Fitness trackers are extremely popular with adults, who use these devices to track their daily physical activity, cardio burn, and calorie intake. So it was only a matter of time before the market expanded to include a similar product for children. A company called X-Doria has just announced the upcoming release of their new KidFit, an activity tracker geared for children ages 5 to 13, according to a new report.

It's a little different from the trackers made for use by adults. KidFit tracks sleep, but not steps or calories. The device sets a daily goal for children: to earn 100 points which they can rack up by being active. Parents can also use the customization feature to set a goal for the child. The device features an app that shares words of encouragement, urging kids on toward their goal — and when they reach it, they get a verbal high-five with a congratulatory message. It will retail for $49.99; come in black, yellow, aqua, and hot pink; and will hit stores in mid-August (you can also pre-order it).

Another company getting into the mix is Leap Frog. Their LeapBand activity tracker for kids 4 to 7 years old tracks activity and issues challenges in Leap Frog fashion — "wiggle like a worm." The child's activity is rewarded with points. Leap Frog announced that its product will be available later this year and retails for $39.99.
