The iOS app has been pulled. The Inspire 1 app was pulled due to the issue with sending video to the iDevice over USB, which is also what the Lightbridge app does, and is against Apple's rules. I deleted the app and tried downloading it again via the QR code but received the message "'Lightbridge' could not be downloaded at this time." (I was able to reinstall it from a backup I had made, but it's not available on their website.)
