Chendssfkd Smart Ring — Health Tracker Ring with Heart Rate

This sleek white smart ring blends durable materials with everyday functionality so you can continuously track activity and sleep while keeping charging and data simple. Designed for both men and women, it pairs with the "Da Rings" app on iPhone and Android to display trends, sleep quality scores and daily activity summaries. The ring ships with a portable charging case and USB cable and offers multi-day battery life, plus a one-year warranty for support.

How accurate is the Chendssfkd Smart Ring for daily health and activity tracking?

The ring uses multi-sensor optical technology to capture heart rate, blood oxygen (SpO2) and heart rate variability along with motion-based step counting. It provides continuous monitoring to build trend data rather than single isolated readings. While useful for lifestyle insights, it is not a medical diagnostic device.

• Continuous heart rate and HRV monitoring for trend analysis
• SpO2 tracking during rest and sleep for overnight trends
• Automatic step counting and calorie estimates from motion sensors
• Not intended to replace professional medical equipment

What does the ring reveal about sleep and recovery?

The Chendssfkd ring breaks sleep into stages—deep, light and REM—and calculates a sleep quality score to help you understand nightly recovery. Weekly trend charts in the app highlight patterns so you can spot consistent issues. Use the insights to adjust bedtime routines and daytime habits.

• Detailed nightly breakdown: deep, light and REM durations
• Sleep quality score and weekly trend graphs in the app
• Automatic sleep detection—no manual input required
• Helps optimize rest routines through comparative data

What materials, water resistance and battery life can I expect?

Constructed from epoxy resin and stainless steel, the ring resists everyday scratches while remaining lightweight. It carries an IP68 rating, allowing use in showers and around water, and runs multiple days between charges depending on usage. Charging is flexible with both the included portable case and a USB charging cable.

• Durable epoxy resin and stainless steel construction
• IP68 water resistance for daily splash and shower protection
• 3–5 days typical continuous use per charge; longer standby
• Portable charging case plus USB charging cable included

How do I choose the correct ring size and set it up with my phone?

For best fit, measure using the Chendssfkd Size Measuring Kit or use a paper strip method to capture both the finger base and knuckle circumference. Install the free "Da Rings" app on Android 5.1+/iOS 8.0+ to pair, sync data, and review charts—no subscription required.

• Use the recommended size kit or paper-strip measuring method
• Compare larger of base/knuckle measurements to sizing chart
• Pair with "Da Rings" app for setup and continuous syncing
• Lifetime app access included, no monthly fees

Who is this ring for? The Chendssfkd Smart Ring suits active adults and busy professionals who want continuous lifestyle and sleep insights in a low-profile wearable. It appeals to people who prefer a discreet alternative to wrist wear, value water resistance and multi-day battery life, and want lifetime app access without recurring charges. It is ideal for users who prioritize trend tracking and convenience rather than clinical-grade measurements.
