10 Best Smart Rings 2025 in the United States

The Oura Ring 4 is a sleek and modern smart ring, designed primarily for health tracking, and offers several appealing features for users interested in monitoring their wellness. One of its standout strengths is its impressive battery life, lasting up to 8 days on a single charge. This means you won’t have to worry about recharging it frequently, making it convenient for daily wear.

In terms of health tracking capabilities, the Oura Ring 4 excels with features like heart rate monitoring and sleep tracking, which can be incredibly beneficial for those looking to improve their fitness and overall health. Its compatibility with Bluetooth allows it to connect easily to smartphones, enabling users to view their health data seamlessly through the associated app.

The design of the ring is another plus; it features a modern aesthetic that appeals to both men and women and is generally comfortable to wear throughout the day and night. Its water resistance adds to its durability, making it suitable for everyday activities. However, there are a few drawbacks to consider. Firstly, the lack of GPS means that it may not satisfy users who want to track outdoor activities more precisely. Also, while it has solid health tracking features, some users might find the data less detailed compared to larger fitness trackers or smartwatches. Additionally, the price point could be a concern for budget-conscious consumers, as it may not be the most affordable option in the market.

The RingConn Gen 2 Air is a sleek, ultra-thin smart ring designed to track various health metrics including sleep, heart rate, stress, blood oxygen, physical activity, and menstrual cycles. Its AI-powered insights provide personalized guidance to help improve your daily habits, which can be very helpful if you are focused on wellness. One standout feature is its comfort—it's very light and slim (only 2mm thick), so it’s easy to wear all day and night without feeling bulky or distracting. The battery life is quite impressive as well, offering up to 10 days of use on a single charge, which means less hassle with frequent recharging. Charging is also quick, taking about 90 minutes for a full charge. It’s compatible with both iOS and Android devices and doesn’t require any subscription fees for the essential features, making it budget-friendly in the long run. The ring is also highly durable and waterproof (IP68 rating), allowing you to wear it during daily activities, swimming, or even diving without worry. Additionally, the new “Find Your Ring” feature helps you locate the ring easily if misplaced, which is a thoughtful addition.

On the downside, there is no built-in GPS, so if you are looking for location tracking during workouts, this ring won’t cover that need. Also, the sizing system is unique, so you must use their sizing kit to ensure a proper fit, which might be a bit inconvenient compared to standard ring sizes. While it has a minimalist design perfect for those who want something subtle, some users might prefer more visual customization options. The RingConn Gen 2 Air represents a strong choice for anyone wanting continuous health tracking in a discreet, comfortable form factor with solid battery life and durability, especially if you’re not in need of GPS or extensive customization.

The RingConn Gen 2 is a smart ring designed to support health monitoring with a standout feature: sleep apnea tracking, which is uncommon in this category. It offers accurate sleep health insights backed by AI and research partnerships, making it a strong choice for those concerned about sleep quality. The ring tracks a broad range of health metrics including heart rate, stress, blood oxygen, and women's health, providing comprehensive data without ongoing subscription fees.

Battery life is impressive, lasting up to 12 days depending on the size, and the included charging case extends usage significantly. Compatibility is broad, working with both Android and iOS devices via Bluetooth, ensuring most users can connect easily. The design is ultra-thin and lightweight, improving comfort for continuous wear, and its water resistance up to 100 meters means it can handle swimming and everyday activities without worry. Sizing is carefully addressed through a unique sizing kit, helping avoid fit issues upfront, which is important for a wearable you’ll want to keep on all day. Additionally, it’s eligible for HSA/FSA purchases, a bonus for users wanting to use health funds.

On the downside, the lack of built-in GPS limits location tracking, and the operating system is relatively basic. While it supports OTA updates, the ring’s memory and storage are limited, so feature expansion might be gradual. Some users may find the initial sizing process a bit cumbersome compared to simpler rings. This smart ring is suited for users looking for a health-focused device with advanced sleep apnea monitoring, long battery life, and durable design but doesn’t cover location tracking or extensive app ecosystem features.
