Luna Ring: The Black‑Friday Deal That Lets You Track Your Fitness (and Sleep) in a Tiny, Wearable Package

If you’ve ever wanted a discreet, ring‑shaped wearable that can give you the same data‑driven insight into your activity, sleep, and health that a smartwatch offers—without the bulk—then the Luna Ring is the gadget that’s been in the news this holiday season. CNET’s Black‑Friday “Deals” page highlighted the Luna Ring as one of the hottest tech steals of the year, slashing its price by a whopping 66 %. In this roundup, we’ll break down what the Luna Ring is, why it’s worth a closer look, and how the Black‑Friday discount makes it an even more compelling purchase.

What is the Luna Ring?

The Luna Ring is a compact, ring‑style fitness tracker developed by a startup that has quietly built a reputation for delivering “high‑quality, affordable wearables.” Unlike a smartwatch or a clip‑on fitness band, the Luna fits on your finger, making it a subtle way to stay connected to your data.

At its core, the Luna Ring monitors a suite of biometric data:

In addition to raw numbers, the ring’s companion app (available on iOS and Android) contextualizes data into “daily wellness scores” and offers coaching prompts that encourage you to stay on track with your goals.

The Black‑Friday Offer

CNET’s “Deals” page lists the Luna Ring at a 66 % discount from its usual price. The original price sits around $199 (though the exact figure varies by retailer), which means the Black‑Friday deal lands you a ring for roughly $65–$70. That level of savings—over two‑thirds off the retail price—is rare for a piece of wearable technology that delivers genuine health metrics.

The promotion is tied specifically to Black Friday, so timing matters. The discounted price is available for a limited period (usually the first week of November). Once the deal expires, the price jumps back up, so if you’ve had your eye on the Luna, this might be the perfect opportunity to make a purchase.

How to Buy

Getting the ring is straightforward. The article directs readers to the official Luna website and several authorized resellers. Here’s a quick play‑by‑play:

1. Navigate to the CNET “Deals” page – The article includes a prominent “Buy Now” button that takes you to a retailer’s site (often a major e‑commerce platform or a dedicated Luna storefront).
2. Select your size – The Luna comes in several sizes (typically ranging from 6–10 mm in circumference). You’ll need to choose the right fit, or you can use an adjustable band that comes with the ring.
3. Add to cart – The discount should automatically apply once you add the ring to your shopping basket. You’ll see a clear price breakdown: original price, discount, final price.
4. Check out – Proceed to checkout. Most retailers accept major credit cards, PayPal, and in some regions, Apple Pay or Google Pay.
5. Activate your subscription – While the ring itself is free of recurring costs, the Luna app offers a premium subscription that unlocks deeper analytics, personalized coaching, and advanced sleep diagnostics. The article mentions that the subscription can be set up during the initial setup process on the app.

Why the Luna Ring Stands Out

1. Compact, Comfortable Design

Because it sits on your finger, the Luna is less likely to interfere with daily activities—whether you’re typing, lifting weights, or doing household chores. The ring is made from a hypoallergenic alloy, making it suitable for most skin types.

2. Battery Life That Outpaces Most Rings

Many fitness rings require frequent charging (often every 2–3 days). The Luna claims a 7‑day battery life on a single charge—enough to last most people through a typical weekend or a full work week without needing to plug in. The ring also supports fast charging via a small docking station.

3. Robust Tracking

While the device’s sensors are small, they’re calibrated to provide a reasonable level of accuracy. For many casual users, the data is more than sufficient to keep track of their activity levels, sleep quality, and heart‑rate trends. The ring also offers a “fitness score” that updates daily, helping you spot patterns over time.

4. Privacy‑Friendly Approach

Some wearables—especially those that track heart‑rate and sleep—raise concerns about data privacy. Luna emphasizes that all sensitive data is stored locally on the device and encrypted when transmitted to the cloud. The app’s privacy policy states that it does not share personal health data with third parties without explicit user consent.

Competition & Comparisons

The article does a brief nod to the broader market of ring‑style wearables, mainly the Oura Ring and the Motiv Ring. Here’s a quick side‑by‑side snapshot:

The Luna’s biggest selling point remains its price—especially when slashed by two‑thirds. While the Oura and Motiv rings offer a few more advanced metrics and slightly more accurate algorithms (thanks to larger sensor arrays), the Luna is a highly competitive alternative for users who prioritize affordability without sacrificing the core functionality.

Practical Tips If You Buy

1. Let the Ring Charge Fully – A fully charged ring can often last a week; partial charges can shorten battery life. Once you get the ring, charge it for at least 12 hours before you start wearing it.
2. Sync Frequently – Even if you’re only using the free tier, syncing at least once a day ensures your data is updated. The app also calibrates your step count and distance based on your body weight and stride length.
3. Take Advantage of the App’s Coaching – The Luna app offers “quick insights” (e.g., “You slept 7 hours last night, but your sleep quality was 4/10 because you woken up twice”). These insights can help you adjust your habits (e.g., limit caffeine, maintain a regular bedtime).
4. Explore the Subscription – If you’re serious about tracking progress over weeks or months, consider the premium subscription. It unlocks deeper sleep analytics, body‑fat estimations, and personalized recommendations.

Final Verdict

The Luna Ring’s Black‑Friday deal—66 % off—makes it one of the most compelling offers for anyone looking to get into fitness tracking without spending a fortune. Its compact form factor, decent battery life, and robust set of metrics strike a good balance between functionality and affordability. While it might lack some of the more advanced analytics of its pricier competitors, the Luna’s value proposition is clear: get a reliable ring‑style tracker for just around $70 and enjoy the same core health insights that would otherwise cost three times as much.

If you’ve been skirting the idea of a wearable because of the price tag or because you’re wary of having a “smart watch” on your wrist all day, the Luna Ring offers a neat, discreet solution. And given the steep discount available only through Black Friday, now’s the perfect time to make it yours. Just remember—once the promotion ends, the price will jump back up, and you’ll be paying a premium for a piece of tech that’s still very capable.

Happy fitness tracking—and happy Black Friday shopping!
