10 Best Heart Watch For Kids 2025 in the United States

The Fitbit Ace 3 is designed specifically for kids aged 6 and up, making it a solid choice for parents wanting to encourage healthy habits in their children. It offers up to 8 days of battery life, which means less time charging and more time being active—a big plus for busy kids. It tracks daily activity and sleep well, including bedtime reminders and silent alarms. The built-in GPS is a great feature for tracking outdoor activity, though GPS accuracy can vary and might drain battery faster during use.

The Ace 3 is durable and water resistant up to 50 meters, meaning it can handle pool play and everyday spills without worry. Comfort is addressed with a one-size design that’s lightweight and kid-friendly, but it may not fit perfectly on all wrist sizes. The user interface is simple and engaging, with animated clock faces that evolve as kids reach activity goals, plus virtual badges that make fitness fun and motivating. Parents appreciate the family account setup, which lets them manage their child's tracker alongside their own devices easily. However, the screen is relatively small (0.96 inches), so some kids might find it a bit limited for interaction.

The Fitbit Ace 3 serves as a durable, easy-to-use activity tracker that encourages movement and healthy routines, ideal for young children, although it may not meet the needs of those requiring detailed heart rate monitoring or a larger display.

The Garmin Bounce kids smartwatch is designed to help parents stay connected with their children through two-way text and voice messaging and real-time GPS tracking. It’s a solid choice for parents who want peace of mind about their child's location and safety, especially with features like boundary alerts and an emergency Assistance button. The watch is durable and swim-friendly, making it suitable for active kids, and its 1.3-inch bright touchscreen is easy for children to use. Battery life lasts up to 2 days, though heavy use of GPS and messaging can shorten this.

While it does track heart rate, this feature may not be as advanced or central as in some dedicated heart-monitoring watches. Comfort-wise, the watch is lightweight and designed to fit kids well, but the square shape and size might not suit every child’s wrist perfectly. Using the Garmin Jr. app on a parent's phone is essential for full functionality, requiring an active subscription and LTE connectivity, which could be a drawback for families looking to avoid extra costs or phone plans. The interface is straightforward, making it accessible for kids and parents alike.

Additional features focus more on communication and safety than on fitness tracking, making this watch best suited for families prioritizing child monitoring and staying in touch rather than detailed health metrics. The Garmin Bounce offers a dependable, user-friendly experience that balances location tracking and communication effectively, though its heart rate monitoring and battery life may not fulfill all requirements for a heart-watch-focused device.

The BIGGERFIVE Smart Watch for Kids is a versatile and feature-rich device that caters well to the needs of children aged 5 to 16. Its heart rate monitoring and sleep tracking functions are designed to promote better health and wellness in kids. The watch offers GPS tracking via a smartphone, which is useful but may not be as effective as built-in GPS for real-time location tracking. Durability is a strong point, with its IP68 waterproof rating making it suitable for swimming and other water activities.

The watch also includes 80 sports modes, enhancing its appeal for active kids. Comfort and fit are addressed through its lightweight design (3.52 ounces) and adjustable strap, ensuring it suits various wrist sizes. The 1.8-inch HD touch screen and customizable watch faces add a fun and personalized touch, making the device engaging for children. However, the user interface might require some initial guidance from parents, especially for younger children.

Additional features such as puzzle games can be controlled by parents, providing an educational and entertaining aspect. The option to use the watch with or without an app adds flexibility, though using the app unlocks more functionalities. On the downside, the reliance on a smartphone for GPS might limit its effectiveness for some users. The smartwatch is a good choice for parents looking to encourage healthy habits and activity in their children, while also providing safety and entertainment features.
