10 Best Fit Tracker For Kids 2026 in the United States

The Garmin vívosmart® 5 is a durable and comfortable fitness tracker, ideal for kids due to its robust build and swim-safe design. The band is interchangeable, allowing for customization and easy replacements, which is perfect for active kids. The battery life is impressive, lasting up to 7 days, ensuring it doesn't require frequent charging, which is convenient for both kids and parents.

The tracker features a bright, larger display and a simple touchscreen and button interface, making it easy for children to navigate. It offers extensive activity tracking features, including steps, calories burned, intensity minutes, and sports profiles like walking, running, yoga, and swimming. This breadth of tracking supports a child's varied activity levels and interests. Parental controls are enhanced with incident detection and assistance alerts, providing peace of mind by sending emergency messages and live location information when needed.

The vívosmart® 5 also connects to a smartphone's GPS for tracking outdoor activities, although this means the child needs to carry a connected phone for full functionality. The design is simple but stylish, with a unisex appeal, and the device is lightweight at just 24.5 grams, making it comfortable for all-day wear. While it excels in many areas, it's worth noting the limited memory storage capacity of 28 MB, which might affect the amount of data it can store before syncing. Also, the Pulse Ox feature is not available in all countries and is not a medical device, which might limit its usefulness for some parents. Despite these minor drawbacks, the Garmin vívosmart® 5 is a strong contender for a kid's fitness tracker, offering comprehensive tracking, ease of use, and safety features, making it a valuable tool for promoting a healthy lifestyle in children.

The Fitbit Ace 3 Activity-Tracker for Kids stands out with its impressive battery life, lasting up to 8 days, which ensures kids can spend more time being active and less time charging. The tracker is designed for durability, being water-resistant up to 50 meters, making it suitable for various activities, including swimming and outdoor play. Its comfort and fit are tailored for kids aged 6 and up, and it comes in a fun Black/Racer Red color that is appealing to children.

The device includes engaging features like animated clock faces that motivate kids by growing as they move more throughout the day, and virtual badges that celebrate their achievements, fostering a sense of accomplishment and encouraging healthy habits. Activity tracking is comprehensive, covering all-day movement and sleep, with added benefits like sleep tracking, bedtime reminders, and silent alarms to help kids develop healthy sleep routines.

Parental controls are robust, allowing parents to manage the device through a family account, ensuring safety and ease of monitoring. The tracker is user-friendly with a simple interface and Bluetooth connectivity for seamless integration with smartphones. However, some potential drawbacks include its relatively small screen size of 0.96 inches, which might be less comfortable for viewing detailed information. Also, while the rectangular design is practical, it might not cater to kids who prefer more stylized or varied designs. Despite these minor limitations, the Fitbit Ace 3 is a strong contender for a kid-friendly fit tracker, balancing functionality, durability, and engaging features to support a healthy, active lifestyle.

The JrTrack Limited Smart Watch for Kids by Cosmo is designed with both safety and connectivity in mind, making it a solid choice for children aged 6 to 12. It combines a kid-friendly phone with GPS tracking, so parents can easily call, message, and monitor their child’s location through a dedicated app. The inclusion of SOS alerts and customizable safe zones adds an important layer of safety. For activity tracking, it offers basic goal setting, which encourages kids to stay active without overwhelming them with complex metrics.

Comfort-wise, the watch weighs just under 6 ounces and features a 1.4-inch rectangular screen, which is compact enough for small wrists but may feel a bit bulky for very young or slender kids. The design is simple and practical, though it may not be as colorful or playful as some other kids’ trackers. Battery life is decent but depends on cellular usage since it includes unlimited talk, text, and data via COSMO Mobile—plans start at $9.99 per month. This means you’ll need to maintain a service plan for continuous use, which is worth considering for budget-conscious families. Setup is straightforward, but activation is required, which could be a hurdle for less tech-savvy parents.

Parental controls are strong, allowing trusted contacts and managing communications, which adds peace of mind. Some users have noted that the network coverage and app reliability can occasionally be inconsistent. While it may not be the highest-rated smartwatch, its blend of calling, GPS, and safety features makes it a practical option for parents looking for more than just a fitness tracker in a child’s wearable.
