10 Best Kids Fitness Trackers 2025 in the UK

The Google Fitbit Inspire 3 Activity Tracker is a strong contender for a kids' fitness tracker, offering a blend of useful features and solid performance. Its durability is notable, with water resistance up to 50 meters, making it suitable for various activities and ensuring it can withstand the rigors of everyday use by children. Furthermore, the tracker boasts a battery life of up to 10 days, reducing the need for frequent recharging, which is a big plus for busy parents and active kids alike.

In terms of ease of use, the tracker features a color touchscreen with customizable clock faces, which can be engaging for kids and easy to navigate. The lightweight design and comfortable fit ensure that it can be worn throughout the day without causing discomfort. Additionally, it includes a variety of activity tracking features such as 24/7 heart rate monitoring, Active Zone Minutes, 20+ exercise modes, and automatic exercise tracking. These features can encourage kids to stay active and make fitness fun. The tracker also offers sleep monitoring and a smart wake vibrating alarm, which can help in developing better sleep habits.

However, the lack of explicit parental control features might be a drawback for parents who want to manage their children's activity and screen time more closely. While it does come with a 6-month Premium membership, providing deeper insights and exclusive content, the ongoing cost after the trial period might be a consideration for some families. The mindfulness and stress management features are a nice touch, adding a holistic approach to health and wellness. In terms of design, the Black/Lilac Bliss color option is both stylish and appealing to kids. Despite being originally targeted at adults, many of its features and design elements make it a suitable choice for children, particularly those who are already familiar with or interested in smart devices.

The BIGGERFIVE Kids Smart Watch is designed to cater to the fitness tracking needs of children aged 5 to 16. It automatically tracks steps, distance, calories burned, and active minutes, supporting 80 sports modes, making it versatile for various activities from walking to swimming, thanks to its IP68 waterproof rating.

Another notable feature is its comprehensive health monitoring. It includes real-time heart rate monitoring and sleep tracking, which can be beneficial in promoting healthier habits among children. The watch also comes with a customizable 1.8-inch HD touch screen that allows kids to personalize their watch face, potentially fostering creativity.

In terms of design and comfort, the watch is lightweight, weighing just 91 grams, and offers a wide range of customizable dials, though the rectangular shape may not appeal to all children. Its battery life, supported by a 300mAh lithium-ion battery, is reasonable for a kids' watch, although regular charging may be needed with extensive use. Ease of use is enhanced by the option to use the watch independently from a smartphone app, though pairing with an app does unlock more features. Parental controls are a strong point, with the ability to restrict game access, ensuring kids focus on learning and activity.

However, there are a few areas where the product might not meet everyone's expectations. While it offers puzzle games aimed at boosting cognitive skills, its educational and motivational features might not be as extensive as some parents hope. Furthermore, the lack of standalone GPS means it relies on a smartphone for location tracking, which could be a potential limitation.

Ideal as a gift, this smartwatch promises to motivate kids towards healthier lifestyles, but parents should assess whether its feature set aligns with their specific needs and expectations.

The ease of use is enhanced by its simple and intuitive interface, which is crucial for younger users. Activity tracking includes steps and active minutes, helping kids stay aware of their physical activity levels, while the sleep tracking feature promotes healthy sleep habits with bedtime reminders and silent alarms. One of the standout features is the animated clock faces that change as kids make progress, adding a fun and motivational element to the device.

Parental controls are robust, with options for parents to monitor activity and approve connections through the Family Account and Parent View, ensuring a safe experience for children. The design is kid-friendly with a comfortable, adjustable band available in vibrant colors, though the small screen size might be limiting for some users.
