Child Tracking Device Jewelry
One-way calls, called "Sound Guardian" in the app's menu, are kind of like the Drop In feature on Amazon Echo devices. Parents use the app to call the watch, and they can hear what's going on around it, but the watch doesn't ring or make any indication that someone is listening in. This worked well: My son's watch called me right away, and I could tell he was at school — but he didn't know I was calling, so he didn't say anything to me. The sound quality was only so-so and varied based on ambient noise.
Even without the firmware update, though, Trax Play is a compelling option for parents who want to keep tabs on younger kids, provided they're willing to live with the limitations of the device (such as the lack of two-way communication features). Features built into the app, such as the AR viewer and geofencing capabilities, make the Trax Play a good choice if you want to check in on the location of young children.
The History feature lets you specify an exact period of time and see all the tracker's locations during that time plotted on a map. This same feature works in the web app, where you can also download the history as a PDF or CSV file. The web app can also be used to locate the tracker, set up zones, view alerts and create Access User accounts that are limited to locating the tracker only — everything the smartphone app can do. This is a great feature in case you happen to misplace your phone along with the tracker.
PocketFinder's battery life varies widely based on how often the device pings the server with its location, a frequency you can set. By default, when the tracker is moving, it sends its location every 10 seconds for 3 minutes straight, then takes a 10-minute break. When it's not moving, PocketFinder goes to sleep.
Design: We considered the size of the GPS tracker and whether it was something a child could easily carry around. We also looked at durability: Could the device withstand rough-and-tumble trips to the playground?
The Buddy Tag uses Bluetooth instead of GPS, making it one of the more affordable options on this list. While you can use it in as a normal kid tracker, it's also touted as a device that helps prevent drowning. There's a panic alarm for the child to contact parents if they're in a threatening situation, along with a personal ID to help reunite a lost child with the parents.
Other kid trackers will soon become available. LG Electronics unveiled a new GPS wearable dubbed the LG KizON, which goes on sale Thursday in South Korea and will debut in North America and Europe in the fall, reports CNET. LG -- which already offers the LG G smartwatch and the LG Lifeband Touch, a waterproof wristband -- says it the KizON can run for 36 hours on a single charge and works on Wi-Fi, 2G and 3G networks.
