Sandra Hassan, a student in Lebanon, has recently released an app called "I Am Alive."

With a single touch, the app will blast a tweet saying "I am still alive! #Lebanon #Latestbombing." The goal is to provide easy communication and reassurance to family and friends after a bombing, when phone lines might be down.

Cordelia Hebblethwaite, writing for the BBC, reports:

She launched it on 21 January as "an expression of frustration" at how bad the security situation has become in Lebanon. "I didn't expect that people would actually start using it," she says, but they have. There have been two bomb attacks since it was launched, and dozens of the 4,000 people who have downloaded the app so far have used it for real.
