Why the Signature
One ring, the whole picture
Sleep, staged
Light, deep and REM sleep are staged automatically from your optical and temperature signals. Wake to a sleep score and a readiness view — no button to press, nothing to charge midweek.
The complete sensor array
Three optical and two temperature sensors sit flush beneath the polished outer shell, sampling continuously while you wear it. There is no screen and nothing on the inside to catch on your skin.
Seven days per charge
Our stainless steel smart ring is engineered for low power consumption. A quick recharge fuels up to seven days of continuous health tracking. The compact charging case provides emergency top-ups when you travel or commute, so you never miss your sleep, heart rate and activity data.

Reviews
What buyers say
I love it. No subscription fees. It connects easily.
True to size! Very high quality, I’m obsessed, truly. This ring is by far the best smart ring! What’s not to love? The only downside is I’m cautious wearing it in hot showers. Order yours before they sell out! You absolutely will NOT regret it.
I bought this ring for my girlfriend and she loves it
It tracks all the data I need. So far I don’t have any complaints. It comes with a portable charger case and a physical charger, and I only need to charge it every few days or once a week.
Ease of Use: I received this and it is very easy to set up and start using. Features: I love the features that it tracks. Battery Life: Battery life is just what it says. I would order again!
I am so excited to start using this. It came in the mail today and the set up was so easy. The fact I don't always have to put my apple watch on I'm loving this. And the fact it comes with band covers. I'm so excited
Absolutely love this ring, the app is very convenient, charging lasts, doesn’t weigh.
Just like an Oura Ring, without the big price.
i’m obsessed with this ring i love it so much i highly recommend the app is free and you can’t beat the price 🔥
Ease of Use: What can I say, it’s beautiful and cute. I love you so much. Can I use it?
I love it. No payment for subscription. It’s connects easy

I love this ring SOOOOO MUCH!!! Definitely glad I measured my ring size before purchasing because I wear this day and night! It tracks everything from sleep, steps, heart rate, and connects to my apple health. The app is free and even came with three silicone ring protectors for free. And for a fraction of the price compared to the big name brand…..it’s great!!! Get it DEFINITELY
Definitely worth the purchase! I got a size 7 and it fits on my middle and index finger. After a while you don’t even notice it. Charge lasts pretty good it did die in my sleep the first night. It’s pretty accurate and the app is easy to use definitely recommend.I haven’t showered with it but I have washed my hands and it’s fine.
I’ve been using this ring and honestly really like it! It has a similar look to the Oura Ring without the expensive price tag. It’s comfortable to wear throughout the day and easy to use. I like being able to track my sleep, activity, and other health information. Overall, it’s a great affordable alternative if you want something similar to the Oura Ring without spending as much!
I absolutely LOVE this ring! It tracks everything I want and need to know. If you don’t know your ring size and don’t want to wait long, head to Target to try the Oura Ring sizing kit. The size you get there is exactly the one you should pick. I also love the gold color so much — it’s perfect 🤩
I didn’t know my ring size. They sent a free sizing gauge for me to measure. After I sent them my size, they shipped it out right away. Super fast!
II love this product. It has great features and if you use the app, it can even take a photo for you if you waive your hand.
Love love LOVE. Battery life is insane. It’s super cute i love the rose gold. I got a size 10 and I’m normally 9 and it fits well
Just got it today so far it is a good purchase. Connected super easy and fast shipping took maybe 3 days
