Flash Notifications for All

This uses a smartphone’s camera flash function to alert the user to incoming calls, text messages, and unread messages. The user can also set the flash to operate when notifications are received from other apps. For example, the Flash Notification app indicates when a message is received on Facebook or Twitter, or when an email is received.
