In recent years, we have entered an era where it is not uncommon to manage your health using a smartphone or smartwatch.
In the midst of this, the RingConn Gen 2 smart ring has appeared to provide even easier healthcare support!
At first glance, it looks like a simple ring, but it is actually a reliable item that provides solid support for everything from signs of sleep apnea, heart rate, and blood oxygen monitoring to women's health.
I'll be reviewing how it actually feels to wear and use!
Reviewing the RingConn Gen 2 Smart Ring!

To actually wear it and measure accurate data, you want a size that fits you perfectly, but you might not know your finger size.
At RingConn, you can order a free sizing kit from the RingConn Official Website.
Before ordering the RingConn Gen 2, first check your ring size.

Opening it up immediately, I found rings ranging from size 6 to 14 and an instruction manual.
According to the manual, the index, middle, or ring finger of your non-dominant hand is recommended.
I tested with my index finger because the arterial blood flow is generally stronger there, which improves measurement accuracy.
Based on the size chart on the website, I predicted my index finger size to be 11, but when I tried them on, it was too large, and size 7 was just right.
Since it differs from your usual ring size and is something you wear 24 hours a day, I recommend trying them on before purchasing!

The manual is written in English, German, French, Spanish, Japanese, Italian, and Chinese, showing RingConn's global expansion.
Materials that realistically show the product colors, which are hard to choose through a monitor, are also included.
Since it's something you actually wear, it's nice to be able to see which color suits your skin.
The RingConn Gen 2 comes in four Designs: Future Silver, Matte Black, Rose Gold, and Royal Gold in total.
This time, I chose the Matte Black in size 7.

Excitedly opening it...

The inside of the RingConn Gen 2 has a precise structure that you wouldn't imagine from its 2.0mm thickness!
Since this is the part used for measurement, you wear it with this side facing the palm side of your finger.

It fits perfectly, just like the size I tried with the confirmation kit.

The charger is compact and is the type that snaps open.
It looks similar to a typical ring case.

The port is Type C, and you can charge it using the included USB cord.
The battery was low upon arrival, so I started by charging the RingConn Gen 2 before use!

According to the official info, a full charge takes about 90 minutes, and the battery lasts about 10 days!

Once charging was complete, the next step was syncing with the smartphone app.
The RingConn Gen 2 records measurement results by using the dedicated RingConn app.
While some smart ring apps have monthly fees, the RingConn Gen 2 app usage fee is free!
Since it's an item you use continuously, this is economically helpful.
The RingConn app can be installed from the App Store and Google Play.

Connection between the RingConn Gen 2 and the app via Bluetooth is complete.

I tried the heart rate measurement within the app.
After resting for about 1 minute while wearing the RingConn Gen 2...

I was able to easily measure a result of 60 beats per minute.

You can also perform blood oxygen measurements.
It's reassuring to be able to measure immediately whenever you're concerned.
So, what kind of results are recorded when actually living with the RingConn Gen 2 on?
I Spent 3 Days Wearing the RingConn Gen 2!
I spent three days living with the RingConn Gen 2 on.
It was so light that I forgot I was wearing it, and even as someone who doesn't usually wear accessories, I could use it without any discomfort.
The Matte Black is subtle and blended naturally into my fashion, which was great.
Regarding the waterproof function, daily hand washing was no problem, but please note that it cannot be used in saunas or while swimming in the ocean.
Now that I've measured for three days, let's look at the results in the app!

This is a graph that provides a comprehensive evaluation of your daily Wellness Balance.
It's a 100-point scale, and the higher the score, the better the trend.


Since it was a day off, I was warned because I lacked exercise and decided to sleep for a total of 11 hours...
Looking at this, I realized that the stiffness in my neck and back might be due to long hours of sleep.
Everything is measured accurately, so you can't keep secrets from the RingConn Gen 2.

There's also a detailed analysis of sleep.
You can even see the ratio of REM sleep to non-REM sleep.

The Sleep Breathing Monitoring is the biggest feature of the RingConn Gen 2.
After measuring sleep three times, it creates a Sleep Breathing Comprehensive Evaluation Report and records whether there is a possibility of sleep apnea syndrome.
This is an essential feature for people troubled by snoring.
The result showed no apnea abnormalities, which was a relief.
It's hard to notice these things on your own, so having it turned into data like this is helpful.

I was surprised when the green light occasionally flashed while wearing it, but it seems it was automatically measuring heart rate and blood oxygen periodically.
You can check your daily vitals on a graph.

Also checking stress levels.
I received a kind comment saying I was having a calm and happy day all day long.

Although this was a short-term use, there is also an item called Customized Plan where you can aim for an ideal healthy life under the support of the RingConn Gen 2.

After 3 days of use, the remaining battery was 78%!
The display by date and time is easy to understand, and it lasts a long time.
You can take it on trips or business trips with peace of mind.
Since you can share information with family and friends, it's also a perfect gift for someone concerned about their health.
