Frequently Asked Questions
Which finger is recommended for wearing the RingConn Gen 2 Smart Ring?
For optimal performance and accuracy, we recommend wearing the RingConn Gen 2 on the index finger. This finger typically has stronger arterial blood flow, enhancing measurement precision. However, the ring maintains consistent accuracy whether worn on the index, middle, or ring finger.
How to Determine Your RingConn Ring Size? What If You’re Between Sizes?
Please refer to the tips below:
1. Wearing the ring properly
The sensor inside your ring should be on the palm side of your finger. The ring should fit securely and comfortably around your finger's base.
2. Evaluate the fit
1.) Make sure your fingers are within average body temperature. Your fingers expand and contract based on environmental factors.
2.) We recommend wearing your sizing ring for at least 24 hours to confirm the best fit. (Your ring should not rotate as you perform regular daily tasks.)
3.) Wear it throughout the night. Your finger may be slightly larger in the morning.
4.) Choose the proper knuckle for your ring. A ring that is too tight or too loose is not suitable for accurate data measurement.
3. How to determine between the two sizes
We recommend choosing the smaller size in between to get more accurate measurements, or sending pictures and videos to us to assist you in choosing the best-fit size.
How long can the battery last?
The RingConn Gen 2 lasts up to 10–12 days on a full charge, depending on ring size:
Sizes 6–7: up to 10 days
Sizes 8–11: up to 11 days
Sizes 12–14: up to 12 days
Note: Enabling the OSA feature may increase power consumption due to more frequent monitoring.
How does RingConn protect my data?
RingConn takes your data privacy seriously. All data transmission, storage, and analysis are fully encrypted and processed on AWS servers located in the UK. For full details, please refer to our privacy policy here:
https://gb.h5.gdjztech.com/ringconn/h5/index.html#
How do I transfer data when switching to a new RingConn Gen 2?
Each RingConn account supports pairing with only one ring at a time. To retain your historical and future data in the same account, please unpair your old ring before pairing the new one.
Alternatively, you can create a separate account for the new ring. To avoid potential data loss from frequent account switching, we strongly recommend using separate devices for daily login and data sync (e.g., a different phone or tablet).
Is the RingConn Gen 2 capable of continuously monitoring my health?
Yes. It continuously monitors your heart rate, blood oxygen levels (SpO₂), body temperature, sleep, daily steps, calories burned during exercise, and more.
Can the RingConn Gen 2 monitor naps?
Absolutely. Whether you're sleeping overnight or taking a quick nap, the RingConn Gen 2 tracks your sleep patterns, including sleep apnea detection. It accurately measures your time in REM, Light, and Deep sleep stages, and detects breathing interruptions that may indicate sleep apnea. It also continuously tracks blood oxygen saturation (SpO₂) — a key metric many wearables overlook.
Can I wear the RingConn Gen 2 during workouts?
Yes. The RingConn Gen 2 is made of lightweight and durable titanium, making it ideal for activities like running, cycling, and yoga. It’s rated IP68 waterproof, so it can withstand sweat and water exposure.Note: Like many materials, it may scratch if it comes into contact with surfaces harder than the ring itself.
Is the Trade-In Program Applicable to Gen 2?
Currently, the trade-in program for Gen 2 is not supported. Please contact our CS team for more details.
Does the Order Include a Charging Case/Dock? What Is the Difference Between a Charging Case and a Charging Dock?
The Charging Case included in your Gen 2 order is specially designed for your ring size, allowing convenient wireless charging anytime, anywhere. Please note that the charging case is not available for separate purchases. In case of loss, kindly consider purchasing a replacement charging dock.
The Charging Dock included with your Gen 2 Air order is compatible with all ring sizes and supports wired charging. If you do not require another charging dock, there is no need for an extra purchase.
Is it Possible to Modify the Color Before Submitting the Order Information?
Only applicable to orders that select the "Don't know my size" option. After measuring the ring size with the sizing kit, you will have a one-time opportunity to update the ring color while submitting the ring details through your account.
