Luna Ring by Noise: masterful in many aspects

“Technology ought to work in the background and invisibly fulfill its purpose.” Should you fall into this particular category, an ingenious ring could be the best option for you. A few weeks ago, I had the chance to try out the Boat Smart Ring (review), and I presently have one from Noise that’s called the Luna Ring. These observations might be useful if you want to know how well the device works.

There are five sizes and three colors available for the Luna ring. In contrast, there are only three sizes and one color available for the Boat offering. Thus, with its first smart ring, Noise is undoubtedly attempting to offer more options and appeal to a larger market. Though it should be basic overall, there are a few noteworthy elements.

Second, there is a small ridge on top of the ring that you can feel when you run your finger over it but is hardly noticeable. This helps you to know how to wear and place the ring such that the sensors face your palm and not any other orientation. To measure something accurately, this is necessary. There isn’t an obvious Pogo pin connector for charging here, in contrast to the Boat ring.


The Luna Ring, which functions similarly to a fitness band or smartwatch, uses PPG sensors to detect parameters including heart rate, SpO2, and heart rate variability, a motion sensor to track activity, and a temperature sensor to assess skin temperature. However, as the ring is only intended to be worn 24 hours a day, 7 days a week, while the app syncs, gathers, and shows the data captured, there is no way for you to engage with it. In this regard, the Boat Smart Ring appears to have the advantage—at least theoretically—because it has a touch-sensitive area that can be used to flick through quick films, operate a remote camera shutter, and other functions.

I believe Noise did a good job of getting a third-party organization to examine and evaluate its values, as the main selling point of a smart ring is that it rests near the skin and can record metrics that are meant to be more accurate than those of a traditional smartwatch. The International Institute of Information Technology Hyderabad, with which Noise has partnered to verify the quality of the health data, claims that the data collected by the ring is 91% correct. and that undoubtedly benefits Noise by giving potential customers greater trust.

Additionally, Noise provides a sizing kit ahead of time so that prospective customers can try it on and choose the size that fits them the best.

App and connectivity:

Speaking of the software, this gadget is compatible with the iOS and Android versions of the Luna Ring app. The app’s home screen shows a dashboard that summarizes all of your activity and sleep, along with the rankings it has given to other categories. You may go down into each of the other tabs to view specific metrics and past data related to sleep, preparation, and activity. Additionally, the app makes recommendations and flags areas where you may be lacking in exercise, enough sleep, or other lifestyle factors.

The fact that you have to manually add workouts and that you can only do so for the current day is one feature that I thought was a little peculiar. You cannot travel back in time with the app to add a workout that you might have forgotten to add. The app also allows you to see the battery life of the ring. Unfortunately, the software does not yet allow data syncing with Google Fit or Apple Health.

Performance and battery life:

The Luna Ring’s primary selling point is its ability to collect physical data and health measurements. Based on my own testing and additional data from other fitness trackers and smartwatches, I believe it does this well. After syncing, the Luna Ring app shows information about your daily activity, sleep habits, heart rate variability, and other factors. It also provides a thorough analysis of your physical activities.

Under each of these categories, you may get more information and view historical statistics and trends by going back in time. The program also determines your readiness score, or how prepared or ready you are to go about your day, based on these numbers. This bears some resemblance to the body battery values displayed by Garmin on their smartwatches. Please be aware that the score displayed here is merely an estimate, determined by algorithms that use information from the different sources that the Luna Ring collects.


The Luna Ring seems pricey for its Rs 15,999 asking price, and I’m not sure if the smart ring category will be able to gain traction at these price points. While comparing the features of a smartwatch and smart ring, many people may not be too concerned about the accuracy of activity and health data and may be perfectly content to view simply indicative numbers. Noise has a sizable portfolio of its own in the smartwatch market, making it a formidable rival. In addition to early adopters, people who dislike wearing watches—especially at night—might find a smart ring appealing.

As I previously indicated, the gadget is also effective for people who think technology should be used in the background and without making any noise. And to be honest, I think the Luna Ring can accomplish that to a very good degree. All things considered, I believe Noise’s Luna Ring is a good effort in the correct direction; the question is whether that approach is suitable for you.
