Compared to your kid, Houdini was an amateur. If you avoid crowds and frequent fenced-in playgrounds for fear of losing your little one to the Big Wide World, we’ve got good news. From GPS-enabled smartwatches to innovative child leashes (no judgment here!), there’s a whole range of great gadgets and apps designed to stop little escape artists from disappearing—and how to find them if they do. Flip through the slideshow below to see our top picks.

The Joey Tag

One of the only kid-trackers out there that doesn’t require a monthly subscription, the Joey Tag is a bluetooth-enabled wristband that sends an alarm to your smartphone every time your child crosses a pre-set boundary. Developed by a father and his six-year-old daughter after they got separated at an amusement park, the Joey Tag also comes with a panic button so kids can sound the alarm if they feel threatened (a useful feature if kids are using restrooms by themselves). And, in case you've got the kind of kid who likes to rip off everything you try to put on them, the Joey Tag can only be removed using a magnetized key that parents can attach to their keychains.

Lose track of your tiny escape artist? Use Joey Tag's short-range GPS to track your child's location.

Insider Tip: Since the Tag uses Bluetooth technology (as opposed to cellular), it only works if your child is within range of you—up to about 300 feet, depending on your environment.

Best for ages: 2-7

Cost: $89.99.
