What Our Testers Say

"One of the best aspects of this activity tracker over most I’ve tested is that you can literally plug the sensor right into any USB port you have on hand. Considering how many chargeable devices we use—and how many still come with proprietary charging cables (looking at you, Fitbit), knowing that this device doesn’t require yet another cable is a major selling point." — Ashley Mateo, Verywell writer and product tester

This one is designed for ages 4 to 9, and it comes in several fun prints including flowers and camo that kids will love. Because it’s waterproof, you don’t have to worry about them taking it off before bath time or when they jump in the pool.

The battery life lasts up to a year without having to charge it, and it can connect to an app on mom and dad’s phone so you can view your kids’ activity.
