Kitestring is an app on the market whose main goal is to make sure people get from point A to point B safely, and will notify their emergency contacts if they don't. To be fair, this isn't an ingenious, new idea. There are a couple of other apps like it out there. But, in my opinion, Kitestring is probably the best. Unlike bSafe or Nirbhaya, both of which both alert your emergency contacts if you're in trouble, Kitestring doesn't require you to touch anything (bSafe) or shake your phone (Nirbhaya) to let people know that you're possibly in danger. In order for Kitestring to work, you literally have to do nothing.
