Greatest Costs At present: Luna Ring Gen 2

The Luna Ring Gen 2 is one other subscription-free good ring that desires to eat into the gross sales of the Oura Ring 4 and Samsung Galaxy Ring.

India-based Noise’s second-generation Luna turns to AI in an try to face out from the rising variety of linked rings. It makes use of machine studying to supply recommendation on exercises and enable you make higher diet choices.

Whereas the variety of good rings out there continues to be comparatively small, there are already some robust subscription-free choices on the market. Does the Luna Ring Gen 2 make a powerful sufficient case to be one other one it’s best to put in your finger?

Right here’s how issues performed out after I slipped on the Luna Ring Gen 2.

Design & Construct

• Obtainable in 5 color finishes
• Comes with transportable charging case or a dock
• Waterproof as much as 50 metres

The Luna Ring Gen 2 has comparable design traits to many different good rings. It’s made primarily from titanium, with a non-allergenic moulding on the within the place you’ll discover the all-important sensor bump.

The sensor array, whereas not uncomfortable, did sit comfortable on the underside of my finger.

There are 5 color choices to select from – Stardust Silver, Lunar Black, Sunlit Gold, Midnight Black and Rose Gold. The model I examined is the Daylight Gold mannequin, which has picked up just a few little scratches throughout testing. The ripple impact on the titanium helps to provide it a particular look to assist set it other than different good rings.

In case you’re not sure of match, there’s a free sizing package out there. I’ve discovered sticking to the identical dimension as different good rings has acquired me a very good match total.

The way you select to cost the Luna Ring will impression on how a lot you pay for the ring total. The pricier possibility is to seize it with the gorgeous transportable charging case (pictured). You may as well go for the dock charger to avoid wasting cash (detailed pricing is under).

If you wish to take it for a swim, the 5ATM rated design means it could actually survive submerged in water as much as 50 metres depth. I’ve worn it within the bathe, within the pool and even in heavy downpours and the Luna has survived all of these situations.

Health & Monitoring 

• Tracks step, sleep, coronary heart charge and stress
• Free Luna app out there for iOS and Android
• LifeOS insights and steerage

There are some fairly normal good ring sensors in play right here that care for monitoring your knowledge. That features constantly protecting tabs on coronary heart charge and every day step counts.

A inexperienced optical sensor is current to cowl coronary heart charge monitoring, a pink one for blood oxygen monitoring and there’s additionally room for a pores and skin temperature sensor. Motion monitoring is roofed by a 3-axis accelerometer.

Knowledge is saved within the Luna app, which has a pleasant, stylised interface, breaking down every day totals, sleep, readiness scores, exercise monitoring and the Luna AI options. 

For sleep, I’ve been carrying it alongside the Oura Ring 4 and knowledge like sleep length and interval of sleep in addition to deep and REM sleep levels had been fairly comparable. Along with these core sleep stats, you too can see tendencies on hitting advisable sleep targets, whether or not you’re hitting enough restorative sleep and these are all cleanly defined within the app.

Subsequent up is Readiness, which is a metric different rings have additionally adopted. This seems at metrics like coronary heart charge, respiratory charge and temperature. Once more, Readiness scores had been surprisingly much like these captured by an Oura Ring 4.

There are some properly introduced summaries of that readiness knowledge that will help you higher perceive what your scores are telling you. I’ll say, although, that coronary heart charge readings normally had been a bit on the beneficiant facet. This isn’t probably the most correct good ring for monitoring coronary heart charge.

Subsequent up is exercise monitoring, the place you’ll be capable of see every day step totals, distance coated, energy burned, together with displaying contributing components to your total exercise rating. The every day step totals didn’t look wildly out from different health trackers.

If you wish to monitor a exercise, you are able to do that manually. Runners and eager walkers additionally profit from computerized exercise recognition, which has labored fairly reliably in my testing.

Then there may be Luna AI, which you’ll be able to view as your hub to be taught extra in regards to the metrics this ring can monitor, in addition to organising exercise and weight loss plan plans. There’s additionally a every day digest characteristic, which neatly outlines a few of your key knowledge factors and what they’re telling you. Producing exercise and weight loss plan plans may be very ChatGPT in method and proper now, it doesn’t really feel vastly personalised or compelling to make use of.

Battery Life & Charging

• As much as 5 days battery life 
• Charging case provides 30 days battery
• Absolutely expenses in 120 minutes

I’ve managed to get roughly 5-6 days of battery life out of the Luna Ring on a single cost.

That’s what’s quoted by Noise, so it does no less than meet these claims. That’s nonetheless in need of the battery life you’re going to get from the Oura Ring 4, Samsung Galaxy Ring and RingConn Gen 2. You’ll see notifications from the app when it will get low to be sure you don’t get caught quick on battery.

The transportable ‘Surge Cost’ case has a large 500mAh capability battery. When full, it offers you sufficient battery to energy up for 30 days. When it does get low, I’ve discovered it takes roughly an hour to get from 0-100%, which is a charging charge largely in step with the competitors.

Worth & Availability

The Luna Ring Gen 2 launched in July 2025, priced from £269/$300. That makes it cheaper than the Oura Ring 4, the place pricing begins at £349/$349 and goes rather a lot increased for sure fashions.

As talked about earlier, that beginning value will simply get you the usual charging dock, or you possibly can spend £299/$329 for the transportable charging case, which is a small value to pay for the added comfort.

Although there are costs out there in {dollars}, the official retailer says the Luna Ring Gen 2 isn’t out there within the USA.

Not like Oura, there’s no further month-to-month or annual charge to pay to make use of the entire out there options. Meaning it joins the likes of the Samsung Galaxy Ring ($399.99), the Ultrahuman Ring Air ($349), Round Ring 2 (from $349) and the RingConn Gen 2 ($299) as rings the place you simply have to pay for the {hardware} alone.

Take a look at our listing of the very best good rings you should buy proper now.

Do you have to purchase the Luna Ring Gen 2?

I feel there’s a good quantity to love in regards to the Luna Ring Gen 2 and what it provides as a wise ring. The design is good, the app is fairly slick if a bit of busy, and many of the monitoring is strong total.

I do assume it’s let down in a few key areas. Most notably with the guts charge monitoring and a battery life that’s not fairly up there with the competitors. There’s a lot to work with right here and I do assume should you worth options like sleep monitoring and giving your knowledge context, the Luna Ring Gen 2 does a very good job of that.

It was a wise transfer to cost it under the competitors, although, because it doesn’t compete effectively sufficient in all areas to beat the very best within the class.
