X-Doria is a company we normally associate with smartphone accessories, but now it's decided to branch out into wearables. While the jury is still out on whether children should be introduced to the concept of the quantified self, X-Doria wants to help get kids moving with its new KidFit activity tracker. Targeted at children between 5 and 13, the multi-colored slappable wristband scores activities to reach a daily goal of 100 points. Parents are encouraged to set goals using the iOS or Android app, which connects to a smartphone or tablet using low-power Bluetooth and provides feedback on a child's progress via its vivid "Results Cards." The wearable is also splash-proof, holds a charge for up to seven days and like the FitBit or Jawbone Up, can be set to track sleep patterns with the push of a button. While it won't track your kids in the literal sense (there are plenty of GPS-enabled wearables targeted at kids that can do that), it does offer a 24/7 overview of their activities. It'll be available on August 15th for $50 in black, aqua, hot pink, yellow, and red variants. If you get in now (and are one of the first 1,000 buyers), you can pre-order the tracker for $40.
