The app uses Google Glass timeline cards which use voice commands. With MedRef, Glass users have options to "Set Patient" or "Add Note." The software allows users to track patients using photos or text. You can tell Glass that a patient has specific allergies or requires specific care in the hospital, and the information will be stored for future use. The info can be retrieved by tapping Glass or via facial recognition. The open source MedRef app is available from GitHub.
Apps developed for Google Glass include one that allows videos shot with the device to be uploaded to a YouTube channel, and rumors of a Twitter app for Glass have made the rounds thanks to a tweet that apparently came from a client called "Twitter for Glass".
