Bulletproof is maybe the first native Google Glass APP – a lock screen for Google Glass. It helps to protect your private data in daily situation where coworkers, children and/or other people around you want to take a quick look at your glass screen. Similar to mobile phones one can still take pictures when the screen is locked.
