If you're worried about your kids going trick-or-treating alone this Halloween - there's an app for that.

SecuraFone is a free app that will help you keep track of your little witches and warlocks as they road the streets in search of candy.  Not only will the app update your child's location every few minutes with the GPS tracking, it also allows children to send SOS text messages in case of emergencies.

The app isn't just for Halloween.  Parents can install on their teenagers phone to prevent texting and emailing while driving.

Since my daughter is now driving and has a cell phone attached to her ear at all times, this free app is a great idea.  She may be too old for trick-or-treating, but the GPS tracking device is something that could come in handy.  Better to be prepared for the worst than wishing you had it when you need it most.
