Kids fitness tracker with AMOLED screen

The BIGGERFIVE KR05 is an activity tracker designed for children aged 5 to 15. It features a 0.95 inch AMOLED display and operates independently without requiring a smartphone connection. The lightweight band weighs 1.6 grams and offers up to 240 hours of battery life on a single charge.

Water resistant design and low power draw

With a 3ATM waterproof rating the device withstands swimming and daily splashes. The lithium-ion battery supports up to 10 days of typical use including continuous heart rate monitoring and sleep tracking. No active cooling is needed so the tracker runs silently on the wrist.

Sustained tracking across sport modes

The watch provides 10 sport modes for activities such as running, cycling and swimming. Sensors deliver continuous heart rate data and sleep stage analysis throughout extended sessions. Habit reminders, mini-games and a virtual pet keep children engaged during long-term daily wear.

Questions about this item

How do I set up the KR05 tracker for a child aged 5 to 15 without using a phone or app?

The KR05 operates independently; press the side button to wake the 0.95 inch AMOLED screen, then follow the on-screen prompts to enter the child's age, height and weight. No smartphone pairing is required for step counting, heart rate monitoring or the 10 sport modes.

What maintenance will the KR05 need after months of daily wear?

Recharge the lithium-ion battery every 240 hours using the supplied magnetic cable. Clean the 3ATM water-resistant case and strap with fresh water after swimming. The 1.6 gram module can be removed from the strap for thorough drying.

Which limit appears first during a long swim session with continuous heart-rate tracking?

The 3ATM water-resistance rating covers swimming, but continuous heart-rate monitoring and the vibrating alarm draw extra power, so the 240-hour battery life will be reached sooner than during basic step counting alone.
