great American Eclipse coming on August 21.
