JYUAJOI Fitness Tracker Smartwatch for Women Men, Silver 1.47" Curved Color Display, Continuous Heart Rate & SpO2 Monitor

The JYUAJOI Fitness Tracker is a full-featured wearable that continuously tracks heart rate and blood oxygen, monitors sleep, counts steps, and provides smart daily alerts on a bright 1.47" curved color display.

This lightweight smartwatch blends everyday activity tracking with wellness insights and convenient smart features. With continuous heart-rate and SpO2 monitoring, automatic sleep detection, 24+ sport modes, and water resistance, it’s built to handle workouts, swims, and daily life while syncing data to your phone app for historical review. Customizable watch faces, music controls, and notification alerts make it feel like a practical companion rather than a gadget.

How accurate is the continuous heart rate and blood oxygen monitoring?

The tracker uses optical sensors to collect near-real-time pulse and blood-oxygen data throughout the day. You can view live readings on the watch and review trends in the companion app to spot patterns over time.

• Continuous heart-rate readouts visible on-screen during activity and rest
• Automatic SpO2 sampling and on-demand blood oxygen checks
• Historical charts in the app help compare daily and weekly values

What sleep information will this smartwatch provide?

Sleep is tracked automatically—light, deep, and awake periods are identified so you gain a clearer picture of nightly rest. The device summarizes sleep duration and stages and offers simple suggestions to help improve sleep consistency.

• Auto-detection of sleep start, end, and stage changes
• Summary of total sleep time and stage breakdown each morning
• Personalized sleep insight tips accessible through the app

Which sports and daily features make it practical for workouts and routines?

Over two dozen built-in sport modes cover walking, running, cycling, swimming and more—each tracks steps, distance, calories, and heart rate in real time. The fitness tracker also includes everyday tools like call and message alerts, weather updates, and music control to keep you focused while training or working.

• 24+ exercise modes with live heart-rate and performance feedback
• IP68 rating for sweat and swim resistance during most water activities
• Smart conveniences: notifications, alarms, shutter control, and find-phone

How long does the battery last and which phones are compatible?

A 2-hour charge delivers roughly 5–7 days of typical use, depending on feature frequency such as continuous monitoring and screen brightness. It pairs via Bluetooth 5.0 with modern smartphones for seamless syncing and notifications.

• 5–7 days typical battery life after a 2-hour charge
