qiunhang Smart Bracelet fitness tracker for men & women — Black, 24/7 HR & HRV stress monitoring, 170+ sports modes

qiunhang Smart Bracelet is a minimalist, screenless fitness tracker that continuously monitors heart rate, HRV, sleep and stress while supporting 170+ sports modes and two interchangeable nylon bands.

This compact wearable pairs with the free QRing app to turn day-to-day movements into actionable trends: continuous heart-rate and HRV logging, advanced sleep-stage breakdowns, stress indicators, and a large activity library that covers everything from walking to swimming. Designed to be featherlight at 25 g with a curved body and two strap lengths, it prioritizes comfort so you can wear it all day and night without distraction.

How does the qiunhang Smart Bracelet keep track of my heart and stress levels?

The device uses continuous optical sensing to collect heart rate and HRV data around the clock, then uploads summaries to the QRing app for trend analysis. Stress estimates are derived from heart-rate variability patterns and presented as easy-to-read summaries so you can spot changes over days or weeks.

• 24/7 heart rate logging with HRV-derived stress indicators
• Automatic Bluetooth sync to QRing for graphing and export
• No subscription required to view full data within the app

What sleep insights will I get and how are naps handled?

Sleep tracking separates deep, light and awake periods for both overnight rest and short naps, offering an overview of nightly recovery and daytime sleep patterns. The app highlights duration and stage distribution so you can identify habits that affect sleep quality.

• Night and nap detection with stage classification
• Sleep-duration summaries and stage percentages in-app
• Trends over time to help evaluate routine changes

Can it support different workouts and daily convenience features?

Yes — the qiunhang Smart Bracelet includes over 170 sports modes to cover most activities from yoga to swimming, tracking steps, distance and calories for each session. It also offers smart utilities like call alerts and remote camera control to complement exercise tracking.

• 170+ activity profiles including water-friendly exercise modes
• Step, distance and calorie metrics for structured sessions
• Call notifications and remote shutter control for quick use

How long does the battery last and how durable is the design?

The tracker is optimized for long battery life: typical use stretches 45–60 days, with a conservative continuous-use window of 20–30 days depending on settings. The 1ATM protection rating safeguards against splashes, sweat and light rain while the lightweight, curved body and two band sizes ensure comfortable all-day wear.

• Up to 45–60 days on regular use, 20–30 days continuous in some modes
• 1ATM splash-resistant for daily moisture exposure
• 25 g curved body with two nylon straps for a tailored fit

Who this is for: The qiunhang Smart Bracelet suits anyone who prefers a subtle, minimalist tracker that prioritizes long battery life and continuous health signals without a large touchscreen. It’s ideal for active people who want detailed activity options and sleep analysis in a low-profile wearable, plus those who value a no-subscription app and simple smart features for daily convenience.
