Personal safety service for teens

Kitestring calls itself “your virtual overprotective mom.”

It’s a free, text-based service (not an app) invented by an MIT student who was worried about his girlfriend getting home OK.

To use it, you text a time frame to Kitestring. When the time frame has passed, the service sends you a text, asking you to check in. If you don’t respond, Kitestring can send out a customized emergency message to your friends and family.

You can even set up a duress code to immediately alert your contacts if you end up in danger.
