Amazfit Helio Smart Ring, Monitor Sleep/Heart, Water-Resistant, iOS/Android

I purchased this ring knowing it would be the push I needed that would inspire and encourage me to get back into working out again. I watched several video's and researched what size I should order(without having to purchase the size kit). I did the strip of paper measuring technique several times and got slightly different measurements each attempt, but it was fairly close. Then I did the string/dental floss measuring technique, which I found the measurement to be mark on each time. I determined I was just slightly over a size 12 based on the inches listed on the ring size guide. I am 6ft3inches tall and weight 200, I would consider myself tall/thin/slightly athletic in build. My glove size would be a mens large, but due to finger length I wear and xl. After watching several online videos and reading articles with men claimed to be wearing different sizes of the available sizes (8, 10, & 12). I went ahead feeling hopeful and ordered the ring, knowing I could return it if it didn’t fit. The ring is said to work best on your index finger, but can also be worn on the middle finger and lastly the ring finger. Immediately upon arrival I opened the beautiful Amazfit Helio ring box and was delighted with the look, feel, and quality of the ring. I then tried to put the ring on my index finger on my right (dominant) hand, but it barely went past the knuckle and I didn’t feel comfortable trying to force it any further. I then did accomplish to slide the ring onto my index finger on my left hand, but had to remove it due to lack of blood flow and finger starting to turning red. Then I tried my middle finger on my right hand, the fit was near perfect/very good. I then tried my ring finger on my right hand, the fit was slightly loose and was very comfortable(my preferred style). I then put the ring onto my middle finger on my left hand and felt that was the best fit of all fingers, but the ring touched and banged against my wedding ring. That would not work for me, so I placed the Helio ring back onto my middle finger on my right hand. If there was a size 13 I would presume that would be my perfect fit for my index finger on my right hand, and I plan to purchase one of those once this ring gets to the end of its life and more ring sizes are available. I hope this helps you get an idea of what you may need to order. My recommendation is to use the string/floss technique since it easier to get a consistent accurate measurement that way. Update: Having to move the ring to my ring finger on right hand each night due to slight nightly swelling I think due to getting to hot. Definitely could have used a size 13. The usb-a to usb-c cord that came with the ring charger, charges much slower than when I use my own usb-c to usb-c cord.

This is an amazing smart ring though it does have a few minor downfalls. The sensors are extremely accurate and it collects a ton of data. At first I thought the "emotion detector" was going to be a nonsensical filler, but after being in a few stressful situations I received a notification asking if I was stressed during a certain time period. Each time it provided accurate feedback and then logged that information for later review. My personal favorite feature is the sleep sensor. As someone with sleep challenges at times it is really great to see how well I'm sleeping and what I can do to fix it. The heart rate, step counter and oxygen level monitors are phenomenal as well. Though one of the few downfalls of this ring is that if you want to track a workout you have to enable it through the Zepp app compared to similar smart rings that sense it automatically. It's not a deal breaker by any means but it can be a little annoying if you forget. The only other "complaint" I have is that the battery doesn't last as long as advertised if you have all the functions enabled. With everything enabled the battery lasts about 2 1/2 days, not bad but could be better. Not all the functions are necessary so if you don't enable the stress/emotion sensors and set the heartrate monitor to scan every 30 minutes instead of every 10 minutes I'm sure the battery will last longer. Now the main thing that convinced me to buy this ring instead of any other brands I was looking into was the fact that THERE IS NO SUBSCRIPTION!!! Normally Amazfit charges a subscription fee in the Zepp app for their other devices in order to access Zepp Aura Premium and Zepp Coach Premium. This ring gives you access to both services FOR FREE FOR LIFE!!! Zepp aura is a relaxation meditation service and Zepp Coach is an AI powered "personal trainer" of sort. I personally wouldn't pay for it if it wasn't included with the ring, but they're great add-ons. Overall for $170 this is an AMAZING smart ring if you don't want to fork over $400 plus a subscription every month for the competitors. As long as you're okay with a fairly average battery life and having to enable work out tracking yourself I think this is a pretty good option.

2nd edit: It's junk, I recommend you look elsewhere. Refuses to be consistent in tracking, last 3 nights recorded no sleep data. After the second week on iOS it has refused to track for 7 consecutive nights. THE ZEPP APP IS AS WELL AS THEIR HEADPHONES (2/3 DIED SINCE 8/12/25) AREALSO HALF-ASSED!! 1st edit: Became inconsistent within two months of using only to track seep. Last week only recorded 1 of 7 nights of sleep. That was on android, switched to apple and it seems to be back to normal. 3 of 3 nights tracked. OG: Comfortable, good data. Got it to track sleep and swimming. Works well so far.

I know this ring isn't very popular, but for what it actually provides if your an amazfit user it's actually worth the cost if you enjoy a lot of the a.i coach features and sleeping features without having to pay the 'premium' price. Especially for the lifetime membership to the premium features alone. I usually use mine before bed, I put it on it's charger when I wake up after syncing before starting my day. I find that it's decent and reasonable when it comes to tracking. I absolutely love the more 'balanced' approach for getting the averages for Sleep tracking. The battery life tends to last about 4 days with ALL FEATURES turned ON. I find the fit comfortable, and it doesn't fall off when i sleep. Imma be honest, sometimes I forget its on in the morning especially if i'm a bit busy. So it's nice to know I got a long battery life to bypass that forgetfulness XD. As far as functionality, it does what it needs to do. I love it like I said for the above points. Especially the 'free premium' for life thing.. Could you imagine if fitbit offered something like this? Or any of the other's that actually said 'buy my ring, unlock everything for free, for life!'. You can't get better then that, especially with a company that's so passionate about their products that they literally update at least 5-8x a year from what i've been seeing. I fell in love with this company after buying a 35$ Bip 3 watch.. which when all was said and done.. I preferred over my fitbit sense, and the app involved. Since then I have bought a balance, and while waiting for the balance 2, I have actually recommended their products to actual people.. (Something we all know no one ever does.. recommend products unless it's absolutely worth bringing up. Cause let's face it ain't no one gonna be questioning you where you got a sleepers ring, watch etc especially when realistically they all look the same!).

It's mediocre. It does heart rate and sleep monitoring, but doesn't seem super accurate and the battery life is abysmal (2 days max until it's <20% which means it won't last through the next night). It's also blindingly bright at night, and the green heart rate monitor light stays on the entire night continuously which is obnoxious and distracting if you share a bed. I like the appearance, it's "low key" and looks better than other smart rings on the market. I wish the battery life was longer and they could do something about that heartrate light while monitoring sleep.

The ring, when working, appears to properly and sufficiently record your sleep. There are still daily notifications about 'upgrade' offers to buy into the subscription model. Bought the ring in August and by February it couldn't hold a charge and therefore couldn't stay synced to my device. Even before then I would rate it as a modestly cheaper version of the Oura ring. The app features are limited in terms of types of workouts - it only allows for running and cycling (indoor or outdoor). And when I tried to "trick" it once to record my volleyball workout, the app said it stopped recording part way due to my heart rate readings being too variable and it concluded I was no longer working out. Still wish it was much cheaper than Oura considering performance and options but I tried it! Would not buy again.

I've been using the Amazfit Helio Ring (size 12) for a while now, and it has truly been a game-changer for my health and well-being. I initially got it to better understand my sleep, and it has exceeded my expectations in every way. The ring's sleep tracking is incredibly detailed and insightful. It goes beyond just telling me how long I slept, providing me with valuable information about my sleep quality, including deep, light, and REM sleep cycles. What's been most helpful for me is the data on things like hypopnea episodes. This is information I can now share directly with my doctor, which has made our conversations about my sleep health so much more productive and evidence-based. The data is presented in a clear and easy-to-understand way, making it simple to track trends and identify potential issues. But the Helio Ring is more than just a sleep tracker. It also helps me document my daily life in a way I didn't expect. The data it collects on my daily reactions and mood has been fascinating. By correlating my activity levels, sleep quality, and other biometric data with my mood, I'm starting to see patterns I never noticed before. This self-awareness is invaluable and has helped me make more conscious choices throughout the day to support both my physical and mental health. The ring itself is comfortable to wear 24/7. It's sleek and lightweight, so I barely notice it's there. The size 12 fits perfectly, and the battery life is excellent, so I don't have to worry about constantly charging it. Overall, the Amazfit Helio Ring has become an essential tool in my personal health journey. It provides me with objective data that empowers me to have better conversations with my doctor and to gain a deeper understanding of my own body and mind. If you're looking for a smart ring that provides comprehensive and actionable health insights, especially for sleep tracking, I highly recommend the Amazfit Helio.

So far, absolutely no complaints. Seems high quality, product is pretty neat. Charges fast. I can't tell you how accurate it is, but it seems pretty solid so far. One caveat: sizing runs small for sure. I have a size 8 wedding band that fits fine. This is pretty snug. Highly recommend buying the sizing kit.

Worth the trouble to get the size selection right.

Very accurate and perfectly fits in my finger ( size measured according to amazfit website)

Me ajudou a escolher meu Helio ring

Ive been wearing the size 12 amazfit helio ring on the ring finger and haven't experienced any issues. Wrenching on my motorcycle, doing lawn maintenance, and when working out I use the two finger central leather strap from Olympic lifting/crossfit so the ring doesnt get scratched. The app is easy to understand and the information given helps make informed decisions. I charge it every second day and treat it like a cellphone in that regard. Definitely worth the purchase.

Stopped working Sleep tracking seemed better than other activities
