Please note that the RingConn size set is only compatible with the RingConn smart ring. - No standard size: The RingConn Smart Ring is different from other rings because it contains sensors inside. We therefore recommend using the RingConn size set to determine the best fit. The RingConn smart ring is available in sizes 6 to 14 to adapt to different finger sizes. - Measuring and checking the fit: Place the gauge comfortably and easily around the base of your finger and make sure it does not rotate freely. We recommend using it for more than 24 hours to determine your setting as accurately as possible. For optimal data and comfort, the RingConn Smart Ring should lie perfectly on your skin without turning. When testing the appropriate size, make sure that the meter sits firmly on the finger. - Choose a finger: The RingConn smart ring can be worn on any finger or hand. For optimal precision and comfort, we recommend wearing the RingConn Smart Ring on your index finger, middle finger or ring finger. For the optimal fit, ensure that the finger you wish to wear your RingConn Smart-Ring on is measured precisely. - High Quality Construction: The RingConn sizing set is made from high-quality plastic, while the RingConn Smart Ring itself is made from titanium, which is used in the aerospace industry. In addition, it is coated with a scratch-resistant layer for excellent corrosion resistance and durability. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0F43QZV4X | | Age Range Description | Adult | | Band Material Type | Titanium | | Battery Average Life | 10 days | | Battery Cell Type | Lithium Polymer | | Best Sellers Rank | 1,728 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 382 in Wearable Technology (Electronics & Photo) | | Box Contents | RingConn Gen 2 Air Sizing Kit | | Brand Name | RingConn | | Case Material Type | Titanium | | Closure Type | Magnetic | | Colour | Ring Sizing Kit | | Communication Feature | Bluetooth | | Compatible Devices | Smartphone | | Compatible Phone Models | Android Devices, iOS Devices | | Connectivity Technology | Bluetooth | | Customer Reviews | 4.6 4.6 out of 5 stars (1,410) | | Display Type | No Display | | GPS Geotagging Functionality | No GPS | | Human Interface Input | Touchscreen | | Item Weight | 0.1 Kilograms | | Manufacturer | Shenzhen Ninenovo Technology Limited | | Memory Storage Capacity | 2 MB | | Metrics Measured | Heart Rate Monitor, Activity Tracker | | Model Name | RingConn Gen 2 Air Sizing Kit | | Model Number | RCA-02 | | Operating System | RingConn App | | Product Features | Activity Tracker, Custom Activity Tracking, Heart Rate Monitor, Multisport Tracker, Sleep Monitor | | Shape | Round | | Style Name | Minimalist | | Supported Application | Fitness Tracker, Heart Rate Monitor, Sleep Monitor | | Target Audience | Unisex Adults | | Warranty Type | Limited | | Water Resistance Depth | 100 Metres | | Water Resistance Level | Water Resistant | | Wearable Computer Type | Smart Ring | | Wireless Compability | Bluetooth | ## Product Details - **Battery cell composition:** Lithium Polymer - **Brand:** RingConn - **Connectivity technology:** Bluetooth - **GPS:** No GPS - **Memory storage capacity:** 2 MB - **Model name:** RingConn Gen 2 Air Sizing Kit - **Operating system:** RingConn App - **Shape:** Round - **Special feature:** Activity Tracker, Custom Activity Tracking, Heart Rate Monitor, Multisport Tracker, Sleep Monitor - **Wireless communication standard:** Bluetooth ## Images ![Smart Ring RingConn Gen 2 Air Sizing Kit - size First Before You Buy - Choose from 9 Sizes 6 to 14 - Image 1](https://m.media-amazon.com/images/I/51jD7WyOhwL.jpg) ![Smart Ring RingConn Gen 2 Air Sizing Kit - size First Before You Buy - Choose from 9 Sizes 6 to 14 - Image 2](https://m.media-amazon.com/images/I/61VkYwJxMBL.jpg) ![Smart Ring RingConn Gen 2 Air Sizing Kit - size First Before You Buy - Choose from 9 Sizes 6 to 14 - Image 3](https://m.media-amazon.com/images/I/61jqGHms3fL.jpg) ![Smart Ring RingConn Gen 2 Air Sizing Kit - size First Before You Buy - Choose from 9 Sizes 6 to 14 - Image 4](https://m.media-amazon.com/images/I/719GqhPaarL.jpg) ![Smart Ring RingConn Gen 2 Air Sizing Kit - size First Before You Buy - Choose from 9 Sizes 6 to 14 - Image 5](https://m.media-amazon.com/images/I/61CwGQHzYLL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - RingConn Gen 2 Air Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Only Smart Ring - ULTRAHUMAN Ring AIR-Smart Ring Health Tracker, Size First Sizing Kit,Sleep Tracker,Smart Ring for Men/Women,Fitness Tracker (Made in India, Swatch Sizing Kit, Swatch 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.co.uk/products/777611889-smart-ring-ringconn-gen-2-air-sizing-kit-size-first](https://www.desertcart.co.uk/products/777611889-smart-ring-ringconn-gen-2-air-sizing-kit-size-first) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
