Child Tracking Device Chip
You can tap the Instant Zone button on the map to add a zone around the tracker's current location, so you'll get a notification when the tracker arrives or leaves. Or you can tap Zones in the menu below the map to see the zones you already have and add new ones anywhere in the world. The app supports unlimited zones, and they're very accurate, thanks to PocketFinder's use of GPS, assisted GPS, 3G tower ID and Wi-Fi locating to track indoors and out. I was getting "out of zone" notifications when the tracker was just at a far end of my house, until I made the zone a little bigger.
The Jiobit is small and light, about 2 x 1.5 x 0.5 inches and 0.6 ounces, with a loop that lets you attach it to a backpack, shoe, belt loop, keychain or necklace. After I tucked it inside an organizer pocket in my son's backpack, I had to fish it out only every five days or so to charge it in the USB charging dock.
When I stashed the PocketFinder+ in my son's backpack, which stays put in his cubby while he's at school, the battery lasted nearly two full days. But when he kept the finder in his pants pocket instead, we had to charge it each night. You can customize when you want the tracker to remind you to charge it, to avoid sending your kid off with a tracker battery that won't last all day.
Several features in the Trax app should appeal to parents who want to keep tabs on their kids. The app offers a History feature, which lets you view where a tracker has been in the past 24 hours. That means you can look back and see travel that you might have missed, like a detour to the candy store on the way home from school.
With a combination of Bluetooth, GPS/GLONASS and Wi-Fi, the Jiobit got a good signal indoors and outdoors — the app always found it within a second or two of launching. Tapping the top of the smartphone screen lets you enter tracking mode, where the location updates on the map as the tracker moves, leaving a track between points. Live tracking for long periods will wear down the Jiobit's battery, so the app asks you after 2 minutes if you want to keep tracking or go back to the map, which still refreshes every few seconds if the tracker is moving, just without creating a trail.
The worst part about the PocketFinder is its smartphone app. The interface looks very dated, with an iOS 6-era design and a letterboxed layout. Menus display features that aren't available yet, like one that will alert you when the PocketFinder exceeds a certain speed limit. Other tools are buried; for instance, you set up SOS Alerts in the Power Management section but add the contact details for those alerts in the Account section. The iOS app also crashed every time I tried to add an email address or a phone number from my device's built-in contacts, forcing me to type those in manually.
