ZBNMY Health Smart Bracelet Fitness Tracker, Silver, Continuous Heart Rate and SpO2, IP68

This silver ZBNMY wristband combines continuous health sensors with activity tracking and smartphone connectivity for iOS and Android. It provides on-wrist readings and syncs data to a free companion app so you can review daily trends, map outdoor routes, and set goals without recurring fees. The device is built for everyday wear — sweat and splash resistant — and aims to help you track progress with over 120 exercise modes.

How accurate are the heart rate and blood oxygen readings?

The bracelet uses optical sensors to estimate heart rate and blood oxygen throughout the day and during workouts. While readings give useful trends and alerts, they are intended for general wellness tracking rather than clinical diagnosis.

• Continuous optical heart rate monitoring for resting and active periods
• Spot and trend SpO2 (blood oxygen) measurements
• On-device quick-checks with synced history in the companion app

Which activities and GPS features can I use while exercising?

ZBNMY supports a wide variety of sports modes — from walking and running to triathlon and rock climbing — plus specialized outdoor GPS modes. When you select an outdoor mode, the tracker records route data that can be viewed on the app map in real time or reviewed after your session.

• Over 120 exercise modes including swimming, yoga, and cycling
• Three GPS options optimized for walking, running and cycling
• Real-time route mapping and activity summaries in the app

What are the battery life and durability expectations?

The large-capacity battery and low-power design balance frequent use with long runtime: a 2-hour charge provides days of active tracking and extended standby. The IP68 rating protects against splashes, sweat and rain, making it suitable for daily wear and most water-exposed activities.

• 2 hours charging time for 15–30 days of regular use
• Approximately 45–60 days standby time
• IP68 waterproof rating for splash and sweat resistance

How does the companion app enhance the bracelet?

The ZBNMY app collects sensor data, displays trends, and lets you customize alerts and goals. Importantly, the developer guarantees the app is free with no subscription or hidden fees, so you can access your history and settings without ongoing costs.

• Syncs health metrics and sleep analysis to the app dashboard
• Customizable alarms, reminders and fitness rings for motivation
• Free app usage with no subscription or service charges

Who is this for: The ZBNMY Health Smart Bracelet is designed for people who want an affordable, all-in-one tracker to monitor daily activity, sleep patterns and basic vitals without subscription costs. It fits fitness enthusiasts who use multiple sport modes and outdoor routes, commuters who need long battery life, and anyone seeking a splash-proof wearable that integrates with iOS or Android.
