It tracks sleep and heart rate reliably, with especially useful sleep insights. Battery life lasts several days, which is very convenient. The app is simple and clear, though it could offer more advanced features. Overall, it’s a great value for basic health tracking in a discreet design. Review: I LOVE this ring! - I’ve been wearing this tracking ring for 5 months now, nonstop, & I LOVE IT. I really just wanted to track my sleep, my activity, & my stress throughout the day, plus I wanted to make sure I didn’t have an apnea issue. Comfort wise, RingConn is thinner than the Oura ring, & less annoying feeling (to me) than wearing an Apple watch. I get very rashy from wearing anything with nickel content - a previous Apple watch & band clasp made me rashy even. So one of the things I was concerned about was the nickel content. I’m happy to report that I have zero sensitivity or rashy response. Looks wise, I love that silicone covers in many colors are cheap to buy. It does say it’s water resistant, but I err on the side of caution & don’t soak it in water or shower with it on. But the best part: the function! This ring (with only the free app, no extra paid plan required), gave me an apnea test over multiple nights & ruled out any issues. It maps out my REM, deep sleep, light sleep, & activity every night & gives me a sleep score & total sleep time. RingConn tracks my stress & alerts me when my stress levels spike. It does take about 30-ish mins for it to alert me, but its been very helpful for me to know. It also holds its charge for almost 2 weeks, & from a very low charge fully charges back up in a little over an hour. That is FAR less frequent charging than an Apple watch needs. The most interesting thing: one day RingConn told me I had a headache COMING ON. I was confused bc I felt nothing. For 3 days, it showed this warning. Since I had only worn it for a month at the time, I thought I got a malfunctioning ring. BUT then! On the 4th day, I woke up sick! So RingConn literally warned me that I was getting sick (& was possibly contagious) before I even felt any symptom at all. I am super aware of my body, so this was amazing to me. That was the only time I have been sick since I’ve worn RingConn so I’ll be interested to see if it warns me similarly the next time I get sick. I took a chance on RingConn during black Friday, so I got a great deal on it. Even at full price, I would highly recommend this. I love mine! ## Features - [Size Before You Buy] Before purchasing the RingConn Smart Ring, we highly recommend acquiring the RingConn Sizing Kit to determine the most comfortable and suitable size for your finger. Please note that the RingConn Sizing Kit is only compatible with the RingConn Smart Ring - [Not Standard Sizing] RingConn Smart Ring differs from standard rings as it contains sensors on the inside. Therefore, we recommend using the RingConn Sizing Kit to determine the best fit. The RingConn Smart Ring is available in sizes 6 to 14, accommodating various finger sizes - [How to Measure & Fit Check] Wear the sizing gauge snugly around the base of your finger, ensuring it doesn’t rotate freely. We recommend wearing it for over 24 hours to determine your most accurate fit. For optimal data and comfort, the RingConn Smart Ring should fit snugly against your skin without rotating. When testing for the best size, make sure the sizing gauge remains tight around the base of your finger - [Choose a Finger] The RingConn Smart Ring can be worn on any finger and on either hand. For optimal accuracy and comfort, we recommend wearing the RingConn Smart Ring on your index, middle, or ring finger. Be sure to size the exact finger on which you plan to wear your RingConn Smart Ring for the best fit - [Manufacturing Quality] RingConn Sizing Kit is made from premium-grade plastic, while the RingConn Smart Ring is crafted from aerospace-grade titanium, coated with a scratch-resistant layer for outstanding corrosion resistance and durability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DGFZ3VWP | | Age Range Description | Adult | | Best Sellers Rank | #187 in Electronics ( See Top 100 in Electronics ) #2 in Smart Rings | | Brand Name | RingConn | | Color | White | | Customer Reviews | 4.2 out of 5 stars 5,821 Reviews | | Included Components | Instruction Manual, RingConn Sizing Kit | | Manufacturer | Guangdong Jiu Zhi Technology Co., Ltd. | | Material | Plastic | | UPC | 810180160926 | ## Product Details - **Brand:** RingConn - **Color:** Sizing Kit - **Connectivity Technology:** Bluetooth - **GPS:** No GPS - **Model Name:** RingConn Gen 2 Sizing Kit - **Operating System:** RingConn Smart Ring - **Shape:** Round - **Special Feature:** Activity Tracker, Heart Rate Monitor - **Target Audience:** Unisex Adults - **Wireless Communication Standard:** Bluetooth ## Images ![RingConn Gen 2 Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Image 1](https://m.media-amazon.com/images/I/51k2gRPBrAL.jpg) ![RingConn Gen 2 Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Image 2](https://m.media-amazon.com/images/I/61yh28IbqLL.jpg) ![RingConn Gen 2 Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Image 3](https://m.media-amazon.com/images/I/61I4Ry3rrhL.jpg) ![RingConn Gen 2 Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Image 4](https://m.media-amazon.com/images/I/71gOWTPiQaL.jpg) ![RingConn Gen 2 Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Image 5](https://m.media-amazon.com/images/I/61JClSANEBL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Calidad y precio *by A***S on April 26, 2026* The RingConn smart ring is lightweight, comfortable, and easy to wear all day.

As someone managing sleep apnea, the level of detail this ring provides is incredible. It tracks my AHI (Apnea-Hypopnea Index) and blood oxygen levels throughout the night, which gives me peace of mind and real data I can actually use to monitor my health. What I love: • Sleep Tracking: The sleep apnea monitoring is top-notch. It even flagged a significant oxygen drop for me, which really helps in understanding my sleep quality. • Step Counting: It’s surprisingly accurate with steps. I’ve compared it to other trackers, and it holds its own perfectly. • Comfort: It's lightweight and comfortable enough to wear all day and night without irritation. The Trade-off: The only thing to keep in mind is the battery life. While it’s rated for longer, using it as a dedicated sleep apnea and oxygen tracker means the battery drains a bit faster—I usually get about 7 days out of it. Honestly, for the amount of vital data it’s pulling while I sleep, that’s a trade-off I’m more than happy to make. If you’re looking for a discreet, powerful way to track your health and sleep, I can’t recommend this enough! ## Frequently Bought Together - RingConn Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Find The Perfect Ring Size Smart Ring Size - Only Smart Ring - ULTRAHUMAN AIR-Smart Ring Health Tracker, Sleep & Fitness Tracker, Smart Ring for Men/Women, Size First Sizing Kit - Oura Ring 4 Sizing Kit - Size Before You Buy Oura Ring 4 - Unique Sizing - Receive Credit for Purchase --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/691271246-ringconn-gen-2-sizing-kit-size-first-before-you-buy](https://www.desertcart.ro/products/691271246-ringconn-gen-2-sizing-kit-size-first-before-you-buy) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-27*
