interview with Professor Paul Ruvolo from Clew app

in this video, We had a chat with a special guest, Professor Paul Ruvolo from Massachusetts, the developer of the "Clew" app.
"Clew aims to change our world when it comes to indoor navigation.
For the time being, however, "Clew" is only available for the iPhone at the following URL:

From the sounds of it, however, seems like Professor Ruvolo is going to look into bringing it to Android and I can't wait!
