Amazfit Helio Strap Fitness Tracker Wristband, 24/7 Activity & Sleep Tracker with Heart Rate, 10 Days Battery, 50+ Sports Modes, Strength Training, Hyrox Race, Subscription Free for Android & iPhone

The Helio Strap has slipped onto my admittedly bony Mancunian wrist without any fuss. It is a slim, screen-free band that spends every hour quietly funnelling heart rate, SpO₂, stress and sleep figures into the Zepp app. When I remember to fasten my creaking old Amazfit watch as well, the two pieces of kit swap numbers without complaint; when I forget the watch in the scramble to find nursery shoes, the strap behaves perfectly well on its own. Amazfit reckons the battery will last ten days. In real life I have been getting a shade over eight, which feels fair enough considering it is logging every heartbeat and enduring a couple of sweat-drenched gym sessions each week. I like the Strength mode: it counts reps and rest periods more accurately than I manage with my fogged-up glasses. There is even a HYROX setting for proper athletes, although my ambitions rarely stretch beyond Parkrun. Automatic workout detection can be a touch jumpy, once awarding me five active minutes for waddling from sofa to fridge, but a quick dive into the settings soon calms it down. No subscription fees, a feather-light build, reliable sensors and neat links to Strava and TrainingPeaks make the Helio good value. Just remember you are stuck with a single strap colour, and be prepared for the occasional false alarm when you wander round the kitchen. For steady training in soggy Manchester it gives me plenty of data without weighing me down or draining my bank account.

I'm geeky enough that I like to know things such as how far I've walked today, and whether my sleep was good enough or not. But I really don't want to wear a screen on my wrist* - I have enough screens in my life that I don't need another one on my wrist repeating all the information that the others can give me. For a long time, I wore a Whoop, because it was the only screen-less tracker out there - but, brilliant as Whoop is, it's also expensive for the mortals among us. It's designed more for the pro-athlete, the uber-healthy, and the uber-wealthy. Then, last year, Amazfit decided to release a direct Whoop-competitor - the Helio Strap. It's £99 (one-off fee) versus Whoop's £199-£350 per year subscription costs (price varies based on which level of app access you want) and, in my opinion, the Helio Strap is every bit of a match for the Whoop in terms of comfort, fit, and data presented. All fitness apps have a variation of the same theme - they give you a score for your sleep, a score for your exertion, and a score for how you're feeling today. For Amazfit (confusingly, their app is called the Zepp app) your overall score is wrapped up in what they call Biocharge. (Garmin call it Biobattery, Whoop call it Recovery and so on.) Biocharge is an amalgamation of all your other scores and you start the day with a score out of 100 and it depletes as the day goes on, depending on how energetic you are; it is also affected by Heart Rate Value (HRV affects quality of sleep) and can also be an indicator of if you're starting to come down with a bug. (Sidenote, it's also really obvious to tell if you were drinking the night before because boy, does that hammer your HRV and therefore your Biocharge.) You can use the Zepp app and your Helio strap to track exercise and other activities - I run, swim, and cycle and you just use the app to start tracking and the phone does the GPS work while the strap feeds back your exertion, heart rate, and so on. Or, you can pair it with one of Amazfit's brilliant watches for when you are doing exercise (which is what I do - I know, *I don't wear a screen on my wrist other than when I'm running or cycling...) and the watch and the strap will work in sync and then update the Zepp app afterwards. You don't even have to have your phone with you, if you're crazy and like to go running without it. It tracks your sleep well too and, while there's no subscription needed for the Helio Strap, you can opt to subscribe to their Aura package for more detailed sleep analysis for £79 a year. This is still cheaper than Whoop's basic annual subscription. When I bought my Helio, Amazfit offered me the Aura sub for £29 so I gave it a go - I cannot quite see what it's giving me over the basic stats it gives me anyway so I probably won't renew if they choose to charge £79 at the end of the year. Overall, if you - like me - don't like wearing a screen-based device on your wrist but do want some form of tracking, I think this product is fantastic. It does everything you need from a fitness tracker without being intrusive; the black strap is stylish enough to not look silly on your wrist and, while Amazfit have not yet got round to offering alternative strap colours on their online shop, there are plenty of other choices available online.

Okay, here are my two cents. I will start with the pros. - overall pretty comfy and battery lasts around 7 days. - First thing is it's a good tracker. I think sleep tracking has been accurate. Heart rate is good, blood oxygen level, HRV, so you get a lot of the stuff, and I think it's been pretty good. - The food tracking is quite good. You can take pictures and scan labels. That's been very good for tracking your calories. - I quite enjoy tracking workouts as well, so it has loads of different modes where you can track your activity and exertion levels, so that's good. - Overall, that exertion mode gives you a realistic, good idea of how you are exercising and performing. Cons - Bio charge scores and sleep scores are not that helpful. Apple health could give me 100 but helio would be 80. Bio charge also a bit pointless imo. The optimal standard set is a bit too lofty. - You have to start and end workouts. Automatic detection is not good apart from walking or running. Once you do start the workout, the data is much better. - Insights are not as good, it can give you a crap score but not much of an explanation If you are looking to explore wearables, this is a great place to start. I’ve improved consumption and sleep from this device. And for the price, it is really good

J'ai porté des montres connectées chaque jour pendant les 10 dernières années, Polar et Garmin pour les dernières marques. Puis j'en ai eu assez des écrans et des notifications permanentes. Je suis donc repassé à une montre mécanique tout en cherchant de quoi suivre mon activité. Le bracelet Helio Strap tient toutes ses promesses. Léger, efficace, et avec une application qui est une bonne surprise. Surtout, j'ai pu comparer les données en le portant en parallèle pendant 2 semaines et Amazfit n'a pas à rougir, au contraire. Un excellent point pour le suivi du sommeil qui est meilleur que celui de certaines grandes marques. N'attendez juste pas un suivi automatique des activités, c'est le point faible. Mais à ce prix, ce bracelet écrase les autres fournisseurs. Sans rien envoyer sur internet,au passage. Ma femme a un Whoop et a décidé de basculer sur l'helio aussi. Ça veut beaucoup dire.

Not sure what the fuzz is about this. I cannot compare with other devices because this is my first. In the app you get a sleep score, a biocharge score and a exertion %. My sleepscore is around 80 and, my biocharge is usually around 70 and my exertion is 100% on the days I do sports. But the scores are so vague, not sure what to do with them. I used it for 2 months now. Its probably a me problem but I dont see the benefit.

The amazfit gives good stats, its very detailed and it does the 24/7 tracking, you get in youre normal life the 10 days of battery. Its 100% on of the better deal, However compared to cheaper amazfit with screens you might you might consider that 2. The zepp app gives good details, little advices , sleep tracking and its top notch. If you want also Ai in it and sleeping music you need to pay some extra money. But all the normal stats and advices are conepltly open like for the normal watches. +Detailed +Design & battery + Amazfit app is nice and detailed +Super nice small charcher(since you only need it once in a while) + You get a mini small plastic cube...thats it. -You get a mini small plastic cube....thats it. -band is super comfortable material and seems to hold up very well but might feel on the cheaper side.

Fantastic product. Comfortable, tracks everything. App is amazing. Track your food calories. Love this product.

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.
