10 Best Kids Fitness Trackers 2026 in the United States

The Fitbit Google Ace LTE is a solid choice for parents looking for a kids fitness tracker combined with smartwatch functionality. It stands out with built-in 4G LTE and GPS, allowing parents to keep track of their child's location easily, which addresses safety concerns well. The device supports calls and messages through the Fitbit app, letting kids stay connected without needing a phone number, which is a thoughtful feature for younger users. Battery life is decent, offering over 16 hours of use on a single charge, and fast charging adds about 11 hours in just 30 minutes, keeping up with busy kids.

Durability is another strong point — the watch is made with tough Gorilla Glass 3, comes with a protective bumper, and is water resistant up to 50 meters, making it resilient against everyday bumps and splashes. Comfort-wise, the band is designed for kids and should fit well, although the single size may not suit all wrist sizes perfectly. Activity tracking is engaging thanks to movement-based games and the Noodle activity ring, which encourages physical activity in a fun way. Parental controls like School Time allow limiting gameplay during class hours while maintaining communication access, balancing fun and focus.

The touchscreen interface is straightforward, but the smartwatch may feel slightly complex for very young children to navigate independently. The bright and playful design in the Spicy Moovin color is appealing to kids, making it more likely they’ll enjoy wearing it. One limitation is the need for a separate data plan (Ace Pass) to enable LTE features, which adds ongoing costs. Also, messaging capabilities are limited to contacts 13 years and older, which might restrict communication options for younger kids. This device is well suited for active kids whose parents want GPS tracking and communication features built into a durable, fun device, balancing fitness tracking with safety and connectivity, though the cost of the data plan and slightly complex interface might be drawbacks for some families.

The BIGGERFIVE Smart Watch for Kids is designed to cater to children and teens aged 5-16 with its various activity tracking features and parental controls. One of its main strengths is durability, with an IP68 waterproof rating allowing kids to wear it during activities like swimming. The battery life is efficient, utilizing a lithium-ion battery that ensures prolonged use without frequent charging. In terms of comfort and fit, the watch is lightweight at 3.17 ounces and features a 1.8-inch HD touch screen that is easy for kids to interact with. The adjustable strap also makes it suitable for different wrist sizes, ensuring a snug fit for active children.

Activity tracking is comprehensive, with the ability to count steps, distance, calories burned, and active minutes, supporting up to 80 sports modes. Health monitoring is robust, offering real-time heart rate measurement and sleep tracking to keep tabs on the child's well-being. Parental controls are a significant advantage, enabling parents to manage game play through the BIGGERFIVE APP and restrict usage during school hours. The design is casual yet appealing, especially with customizable watch faces that can be personalized using photos.

While the reliance on the BIGGERFIVE APP for extended functionality may be a drawback for users looking for a standalone device without app dependency, the watch does offer puzzle games for cognitive training. However, some parents might prefer a device solely focused on fitness. The BIGGERFIVE Smart Watch for Kids excels in promoting healthy habits, monitoring health metrics, and providing parental control, making it a solid choice for parents seeking to encourage their kids' fitness and well-being.

The Fitbit Ace 3 is a solid choice for kids aged 6 and up, designed to encourage an active lifestyle while being fun and engaging. One of its standout features is the impressive battery life, lasting up to 8 days, which means kids can focus on their activities without frequently recharging. The tracker also offers all-day activity tracking, allowing them to see their progress and earn virtual badges, which can be motivating for young users.

Durability is another strong point; the Ace 3 is water-resistant up to 50 meters, making it suitable for swimming and outdoor play. Parents will appreciate the built-in parental controls that enable them to manage the device from a family account, adding a layer of safety and oversight.

On the comfort side, the design is lightweight and fits well, ensuring that kids can wear it all day without discomfort. The animated clock faces that evolve with activity also add a fun element, appealing to the younger audience. The Fitbit Ace 3 is a good match for families looking to encourage physical activity in their children, with an emphasis on fun and motivation.
