Zeacool Fitness Tracker – 5ATM Water-Resistant Activity Band with HR, SpO2 & BP Monitor

The Zeacool Fitness Tracker is a budget-friendly wrist-worn activity band offering 24/7 heart-rate monitoring, blood oxygen (SpO2) tracking, blood pressure measurement, and sleep monitoring. It includes step counting, calorie tracking, and multiple workout modes. The device features a small AMOLED or LCD display, is rated 5 ATM water-resistant (suitable for swimming), and claims multi-day battery life. It connects via Bluetooth to iOS and Android apps for data sync and insights. No subscription is required for basic tracking. This is an entry-level tracker aimed at budget-conscious users seeking essential health metrics without premium pricing or ecosystem lock-in. Sensor accuracy and app polish are typical of the sub-$30 segment—functional but not lab-grade.
