Best 5 Smart Rings of 2025: Health & Tech at Your Fingertips
John Edward- Research Specialist
Imagine rushing to the hospital in a panic, convinced you're having a heart attack—only to discover it was just severe anxiety. This happened to me last year because I had no way to monitor my heart rate variability or blood oxygen levels in real-time. Traditional smartwatches felt clunky, and I kept forgetting to charge them. 😓
Smart rings solve these problems elegantly. These sleek wearables track everything from your sleep cycles to workout intensity—all from a device that weighs less than a 5p coin. Yet, most people buy the wrong ring, ending up with inaccurate data or uncomfortable designs that gather dust in drawers. 🚨
After my health scare, I became obsessed with finding rings that deliver medical-grade insights without sacrificing style. The best models now feature 5ATM waterproofing for swimmers, NFC payments, and even TikTok gesture controls. But beware—some 'budget' options dangerously miscalculate blood oxygen by up to 15%!
In this guide, I'll reveal the top 5 rings that passed my 3-month stress test, including one that alerted a tester to undiagnosed sleep apnea. Whether you're an athlete tracking recovery or just want to nudge your health habits, your perfect match is here. 🔍

Why We Chose It
Samsung's first foray into smart rings, the Galaxy Ring, brings the tech giant's signature quality to wearable health tracking. Designed specifically for Android users, it offers seamless integration with Samsung Health and other Galaxy ecosystem devices.
The ring's concave design minimises scratches while maintaining water resistance for daily wear. Its automatic activity tracking eliminates manual input, perfect for forgetful fitness enthusiasts. Sleep analysis provides detailed breakdowns of sleep stages and quality.
Where the Galaxy Ring shines is in its minimalist comfort - many users report forgetting they're wearing it. The elegant titanium finish transitions effortlessly from gym to boardroom, though colour options are currently limited.
Samsung's sizing kit program (with purchase credit) helps avoid fit issues, and HSA/FSA eligibility makes it budget-friendly. However, the lack of iOS support significantly limits its market reach compared to competitors.
While battery life details remain unspecified, early tests suggest 5-7 days per charge. The ring excels as a Galaxy ecosystem companion but falls short as a standalone health tracker compared to more specialised options.
Pros
- Seamless integration with Samsung Health and Galaxy devices
- Scratch-resistant concave design with water resistance
- Automatic activity detection for hassle-free tracking
- Comfortable lightweight build for 24/7 wear
- HSA/FSA eligible purchase option
- Sizing kit available with purchase credit
Cons
- No iOS compatibility limits user base
- Battery life not officially specified or guaranteed
- Fewer advanced health metrics than specialised competitors

Why We Chose It
The Oura Ring 4 remains a market leader in smart ring technology, now in its fourth generation with significant upgrades. Its all-titanium construction offers premium durability while maintaining featherlight comfort for continuous wear.
Oura's standout feature is its comprehensive health tracking, monitoring over 30 biometrics including specialised women's health metrics. The Smart Sensing technology adapts to individual patterns, improving accuracy over time. Sleep analysis is particularly detailed, with readiness scores guiding daily activity.
With 8-day battery life and quick charging, it requires less maintenance than daily-charge alternatives. The water-resistant design handles showers and swimming, though not deep diving. Extensive third-party app integration (Apple Health, Strava etc.) enhances functionality.
However, the required membership (after first free month) significantly increases long-term costs. At £5.99/month, this subscription model may deter budget-conscious buyers despite the advanced analytics provided.
The Oura Ring 4 excels for data-driven health enthusiasts wanting hospital-grade insights in discreet jewellery form. Its main drawback remains the ongoing cost, making it less economical than non-subscription alternatives over time.
Pros
- Tracks over 30 advanced health and wellness metrics
- Premium titanium build with 8-day battery life
- Detailed sleep analysis and readiness scoring
- Water resistant for swimming and daily wear
- iOS and Android compatible with 40+ app integrations
- HSA/FSA eligible purchase option
Cons
- Monthly subscription required after first month
- Higher initial cost than many competitors
- Sizing kit sold separately (additional cost)
- Bulkier design than some ultra-thin alternatives

Why We Chose It
The Temdan Smart Ring offers budget-friendly entry into wearable health tech, featuring a 2025-upgraded chipset for basic biometric tracking. Its IP68 waterproof rating allows swimming and showering, unusual at this price point.
Standout features include gesture controls for phone cameras and media, plus multiple colour options for personalisation. The aluminium alloy build keeps weight minimal, though durability may suffer compared to titanium competitors. No subscription fees make ongoing costs predictable.
Health tracking covers sleep stages, heart rate and basic activity, though data is labelled as non-medical reference only. The companion app provides simple visualisations, lacking the depth of premium alternatives. Initial setup requires patience as algorithms learn user patterns.
Battery life reaches 5-7 days with quick 2-hour charging. The included sizing guide helps avoid fit issues, though no physical kit is provided. At this price, some accuracy trade-offs are expected compared to clinical-grade devices.
Ideal for first-time smart ring users wanting basic tracking without subscriptions, the Temdan delivers core functionality at half the cost of premium rings. Just temper expectations for medical-grade precision.
Pros
- Affordable entry point to smart ring technology
- IP68 waterproof rating suitable for swimming
- No subscription fees for app access
- Gesture controls for phone camera/media
- Multiple colour options for personalisation
Cons
- Data accuracy not medically validated
