10 Best Kids Fitness Trackers 2025 in the United States

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 VTech KidiZoom Smartwatch DX4 is a fun and engaging smartwatch designed for kids aged 4 and up. One of its standout features is durability, thanks to its premium metal body and splash-proof design, making it suitable for rough play and outdoor activities. The rechargeable lithium-ion battery ensures decent battery life, though it might require frequent charging depending on usage. Comfort and fit are generally good with its adjustable strap, suitable for small wrists, but it's important to ensure it's not too bulky for younger children.

Activity tracking features include a pedometer, challenges, and reaction games that promote physical activity, although it lacks advanced fitness tracking like heart rate monitoring or GPS. The dual cameras are a great addition, allowing kids to explore their creativity by taking photos, recording videos, and using fun effects. Parental controls are present with features like School Mode and Daily Reminders, helping parents manage screen time and ensure appropriate use. The watch is user-friendly, designed with kids in mind, featuring a large screen and intuitive interface.

The variety of built-in clock faces and the option to download more is educational, aiding children in learning to tell time. The design and style are appealing to kids, with a vibrant blue color and playful elements. However, it's worth noting that the memory storage capacity is limited at 256 MB, which might restrict the number of photos and videos that can be stored. While it has a music player and composer app, its focus is more on entertainment and creativity rather than comprehensive fitness tracking.

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.
