YULUCKGO BJ02 Smart Ring Fitness Tracker: Continuous heart rate and blood oxygen tracking
For the active woman who juggles fitness goals with family life, this smart ring is your discreet health companion. It tracks your heart rate and sleep patterns while you manage daily routines, giving you a clear picture of your wellness without interrupting your day.

With up to 5 days of battery life and quick charging, it stays powered through busy weeks, and its IP68 waterproof design means you can wear it from morning showers to evening swims without a second thought.
