Smart Ring for Women Men, Health Fitness Ring Gen 3 with Free App No Subscription Fee, Stress & Sleep Monitor, Heart Rate & Step Tracker, IP68 Waterproof, Android/iOS Compatible (Gold,9)
Quick take
This smart ring is designed to track sleep, stress, heart rate, and blood oxygen while also handling everyday fitness like steps and distance. It uses a free mobile app (no monthly subscription fee stated) and is rated IP68 waterproof for showering and swimming. The biggest buying caveat is comfort and fit, so sizing matters, especially for side-sleeping and all-night wear.
Pros and cons
Pros
- No subscription fee for accessing the app insights is stated, which helps ongoing value.
- Sleep tracking includes sleep duration plus deep, light, REM, and wake time, with a readiness score.
- Fitness tracking covers steps, distance, calories and supports multiple sports modes (139+ stated).
- IP68 waterproof rating supports everyday wet-weather use.
Cons
- No built-in display means you must rely on the app for data and settings.
- Comfort and fit can be hit or miss for some wearers, including reports of finger irritation.
- Does not include GPS, so outdoor route tracking needs phone-based alternatives if you require it.
What buyers think
Buyer-review evidence points to a generally positive experience around day-to-day wearability and convenience. Multiple reviewers describe the ring as lightweight and comfortable for all-day tracking, with sleep and health metrics being the main reason people purchased it. Reviews also commonly highlight the value of having a free app experience without monthly subscription fees. At the same time, buyer feedback is limited, and there is at least one report of poor comfort that led the buyer to stop wearing the ring, so sizing and skin sensitivity are important considerations.
What this smart ring is for
The Smart Ring Gen 3 is aimed at people who want health and fitness insights from their ring instead of a watch or band. It’s especially relevant if sleep tracking is your priority, since it measures sleep duration and breaks it into common stages, plus wake times. If you also care about daily stress patterns and basic cardio-related signals, the built-in sensors are positioned to support that daily trend viewing.
Sleep and recovery tracking, explained
Sleep tracking focuses on the details most people actually use: total sleep time, deep sleep, light sleep, REM, and wake times. The ring also generates a readiness score intended to summarize sleep and recovery, helping you decide how to pace your day. Because it’s built for overnight wear, the design emphasizes a thin profile rather than a bulky sensor housing, which can matter for side sleepers.
Health and fitness metrics you get
For daytime and daily monitoring, the ring tracks heart rate and blood oxygen, plus stress level monitoring. On the movement side, it records steps, distance, and calories. It also supports 139+ sports modes (including categories like running, cycling, yoga, and swimming), and it can sync with the app over Bluetooth when you’re back within range.
Battery life and daily charging
Battery life is rated at about 3 to 5 days of active use, with standby up to about 5 to 7 days. Charging time is listed as around 1 hour. In practice, that means you can likely charge it on a regular routine, but the right cadence will depend on how frequently you use sports tracking and how long you wear it continuously.
Water resistance for real life
The ring is rated IP68 waterproof (waterproof for showers and swimming use is stated). That’s useful for people who don’t want to take a ring off frequently. If you plan to wear it during workouts or while washing up, the IP68 rating is a meaningful feature for everyday convenience.
Comfort and sizing are the make-or-break factor
This ring uses a sizing kit and notes that its sizing standard may differ from traditional jewelry ring sizing. It’s available in sizes 6 to 14, and the guidance recommends measuring finger circumference and using the sizing kit before ordering. Since smart rings sit directly on skin for long stretches, a poor fit can affect comfort and potentially sensor performance, so take sizing seriously.
Missing features to consider before you buy
Two limitations stand out for buyers who are used to more feature-rich wearables. First, there is no display, so you cannot glance at stats on the ring itself. Second, there is no GPS, so location-based metrics (like route mapping) will need to come from a phone or a GPS-capable wearable if that’s part of your routine.
Pros and cons recap
- Best for: People who want sleep-first smart ring tracking, daily stress and heart rate insights, step counting, and multi-sport modes without paying for a subscription to view the data.
- Who should buy: Side sleepers and people who dislike watches, plus anyone who prefers ring-style wearability and IP68 waterproof convenience.
- Who should avoid: If you need a ring with a screen, require GPS for outdoor tracking, or have had trouble with ring comfort or skin sensitivity to snug wearables.
How it compares to typical smart ring expectations
Compared with many smart rings in the category, this one aligns well with the “health and sleep first” use case. The no-subscription approach is a clear value lever, and the emphasis on sleep stages and readiness scoring matches what many shoppers look for when deciding between budget and brand-name options. If you mainly want workout accuracy with on-device feedback, the lack of GPS and the no-display design may push you toward an alternative wearable (like a watch) instead of a ring.
Price and availability
It’s currently listed with a price shown on the product page, and availability is indicated as in stock. If you want to compare value, focus less on the listed discount and more on fit (sizes 6 to 14), feature coverage (sleep stages, SpO2, steps, 139+ sports modes), and the no-monthly-fee app access.
Bottom line
The Smart Ring Gen 3 is a strong fit for buyers who want a lightweight, waterproof smart ring that tracks sleep stages, stress, heart rate, blood oxygen, and daily movement, with app access described as free of monthly subscription fees. Before purchasing, prioritize correct sizing and be mindful that comfort issues can happen with any ring that sits on skin overnight.
