BIGGERFIVE Kids Smart Watch (1.8" fitness watch) with heart rate, sleep tracking & IP68

What it is and why kids actually use it

The BIGGERFIVE Kids Smart Watch is a kids-focused fitness and activity tracker with smartwatch-style extras. On paper, it’s built around keeping children moving throughout the day: it counts steps, distance, calories burned and active minutes, then adds health-style tracking such as real-time heart rate and sleep monitoring.

It also aims to be more than a screen that just sits there. There’s a 1.8" HD touch screen and a set of built-in puzzle games, plus the option to use it with an app for parents and extra watch-face customisation. A small practical win here is that it can be used without a phone/app as well, so you’re not forced into pairing straight away.

Key features that matter day to day

Where this watch earns its place is in the everyday metrics kids tend to engage with. Activity tracking is automatic, so you’re not relying on kids (or you) to start anything manually. The watch also surfaces sleep patterns, which can be useful if you’re trying to build routines rather than just chase numbers.

The watch face side is a nice touch: it offers 100+ cloud dials in the app, and you can use your child’s own photos for custom dials. For some families, that’s the difference between “a tracker” and “something they want to wear”.

And yes, there are sports modes. The base description mentions support for 80 sports modes (including walking, running, cycling and basketball). It’s the sort of feature that can make the watch feel more relevant if your child has a hobby or a school sports routine.

Tech side in plain English (so you can check fit)

This is pitched as a kids smartwatch with a 1.8" HD touch screen. It’s described as having IP68 waterproof protection, which is the kind of durability rating many families look for in day-to-day kids wear (rain, splashes and the occasional messy moment).

For phone support, the description says compatibility with Android 6.0+ and iOS 9.0+ smartphones. If you’re unsure about setup, it’s worth checking your household phone model and OS version before committing.

The watch also includes heart rate monitoring and sleep tracking, but as with most kids wearables, the detail and accuracy can vary in real-world use. It’s best approached as a helpful trend tool rather than a medical device.

Usage without the app vs with the app

A key decision factor is how your family wants to run it.

Without an app or phone, the watch can still be used on its own for core fitness tracking, which helps if you want something simple for a younger child. With the app, you can access more functions. The description specifically mentions exploring more features through the BIGGERFIVE app and customising cloud dials, and it also highlights parent-controlled puzzle gaming.

There’s also a practical lock option for games: the puzzle games can be restricted in the app, including the ability to lock the game all the time. That’s a sensible boundary for school days, even if the watch is meant to be fun.

Who it suits (and where it may fall short)

It makes sense if you want a kids fitness watch that covers the basics—steps, active minutes, sleep tracking and heart rate—while also keeping children entertained with puzzle games. It’s also a good match if you’re comfortable setting up the parent side of things for game control and watch-face customisation.

It may not be the best choice if you’re expecting a “grown-up smartwatch” experience with a very broad app ecosystem. This one feels more focused on fitness, sleep, and kid-friendly interaction rather than advanced day-to-day smartphone features.

Also, keep expectations realistic around health tracking. Heart rate and sleep monitoring are included, but you should treat them as indicators and habits support rather than something you’d base medical decisions on.

Practical example: turning activity into a routine

Imagine it’s weekday morning. Your child heads out for school and you’re not trying to remember to “start tracking”—the watch counts steps automatically. Later, after dinner, you can look at whether they’ve hit active time, and the sleep tracking becomes relevant when you’re checking bedtime routines over the week. If puzzle games are a temptation, the app lets you keep gaming under control, so the fun stays in the right window.

What to check before you buy

Before buying, double-check a few essentials: your phone compatibility (Android 6.0+ or iOS 9.0+ is stated), whether you’re happy using the app for extra functions and parental controls, and whether IP68 waterproof protection matches your expectations for everyday kids wear.

It’s also worth thinking about the age range implied by the product name (girls teens 5–16). In that span, some children will care a lot about watch faces and games, while others may just want movement tracking. If your child isn’t interested in games or custom dials, the app-related extras may be less motivating.

Is it worth it?

Worth buying if you want a kids smartwatch that already covers the daily activity basics (steps, distance, calories and active minutes) and adds sleep tracking and heart rate, with IP68 waterproof protection for real-world messiness. It also suits families who like a bit of control over screen-time-style features, thanks to parent-restricted puzzle games.

Better avoided if you’re aiming for a highly feature-rich smartwatch experience beyond fitness and kids games, or if you don’t want to deal with phone/app compatibility at all (even though the watch can work without it, the “more functions” part is app-led). For most families wanting a practical, wear-it-every-day activity tracker with kid-friendly entertainment, it’s the kind of mid-range kids wearable that fits the brief—just don’t treat its health numbers as anything medical.
