### Luna Ring Review: A Budget-Friendly Smart Ring with Potential for Enhancement
The market for smart rings is swiftly growing, with pioneers such as Oura and Ultrahuman paving the way for this new category. Now, Noise, a prominent wearable brand in India, has launched the **Luna Ring**, targeting consumers seeking a cost-effective option compared to pricier competitors. Priced at ₹19,999 ($238), the Luna Ring is considerably cheaper than the Ultrahuman Ring Air, which is priced at ₹28,499 ($340). But does this attractive price compromise its functionality? Let’s explore further.
#### **Design and Build Quality**
Even with its budget-conscious pricing, the Luna Ring does not compromise on aesthetics. It boasts a **titanium build**, providing a sleek and sophisticated appearance. Available in five color variations — silver, gold, black, and matte black — the ring weighs roughly **three to four grams**, ensuring it feels light and comfortable for all-day wear.
Nonetheless, similar to many smart rings, the Luna Ring is slightly broader than traditional rings. While this may not be immediately apparent, it is susceptible to scratches over time, particularly due to its **PVD coating**. Overall, Noise has impressively crafted the design, allowing the Luna Ring to resemble pricier options such as the Ultrahuman Ring Air.
#### **Sensor Suite and Features**
The Luna Ring is fitted with a typical assortment of sensors, including a **heart rate sensor**, **blood oxygen (SpO2) sensor**, **skin temperature sensor**, and an **accelerometer**. While these sensors are rather standard in smart rings, they create a solid foundation for monitoring key health indicators.
A notable characteristic of the Luna Ring is its **sleep tracking** capability. Wearing a ring to bed is far less intrusive compared to a smartwatch, and the Luna Ring provides **valuable sleep insights**. You can track your sleep cycle, receive a sleep score, and get recommendations for improving your rest. Additionally, it presents a **readiness score**, consolidating your activity and health metrics for a comprehensive overview of your daily preparedness.
#### **Activity Monitoring: A Mixed Bag**
While the Luna Ring shines in sleep tracking, its **activity monitoring** functionality is lacking. The ring tracks fundamental metrics like heart rate and skin temperature throughout the day; however, it falters during more vigorous activities like **cardio workouts**. For example, when using an exercise bike, the Luna Ring’s data resembled that from basic fitness trackers, lacking the precision necessary for dedicated fitness monitoring.
If precise heart rate readings and training load insights are your priorities, you may need to invest in a **smartwatch**. Although the Ultrahuman Ring Air faced similar initial shortcomings, subsequent software updates greatly enhanced its performance. Unfortunately, the Luna Ring has not yet undergone such improvements, putting it at a disadvantage.
#### **Battery Life and Charging Challenges**
Battery longevity is another aspect where the Luna Ring struggles. While Noise claims the ring can endure up to **five days** on a single charge, actual usage suggests otherwise. In my experience, the Luna Ring barely lasted beyond **two days** before needing a recharge, which is a day less than what I achieve with the Ultrahuman Ring Air.
The charging method also leaves something to be desired. The ring needs to be precisely aligned with the charging stand’s ridges, and often, it fails to charge correctly on the first attempt. This tricky charging process can be irritating, particularly in contrast to the more user-friendly charging solutions found in other smart rings.
#### **Software and Notifications**
The companion app for the Luna Ring is straightforward and connects with **Google Fit**, but it falls short on customization features. One of the most frustrating parts of the app is the **excessive notifications**. The app constantly inundates users with notifications about connecting to the Luna Ring, leading me to disable this notification channel within an hour of using the device.
Furthermore, the app demands **alarm permissions**, even though alarm setting is not an option on the ring itself. This is a peculiar and somewhat intrusive request that I have not encountered with different wearables. While connectivity generally remains stable, there were sporadic instances of data failing to sync automatically.
#### **The Conclusion: Is the Luna Ring Worth It?**
The **Luna Ring** presents an appealing choice for budget-conscious consumers, though it is not without its drawbacks. On the one hand, it features a **lightweight design**, provides **helpful sleep insights**, and is **budget-friendly** compared to rivals. However, its **inconsistent activity tracking**, **subpar battery life**, and **notification overload** diminish the overall experience.
If your primary focus lies in **sleep tracking** and you can overlook occasional issues, the Luna Ring could be
