Great item I’m not a runner but a strength athlete and this is great for that no subscription either unlike the much dearer whoop , the strap could be bigger but this lasts 10 days when charged , picks up work outs without telling it , monitors sleep , as well as lots of other things , just easy to use and the stats it gives you are easy to understand, like the bio charge which is like your body’s battery that goes up and down during the day depending on what you do , maybe no good for paid athletes, but good enough for a fat old bloke that likes moving heavy stuff

Having had a number of different fitness trackers, including whoop, Garmin and alike, I wanted to give this a go as a screen free alternative without the subscription of woop. Have been wearing for a couple weeks and I can say, for the price, it does the job. It’s comfortable to wear, is light weight and looks very much like a whoop band. Battery life is pretty good, I’ve charged it 2 to 3 times in as many weeks, and it is quick to charge back to full battery. The small charger is a worry in a sense that it’s easy to misplace and lose if you’re that way inclined. Tracker wise, it seems fairly accurate and automatically picks up my exercise. It does say my resting heart rate is consistently in the 80s, which is very different to other trackers I’ve had and I don’t believe to be all that accurate knowing my level of fitness, but as I’m not concerned or focused on that, it’s easy to overlook. overall, if you’re not super serious about tracking all things fitness then this is a good budget option for you.

Having previously given up on Fitbit when google bought them over, then moved to Garmin in a smart-watch, briefly to Polar for swimming, I can safely say the Amazfit Helio is the best fit for tracking every day life. I have fatigue like symptoms – and the ‘BIOCHARGE’ score is invaluable to keep an eye on rest, recovery and not pushing my mental or physical activities too hard. When I do, they equally and efficiently track the correlation between the day before and how I’m feeling then recovering the next few days along with giving helpful insights into what to watch out for, and what activities my body is finding draining.If you have Fatigue, CFS, Fibromyalgia, POTS or long covid, this is the health and fitness tracker for you.Along with the already mentioned BIOCHARGE feature, it also gives an exertion score, workout and activity log and pretty in-depth sleep and nap tracking.The wristband itself is a lovely only very slightly stretchy fabric band with Velcro style stap which stays put but doesn’t dig in or cause irritation like some of the silicone based ones can. It is rated to 5ATM, so whilst it is splash and swim proof, I choose not to take it into the shower, as it officially doesn’t withstand ‘direct water pressure’ like from a shower, however they do note on the website that it is indeed showerproof too. Feels sturdy, and the band protects it from scratches and drops when it’s off – the included magnetic charging mini attachment has pretty weak magnets so is a bit hard to sometimes position ‘just right’ however the battery lasts well over a week, so I have no complaints.Best of all? The Zepp app is totally free, and subscription free forever.And the only ‘paid-for’ add-ins which I despise in other products, when I’ve already shelled out for a device and/or subscription, is some silly meditation noise tracks AI tuned to you and your body! 😂

I have recently bought into the Amazfit/Zepp system having been a Fitbit user for many years, and I have to say currently I am impressed.General wear : I couple this Helio band with a T-Rex 3 watch, depending on the activity I am doing. The Band is great for just day to day wear when you want something vaguely unobtrusive and don’t need the screen or notifications continually buzzing. I am a bit of a watch lover, so being able to wear it as well as a normally watch is a huge bonus ( and it doesn’t look like i am being weird and wearing 2 watches ). It is really light, but I would say that having reasonable sized wrists the band could be a bit longer as there isn’t much overlap ( see picture, apologies for the quality ), but it still fits, does up and is really comfy.Performance : I ran this alongside my Fitbit for a week, so that I could judge what the differences were likely to be. First thing that struck me was how close the data was to each other, but I was super impressed with the extra info that this provides over and above the Fitbit. The Sleep data is comprehensive and covers all the relevant things you might need to know, steps seems to be pretty good, although is much better at filtering out the “white noise” that can be detected as steps by some other devices, heart rate is pretty much exactly right, blood oxygen readings are a bit more random, but I would expect that really and is only a guide ( having recently had Pneumonia this has been quite an important reading for me ).But the thing I am currently most impressed with is the general workout tracking. Both this and the T-Rex have similar set ups, and picking the right workout is key to getting the right information. There are a huge amount to choose from, and I would highly recommend choosing. The Auto function for me is too random, and picks up things that aren’t workouts, so I have both devices set to manual selection rather than auto detect. Once selected the system runs throughout and records everything you would need to know accurately and comprehensively.The recovery info is great, and gives a real insight to how hard or not you are training.The battery life has surprised me. a week of full use dropped the battery to 65%. I guess that a large chunk of the life comes form the fact you aren’t running a screen or GPS form the devices ( only through the app, which does work nicely ), but even with tracking on it doesn’t seem to use a massive amount of battery compared to other devices.Overall then, subtle looks, loads of features and a seemingly supernatural battery life, for no subscription charges. Whats not to like ?The best part for me though is that all of this info comes at a low up front cost and zero monthly subscription.

Excelente pulsera.
Funciona sin problemas en México (a pesar de que no ha sido presentada oficialmente a día de hoy), con todas sus métricas activas (frecuencia cardiaca, oxígeno continuo, sueño, estrés, esfuerzo, etc.). Se sincroniza sin fallos con la app Zepp y las actualizaciones llegan normalmente. La construcción es cómoda, ligera y se nota precisa en las mediciones.

Prima activiteitentracker. Registreert alles goed, zelfs met krachttraining. Naar mijn idee ook redelijk nauwkeurig.

A Perfect Choice Before You Jump to WHOOP or Higher-End Trackers
Sleep Tracking:The sleep tracking feature is exceptionally accurate. It not only tracks my night sleep precisely but also detects short naps during the day, which most trackers tend to miss.Temperature Monitoring:The temperature tracking works surprisingly well and gives consistent readings. It’s a subtle but valuable feature that adds to overall health insights.Heart Rate Tracking:I didn’t have another device to cross-check the heart rate accuracy, but based on my experience and other users’ reviews, it seems reliable and stable during different activities.Workout Detection:This is where the Helio Strap truly shines. I just start the workout mode before training, and it automatically detects the workout type — whether it’s arms, shoulders, or legs — with remarkable accuracy. Out of more than a month of use, it has only misidentified my workout twice, which is impressive for a strap at this price.Battery Life:The battery life is excellent. It easily lasts long enough to forget about daily charging — another big plus.Overall Verdict:Considering its features, performance, and accuracy, the Amazfit Helio Strap offers incredible value for money. You’re genuinely getting far more than what you pay for, especially compared to other fitness bands in the same category.

Best heart rate monitor device in the market
Best heart rate monitor in the market by far. I compared the metrics to those collected using a Polar H10 hrm chest belt and the results are amazing ! The Helio Strap has identical results to those coming from the Polar ! I even compared the sleep tracker to the one of the Apple Watch Ultra 2 and the results were very close. I’m really impressed by this device and by its price !
