Parents know it's more than just ghosts and goblins their kids need to be on the look out for this Halloween.
And now there's an app devoted to keeping you and your family safe.
It's called Guardly, and with a tap of a button it can send emergency notifications to your loved ones, 911 and even pin point your exact location.
You set it up, telling it who to call.
The app doesn't have to be used on Halloween, but it does give you control. If you accidentally hit it, there's a 10 second countdown to cancel.
And another cool thing, the app is free.
