The RingConn is a smart ring that provides healthcare support just by wearing it on your finger.
I was surprised by the performance when I reviewed the RingConn Gen 2, but this time, I reviewed the RingConn Gen 2 Air, which allows you to start managing your health even more easily!
Reviewing the RingConn Gen 2 Air Smart Ring!

First, let's check the outer box.

An illustration of the contents was featured on the side.
Upon opening it...

The ring appears along with the words "AI Health for All"!
The RingConn Gen 2 Air is a lightweight and thin smart ring that supports daily health management by observing, recording, and analyzing your health status just by wearing it on your finger.
By wearing it on a finger, where capillaries are more densely packed than the wrist where smartwatches measure, high-precision health management is possible.
By using the RingConn Gen 2 Air, you can track the following information:
- Sleep duration
- Stress levels
- Activity
- Menstrual cycle
- Physical abnormality detection
- Heart rate
- Heart rate variability
- Blood oxygen
- Skin temperature
- Sedentary alerts
This includes items that are difficult to track on your own!
One thing to wonder about here is what exactly is the difference between the RingConn Gen 2 and the RingConn Gen 2 Air.
I have summarized the differences between the two designs.
| Spec Comparison | ||
|---|---|---|
| Product Name | RingConn Gen 2 | RingConn Gen 2 Air |
| Sleep Respiratory Monitoring | Available | None |
| Max Battery | 10–12 days (Charging Case) | 10 days (Charging Dock) |
| Material | Titanium Alloy | Stainless Steel |
| Weight | 2–3g | 2.5–4g |
| Price | 52,800 yen (tax included) | 34,800 yen (tax included) |
Although there are minor differences, the RingConn Gen 2 Air might be sufficient for people who do not snore much and do not take the device out for long periods.

The contents of the RingConn Gen 2 Air are as follows:
- RingConn Gen 2 Air smart ring
- Charging dock
- USB Type-C cable
- Instruction manual
- Quick start guide
A power adapter is not included, so please prepare one separately!

While the RingConn Gen 2 included a wireless charging case, the RingConn Gen 2 Air comes with a charging dock.
The size is compact and seems easy to carry around.

There are Variations: 2 in total for the ring colors: Galaxy Silver and Dune Gold.
This time, I chose Galaxy Silver!
The material is stainless steel, using a high-quality stainless material that is high in strength and rust-resistant.
It also features waterproof performance and can withstand sweat and water, making it perfect for daily use.
However, caution is required in hot and humid places such as saunas.

I lined it up with the RingConn Gen 2 in Matte Black.
Because it has a glossy presence, it gives the impression that it would also fit in well as a fashion item.
Since the width and thickness of the ring are the same as the RingConn Gen 2, I chose the same size 7.
Since it is US sizing, I recommend trying it on with the free sizing kit beforehand!

Place the ring on the charging dock to charge.
An incredible battery that can be used for 10 days with approximately 90 minutes of charging!
Since it is something you wear every day, it is very easy not needing frequent charging.
And essential is the integration with the smartphone app RingConn.
You can check the measurement results of various records within the app.
While some smart ring apps have monthly fees, RingConn surprisingly has free app usage fees!
It's also great that it's a one-time purchase model.
The dedicated RingConn app can be installed from the following:

Once installation is complete, pair with the ring!
Place it on the charging dock and turn on your phone's Bluetooth.
I was able to connect easily.

When actually wearing it, it feels natural and I hardly feel any weight.
Spending Time Wearing the RingConn Gen 2 Air
I lived for several days wearing the sparkling RingConn Gen 2 Air!
Let's look at the records I'm curious about!

When you open the app, you can see the overall results at a glance like this.
Since the score is out of 100 points, it's quite a good result, isn't it?
It is also possible to look at each item in detail.


In Sleep, it measures not only sleep time but also sleeping heart rate, skin temperature, and even REM and non-REM sleep in detail.
It visualizes your sleep quality in an easy-to-understand way.

In Activity, you can see steps and calories burned.
It also records exercises such as running and walking, so you can track how much you moved in a day.

There is also Stress, which is difficult to be aware of yourself.
This day was a holiday and I spent it relatively slowly, so there was almost no stress.
Looking at the graph, I could see that I felt more stress when out than when at home, and I was surprised by the accuracy.

For Vital Signs, the ring lit up periodically to measure heart rate and oxygen saturation.


There are also Menstrual Cycle Prediction and Pregnancy Planning Management for women.
In addition to cycle prediction from skin temperature measurements, there are also items where you can enter detailed information about physical condition and mood changes during menstruation.
Also, data sharing with a partner is possible, which is a welcome feature for those wishing to become pregnant.
