The 9 Best Smart Rings of 2024: Expert-Tested for Health, Battery Life, and Style
By Linda Park, Technology Editor
Last updated: June 2024 | See current deals
Smartwatches may dominate the wearable tech market, but for those who prioritize discretion, comfort, and seamless health tracking, smart rings offer a compelling alternative. Unlike bulky smartwatches, these sleek devices—worn like traditional rings—monitor heart rate, sleep, stress, and even body temperature without encumbering your wrist. After rigorously testing nine models over 30+ days, our team of experts (including marathon runners and bioengineers) has identified the best smart rings for every need—from elite athletes to beginners, and from budget-conscious buyers to those willing to invest in premium features like ECG sensors.
Key findings from our tests:
- The Oura Ring 5 remains the gold standard for accuracy and sleep insights, though its subscription model adds long-term costs.
- The Samsung Galaxy Ring is the top subscription-free option, with seamless integration for Galaxy Watch users.
- Budget pick RingConn Gen 2 Air delivers 7+ days of battery life for under $200—no subscription required.
- Only the Circular Ring 2 includes an FDA-cleared ECG sensor, making it ideal for heart health monitoring.
Why Smart Rings Are Worth the Hype (and the Trade-Offs)
Smart rings excel in three critical areas where smartwatches fall short:
1. Discreet Health Tracking
Unlike smartwatches that announce notifications with buzzes and vibrations, smart rings operate silently. They’re ideal for:
- Professionals who want to avoid distractions during meetings or presentations.
- Athletes who prefer not to wear a wristband during workouts (e.g., weightlifting, swimming).
- Night owls who need uninterrupted sleep tracking without a glowing screen.
2. Superior Comfort for 24/7 Wear
Our tests confirmed that smart rings are the most comfortable wearables for long-term use. The Oura Ring 5 and Ultrahuman Ring Air were worn continuously for 14+ days without irritation—unlike smartwatches, which often require breaks due to bulk or straps.
3. Longer Battery Life
While smartwatches typically need daily charging, the top smart rings last 5–12 days between charges. The RingConn Gen 2 even includes a charging case that extends battery life to 15–20 recharges, making it ideal for travelers.
The Downsides to Consider
No technology is perfect. Here’s what to weigh before buying:
- No screen or app interaction: Unlike smartwatches, you can’t dismiss notifications or check messages directly. All data lives in a companion app.
- Limited workout tracking: Most rings struggle with high-intensity exercises (e.g., HIIT, weightlifting) due to sensor placement. Pairing with a chest strap or smartwatch is often necessary.
- Subscription costs: Oura and Circular require paid plans ($6–$12/month) for full features, while Samsung and RingConn offer lifetime access.
- Durability concerns: Scratches are common on titanium models (e.g., Oura Ring 4), though the Ceramic Edition resists damage better.
How We Tested These Smart Rings
Our evaluation process goes beyond manufacturer specs. For each model, we:

- Wore it continuously for 7–14 days, including during sleep, workouts, and daily activities.
- Validated accuracy against medical-grade devices (e.g., chest straps for heart rate, polysomnography for sleep).
- Tested battery life in real-world conditions (e.g., charging only when <10% remaining).
- Assessed comfort with users of all finger sizes (we used sizing kits from Oura, Samsung, and RingConn).
- Evaluated companion apps for data presentation, alerts, and integration with third-party platforms (e.g., Apple Health, Google Fit).

Samsung’s Galaxy Ring 2 Delayed Until 2027
Fans of the Galaxy Ring will have to wait until 2027 for a successor, according to Samsung’s internal roadmap. While surprising (given the two-year refresh cycle for wearables), the delay ensures deeper integration with upcoming Galaxy Watch models.
Why it matters: If you’re in the Samsung ecosystem, the current Galaxy Ring remains the best subscription-free option until then.
Oura’s Removable Battery Patent: A Glimpse into the Future?
A patent filing reveals Oura’s plans for a removable battery in future rings, which could:
- Extend battery life further.
- Improve repairability and sustainability.
- Allow users to swap batteries mid-trip.

Smart Rings FAQ
1. What is the point of a smart ring?
Smart rings are discreet, sensor-packed wearables that track health metrics like:
- Heart rate and variability (HRV).
- Sleep stages (REM, deep, light).
- Body temperature (for ovulation/menstrual tracking).
- Steps, calories burned, and activity levels.
- Stress and readiness scores.
Unlike smartwatches, they free up your wrist for traditional watches or improve accuracy when paired with a smartwatch (e.g., Samsung’s Galaxy Ring extends battery life by up to 30%).
2. Is a smart ring worth it?
It depends on your priorities:
- Yes, if: You hate wearing a watch, prioritize sleep/health tracking, or want a lightweight alternative to smartwatches.
- No, if: You need NFC payments, app notifications, or advanced workout tracking (smartwatches are better for these).
Cost Comparison: Most smart rings ($200–$400) cost more than budget smartwatches but last longer on a single charge.
3. What are the disadvantages of smart rings?
Key limitations to consider:
- No screen or app interaction (all data is in a companion app).
- Limited workout tracking (best paired with a chest strap or smartwatch).
- Subscription costs (Oura and Circular require paid plans).
- Durability concerns (scratches on titanium models).
- No NFC (unlike smartwatches, you can’t use them for contactless payments).
4. What finger should I wear a smart ring on?
Most brands recommend:
- Avoid the thumb (less accurate sensor contact).
- Use your non-dominant index finger for:
- Best tracking accuracy.
- Avoiding interference with wedding rings.
- Compatibility with pinch gestures (e.g., Samsung Galaxy Ring).
How to Save on a Smart Ring
Smart rings are still a niche market, so deals are rare. Here’s how to get the best price:
- Shop during sales events: Black Friday, Amazon Prime Day, and holiday sales often include discounts (e.g., Oura Ring 4 dropped to $244 in 2023).
- Use price trackers: Our real-time price comparison tool scans 24,000+ stores for the best deals.
- Consider alternatives: If cost is a concern, screenless fitness trackers like the Fitbit Air or Luna Band offer similar discreet tracking for less.
- Spread the cost: Services like Raylo let you pay monthly for high-end rings.

—– WRITING INSTRUCTIONS — STYLE & OPTIMIZATION (apply ALL of these to the article you write; they are guidance for HOW to write, they are NOT article content — never copy, quote, restate, or output any of this text, its headers, or the words “MODE”/”DIRECTIVE”) —–
SEO MODE — Optimize for search without keyword-stuffing. Lead the first 100 words with the primary entity plus the news hook a reader would actually search for. Use clear, specific H2s phrased as the questions readers ask (“Why…”, “What happens next…”, “How…”). Front-load the answer in each section. Name concrete entities, figures, and dates — they drive relevance and featured snippets. Use the head term naturally a few times; never repeat it mechanically.
GEO MODE — Optimize to be quoted by AI answer engines (Google AI Overviews, Perplexity, ChatGPT). Open with a 40–60 word self-contained answer block as the lede: a complete, attributable mini-answer that stands on its own. Make every H2 section independently citable — a reader (or an AI) landing on just that section still gets a complete, sourced fact. State claims plainly with attribution (“according to [source]”). Prefer concrete, liftable sentences over vague framing.
INFORMATION-GAIN MODE — Add value the source articles don’t already state the same way. Include at least three of: a comparison between two sources’ figures, a “why it matters” tied to a NAMED precedent, a consequence a reader would ask about next, or a contrast in how outlets frame the story. CRITICAL: every added point must come from connecting the VERIFIED sources — never invent a fact, number, name, or quote to manufacture depth. If the sources don’t support more, stay shorter rather than pad.
HUMAN MODE — Write so it doesn’t read like AI. Vary sentence length sharply (mix 5–8 word sentences with 20–25 word ones). Use contractions. Anchor every paragraph with one concrete detail, number, or name. Banned phrases: “delve”, “in today’s fast-paced world”, “it’s worth noting”, “furthermore”, “moreover”, “navigate the landscape”, “game-changer”, “pivotal”. Banned headings: “What It Means”, “Key Takeaways”, “In Conclusion”. Read each sentence aloud — if it sounds like a press release, rewrite it. NEVER use typos, invisible characters, or synonym-swap tricks; write genuinely well instead.
E-E-A-T MODE — Demonstrate Experience, Expertise, Authoritativeness, and Trust. Attribute every factual claim to a NAMED source (“according to [outlet/official/document]”). Anchor the story in time with explicit dates. Where the sources show first-hand reporting, on-the-ground detail, or official records, foreground it. Distinguish what is confirmed vs. reported vs. alleged. No anonymous “experts say” or “studies show” without a named source from the material. Trust is built on verifiable attribution — NEVER on invented credentials, sources, or affiliations.
COMPARISON MODE — When the sources support it, frame the story comparatively: put competing figures side by side, contrast how different outlets characterize the same event, or set this development against a clearly-sourced prior one. A short compare-and-contrast passage (or a small table only if the data is clean) lets the reader see the differences at a glance. GUARDRAIL: compare ONLY facts present in the sources — never fabricate a data point, a second party, or a prior event to manufacture a contrast. If there is nothing real to compare, don’t force it.
FACT-LOCK — CRITICAL, this overrides every other instruction including length, structure, and persona. Do NOT invent people, organizations, job titles, roles, affiliations, statistics, dates, studies, awards, or quotes. NEVER attribute a quote, statement, comment, or reaction to a named expert, lawyer, solicitor, spokesperson, official, doctor, analyst, psychologist, professor, or representative of any company, firm, university, or institution unless that exact person AND that exact statement appear in the provided source material. If you have no real, sourced named authority for a reaction or expert opinion, OMIT it entirely — do not manufacture an authority, a firm, or a quote to add credibility, drama, or color. Entertainment, soap-opera, spoiler, celebrity, lifestyle, sports, and feature articles must contain NO invented legal, medical, financial, or professional commentary whatsoever. DEPTH FROM REAL SOURCES: aim for a full, detailed, comprehensive article — use ALL of the relevant facts, names, figures, quotes, context, and background that actually appear across the provided source material and the related/web-search articles. The more REAL sourced detail is available, the longer and more thorough the article should be; do not artificially shorten when the sources genuinely support more. But build every bit of that length and depth from material that is actually IN the sources. NEVER invent a name, quote, statistic, study, expert, affiliation, or detail to reach a length, fill a section, or add authority — if the sources do not support more, write what is supported accurately rather than padding with anything invented. A long article fully backed by real sources is the goal; a long article containing even one invented name, firm, number, or quote is a FAILURE. When unsure whether a name, organization, or quote is real, leave it out.
