Notes
Notes
1. Sleep monitoring can record night sleep and naps that last more than 20 minutes. Sleep Breathing Quality tracking needs to be enabled in the Zepp App.
2. This product and the Zepp App are not medical devices and cannot be used for medical purposes, or as basis for diagnosis of any medical condition. Detection results are provided for reference only. Please consult professional medical institutions if you feel unwell. 24-hour monitoring of heart rate and blood-oxygen saturation (SpO₂) need to be enabled in the Zepp App. Abnormal heart rate alerts and the preset value need to be set in the Zepp App. To measure blood-oxygen saturation (SpO₂), please wear the strap tightly at one finger-width from the wrist, and keep your arm still for best results. SpO₂ alerts are sent if the detected rate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of 80%. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement. The 24-hour stress level monitoring needs to be enabled in the Zepp App. Alerts for high stress levels are based on the preset value, and prompts for the breathing exercise need to be enabled in the Zepp App. Smart health alerts need to be enabled in the Zepp App. To process the one-tap measurement and other manual metric measurements, please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.
3. Fitness app availability may vary depending on your country or region. Apple Health is only available on iOS devices, and Google Fit is only available on Android devices.
4. The battery life may vary according to the settings, operation conditions and other factors. So the actual result may differ from the laboratory data. Typical usage scenario: Wear all day; heart rate monitoring and blood-oxygen detection is always on and measures continuously; sleep monitoring and auxiliary are enabled with 8 hours of sleep breathing quality monitoring; stress monitoring is enabled; exercise three times a week while linked to your smartphone's GPS for 60 minutes each time.
5. According to the ISO 22810:2010 standard, the Amazfit Helio Strap achieves a rating of 5 ATM, for a water-resistance of up to 50 meters, and is therefore suitable for splashes, snow, showering, swimming. It has passed third-party testing conducted by SGS, and the report number is SHES250300449771. Remove the strap when taking a hot shower or trip to the sauna, since too much steam can affect the seal and make it less water-resistant in future. Avoid using cleaning agents such as soap, hand sanitizer, body wash, or lotion to clean the watch, as residual chemicals may irritate the skin and corrode the device, potentially affecting its water resistance. If accidental contact occurs, rinse the watch immediately with clean water, soak it for 30 minutes, then remove it and wipe it dry with a clean, soft cloth. For more information, please visit the support page at: support.amazfit.com.
6. The material used for the packaging box is 100% recyclable, with naturally degradable materials including mineral-free inks and anodized aluminum used in the bronzing process.

Great first fitness band experience
I enjoy wearing the Helio strap. It's lightweight and very comfortable. I appreciate the data collected and look forward to seeing my sleep results each morning. I'm happy the battery charge is lasting so long.
I’ve been using the Amazfit Helio Strap for 5 now, and it’s become a solid addition to my training routine, splitting time between weightlifting and padel. The recovery metric has been especially useful, it helps me gauge whether to push harder or dial back a session based on actual data, not just how I feel. The design is comfortable/lightweight for all-day wear — adjust to your experience. Battery life lasts around [10 days], which [is more than enough / falls a bit short] for how I use it. Overall, I’d recommend it to anyone for exercise, padel, swimming, etc.
I am trying the device now and I really recomended
I purchased 4 bands, one for each person in my family. I have been wearing mine since it arrived (>2 weeks). Everyone was very happy with the gift, and super excited to start using it to track workout data. Highlights: Charging last 10+ days. Very happy with the long charge and the quick time to recharge, I can usually get a full charge while I am getting ready for work. Detection: Very accurate with cardio workout detection. Not as accurate with weight workouts. Food tracking: Pictures are convenient and favorites make it easy to set up your routine meals. Wish list: add a simple (water++) button to the interface to make tracking water intake easier. Bands: The velcro, works well, but we have two smaller wrists in our family, so we may have to look for a smaller band for them. Overall, highly recommended for young adults getting started on tracking fitness and parents who take tracking their numbers and progress as a priority. So far, happy with my purchases, will update again based on performance! Thanks for a good product and a Christmas gift home run!
Excellant results from such an affordable Health monitor. A ++
Good value and great app. Only features missing would be a water and fasting tracking. I also work graveyard shifts so the sleep tracking is off despite me setting my bedtime routine. Besides that 10/10
It’s an amazing product, I change from whoop to this one and maybe it’s not a 100% whoop killer, every new technology for company is low, but with a very good projection to perform and bring new features to be one of the top wearables in the market!!
The Helio strap is a good choice for someone who loves the look and feel of the Whoop. I think the band that comes with the Helio strap needs to be worked on a little bit when coming up with new bands for the Helio strap it feels a little bit small and bulky. I love that you don’t need to subscribe to a premium platform plan you can get all of your data that you want to look at in the Zepp app. I think this is a good product for the price point and the quality is good enough for most users to enjoy it!
Its good but its should be more strap for it , sometimes you need to change the strap , also for people who have blood pressure they need to check it if you have to update , but at all its very good. Regards
Misleading purchase ...The faceless Amazfit Helio strap doesn't inform the buyer that it DO NOT vibrate once you reach your step goals. For a 99 dollar fit device this is at least one obvious feature it should have .
This is my first wearable fitness tracker. I'm a big watch guy so I've always shyed away from any screens on wrist. The app is quite insightfull, I find myself looking at my stats quite frequently. The only improvement I'd like to see is a more comfortable, higher end looking strap.
So far Amazfit has been great considering the price. However, the device already froze a couple of times with no clear reason. Without a hard reset button, you need to run to a charger and place-and-remove five times quickly to hard reset it, which is annoying. On top of that, there no many options of wristband so you cant have a second one when the first is washing, options other than velcro, or nicier material for when you go for work.
Great battery life, tracks all the metrics I have been tracking on my Apple Watch. Being a watch nerd i have a good size collection so having the Helio allows me to use my watches more frequently. Only gripe is the lack of a bicep strap, but sounds like that is getting sold soon. Overall, great product!
I like the features I understand. Too bad they're not all explained.
So far so good. Exactly what I was looking for
wanted a health band for day to day health tracking and sleep. looks nice and feel comfortable wearing the helio band. dont need activities as i will be using my apple watch for exercises as i want to have live feedback on my hr. all in all very happy with the purchase as it meets all my needs and at a good price(unlike whoop). Overtime with improvement to the app, it has the potential to be a whoop killer.
Not the whoop killer I thought it would be. But if they can sort out all the hundreds of false self started actives. Then we might be on to something!!
I canceled my Whoop when I saw this was out! I’ve had mine now for 6 days and I still have 45% of my battery left!
Everything i expected plus.more. finally a company made a faceless device that doesn't have an outrageous subscription cost! Its accurate, cost effective and does what i want it do.
This is very intuitive and its readings match Applewatch. Battery life is amazing.
The user experience has been very good. The app has a user friendly dashboard and all my data are easy to find. AI based auto tracking of activity is a good to have feature, but I only wish there was a physical button to start the activity, instead of opening the app. Maybe next version can incorporate GPS along with a physical button!
Does what it claims for less $ than some of the better known brands that require subscriptions to unlock/view your own data.
Died in less than a week, purchased direct from Amazfit. The worse problem is their support email box is full and bounces. Called support number during their business hours, estimated 4 minute wait. 20 minutes later, goes to VM. I previously bought a mid-tier sports watch from them that is so dim it is unreadable in daylight. Better buy a premium brand or cheaper no name Chinese clone. Amazfit is apparently the same low quality and zero support or returns. Maybe they are the same junk with better marketing and paid influencers and reviewers. Let's hope there was a temporary operational problem that will be quickly resolved.
1st month review Battery live as advertised: ~10% per day used all day long ( just get it off while taking a shower ). Last up to 10 days. Recharge time, under 1 hr. Out of the box, without subscription, features are great: stress, sleep, steps, heard-rate and activities (training sessions) tracking.
As a young athlete the strap tracks everything I need plus more and if you want to do a hyrox the training programs are truly over the top amazing I love this band and it’s battery life too highly recommend it to any athletes!!!!
