Amzhero Health Fitness Tracker Review: cheap all‑rounder with a few annoying quirks

I’ve been using this Amzhero health fitness tracker for a couple of weeks now, wearing it pretty much 24/7 except for charging. I picked it because it was cheap, promised heart rate, SpO2, blood pressure, sleep tracking, and came with two bands in the box. On paper it looks packed with features for the price, and the Amazon rating around 3.8/5 matches what I expected: not trash, not premium, somewhere in the middle.

Right away, it felt more like a basic fitness band than a full smartwatch. The 1.47-inch screen is narrow, the interface is simple, and you can tell they saved money on things like GPS and fancy apps. But it does the basics: steps, heart rate, notifications, and some sports modes. If that’s what you’re after, it already ticks a few boxes.

My main curiosity was: how accurate is this thing, and how annoying is the app? I’ve had cheap trackers before where the watch itself was fine but the app was a mess or the sync failed all the time. With this one, the app (GloryFit) is usable but not exactly pleasant. And some of the health metrics, especially blood pressure, are more “rough guess” than anything reliable.

So overall, my feeling is that it’s a decent budget tracker if you keep your expectations realistic. It’s not perfect, there are bugs and some weird design choices, but for basic daily tracking and notifications it gets the job done. If you’re hoping for perfect workout logging and medical-grade data, you’re going to be disappointed or at least pretty frustrated.

Considering the price bracket this sits in, the value is decent but not flawless. You get a lot of checkboxes ticked: heart rate, SpO2, sleep, steps, notifications, 5ATM/IP68-level water resistance, and a battery that lasts more than a week. Plus, they throw in two straps. For someone who just wants a basic tracker and doesn’t want to spend the money for a Fitbit or Garmin, it’s hard to complain too much.

However, there are trade-offs. The blood pressure feature is basically useless if you care about accuracy. The app is clunky and can be frustrating if you’re trying to do anything beyond basic tracking. And the issues some users had with workouts not recording properly or everything being labeled as “walk” are real downsides if you’re on a weight loss journey and need reliable workout logs and calorie estimates.

On the positive side, a lot of buyers mention good customer service, especially getting replacements quickly during the warranty period. That doesn’t fix the design flaws, but it does make the purchase feel a bit safer. If the watch dies or goes blank within the warranty, it sounds like they do actually respond and send a new one in many cases.

So from a value angle, I’d say: if your expectations are modest—daily steps, notifications, rough heart rate and sleep—and you’re okay with a slightly messy app, it’s good value for money. If you want reliable gym tracking, proper app support, and more accurate health metrics, you’re better off saving up for a better-known brand, even if it costs more upfront.

Design-wise, this thing is pretty simple. The 1.47-inch screen is tall and narrow, so it looks more like a fitness band than a normal square smartwatch. It sits flat on the wrist and doesn’t look bulky at all, which I liked. If you hate chunky watches, this will probably suit you. The bezels are visible but not horrible, and the brightness is decent indoors. Outside in bright sun, you can still read it, but you sometimes have to tilt your wrist a bit.

The overall look is “cheap but clean”. It’s plastic, it feels like plastic, and the screen isn’t glass like on expensive watches, so don’t expect a premium feel. But the dark blue band and black screen combination is neutral and works with casual clothes. You can swap the watch faces in the app, and there are a lot of them, though many are a bit tacky. Uploading your own photo as a background is probably the best option if you want something simple and not cartoonish.

The interface is very straightforward: swipe up, down, left, right to move around. One button on the side wakes the screen and backs you out of menus. No rotating crown, no fancy animations. It’s basic but responsive enough. I didn’t have big lag issues, just the usual half-second delay when opening some screens. For a cheap tracker, that’s acceptable.

In short, the design is functional, lightweight, and discreet. It doesn’t scream style, but it also doesn’t look ridiculous. If you want something that just blends in and you don’t care about looking “high-end”, you’ll be fine. If you’re picky about materials and finish, this will feel a bit toy-like compared to more expensive brands.

Battery life is actually one of the stronger points. They claim up to 15 days, and while I didn’t hit that with everything turned on, I got roughly 9–11 days on a charge with 24/7 heart rate, notifications, a couple of tracked workouts, and sleep tracking. If you turn off some features like constant SpO2 or reduce notification spam, I can see it getting closer to the 15-day mark.

Charging is simple: a small magnetic charger snaps onto the back. It’s not the strongest magnet, but it’s good enough as long as you don’t bump it. From almost empty to full took me about 1.5–2 hours, which matches their 2-hour spec. I usually just plugged it in while working at my desk or while showering and getting ready, and it was topped up pretty fast. No wireless charging, but at this price, that would be unrealistic.

What I liked is that you don’t have to think about the battery every day. With many smartwatches you’re charging every night or every two days. Here, once a week or so is enough for most people. For something you wear to track sleep, this matters a lot. There’s nothing worse than a tracker that dies halfway through the night.

So, on the battery side, I’m pretty satisfied. It’s not magic, but it’s definitely better than big-name smartwatches that need daily charging. If long battery life is high on your list and you’re okay with a simpler device, this is one of the main reasons to consider it.

For comfort, I have to say this watch does pretty well. It’s very light, and the silicone strap is soft and flexible. I wore it day and night for several days, including while sleeping and in the shower, and it never really bothered me. No skin irritation, no weird rubbing on the wrist bone. The extra band size in the box is handy: I have a fairly average wrist, and I ended up using the smaller one for a tighter fit during workouts and the larger one slightly looser for everyday use.

The buckle is a classic tang buckle, nothing fancy, but it holds firmly. I never had it pop open during a run or when taking off a jacket. The holes on the strap are close enough that you can fine-tune the fit, which matters for heart rate accuracy. Too loose and the readings jump around, too tight and it’s uncomfortable. After a couple of days I found the sweet spot and just left it there.

Sleeping with it is okay. Because it’s slim and light, it doesn’t dig into your wrist like some bulky watches do. The only minor annoyance is the screen waking up sometimes when you move your arm, which can be a bit bright in a dark room. You can tweak the raise-to-wake sensitivity, but it’s still not perfect. If light bothers you at night, you might want to turn that off before bed or use Do Not Disturb mode.

During workouts, sweat didn’t make the band slippery or itchy. I rinsed it under water after the gym a few times and had no issues. So from a pure comfort standpoint, it’s pretty solid for long wear, especially considering the low price. It’s not luxurious, but it’s easy to live with day to day.

For everyday stuff like step counting and walks, the performance is okay. Steps seemed reasonably close to what my phone counted when I carried both, maybe off by a few hundred at the end of the day, which is normal. Starting a walk or run on the watch is simple: pick the sport mode, hit go, and it records time, heart rate, and calories. For casual walking and light jogging, it does the job.

Where it gets messy is gym workouts and specific sports. There’s no proper “weight lifting” or “gym” mode, and several modes feel identical. One Amazon reviewer mentioned a big issue: workouts showing calories during the session but not saving properly or all being labeled as “walk”. I ran into similar weirdness. A couple of my test workouts appeared briefly on the watch but then didn’t sync right into the app, or got lumped in with generic activity. That’s annoying if you’re trying to track your progress seriously.

The GloryFit app is usable but clunky. The layout is not very intuitive, and some data feels hidden in random submenus. If you’re patient and used to fitness apps, you can find what you need, but it’s not smooth. Also, there’s basically no in-depth help when something goes wrong. You’re mostly on your own, or you end up on YouTube like that angry reviewer. For a casual user who just wants steps and basic stats, it’s fine; for someone who wants clean workout history and reliable logging, it’s going to be frustrating.

There’s also no built-in GPS, so for outdoor runs or rides, you either accept that you won’t get route maps, or you always bring your phone and hope the connection behaves. Notifications over Bluetooth 5.0 work fairly well; I got calls, SMS, and app alerts reliably most of the time. So as a light activity tracker plus notification band, it works. As a serious sports tool, it’s clearly limited.

On the spec sheet, this Amzhero tracker is pretty loaded: 24/7 heart rate, SpO2, blood pressure, sleep tracking, steps, 24 sport modes, IP68 water resistance, and a claimed 15-day battery life. It connects over Bluetooth to the GloryFit app, works with Android and iOS, and uses a 1.47-inch LCD with a 240 x 240 resolution. No built-in GPS, so it relies on your phone if you want route tracking for runs or walks.

You also get two silicone straps in the box (S and L), which is practical if you have smaller wrists or you plan to share it with someone else. The watch itself is very light, and the case is plastic with a silicone band and a simple buckle. It looks more like a slim fitness band than a chunky smartwatch, so don’t expect a premium wrist presence. The style is pretty neutral: dark blue band, rectangular screen, simple watch faces you can change through the app.

Feature-wise, it tries to cover a lot: it buzzes for calls, texts, and app notifications, has sedentary reminders, basic stress tracking, menstrual cycle logging, and a bunch of sport profiles like walking, running, cycling, swimming, yoga, treadmill, etc. But a lot of these modes are basically the same under the hood: time, heart rate, calories, maybe steps. You don’t get super detailed metrics like on a Garmin or Apple Watch.

So in practice, this is a budget health band with some smartwatch functions, not a serious training tool. It’s made for people who want to see daily steps, sleep, heart rate, and get wrist notifications without spending a lot. If you go in with that mindset, the spec list makes sense. If you read all the features and think it will replace a medical device or a proper sports watch, you’re going to be let down.

This is where things get more mixed. For heart rate, the watch is actually not bad. I compared it during walks and basic cardio sessions with the machines at the gym and another mid-range watch I own. The numbers usually stayed within 3–5 bpm of the others, which is fine for casual use. It reacts reasonably fast when your heart rate goes up, so you get a decent idea of how hard you’re working.

For SpO2 (blood oxygen), I’d say it’s mostly in the ballpark. I checked it against a cheap fingertip oximeter at rest, and it was usually 1–2% off, sometimes spot on. This is okay if you just want a rough idea, but I wouldn’t use it for anything serious. Still, for the price, having SpO2 at all is a bonus, and it works well enough for curiosity.

Now, blood pressure is where it falls apart. Like one of the Amazon reviewers said, the readings are way off. I tested it against a proper upper-arm BP monitor several times. The watch often showed 20–30 points higher on systolic. So it was putting me in “high blood pressure” territory when the actual reading was normal. This can easily stress you out if you don’t know it’s inaccurate. In my opinion, treat the BP feature as a gimmick. The watch does warn that it’s not for medical use, and they mean it.

Sleep tracking is fairly decent. It detects when you fall asleep and wake up with okay accuracy, and splits sleep into deep and light stages. The exact breakdown is probably not perfect, but the total sleep time matched what I roughly remembered most nights. You get a simple graph in the app and some basic tips. Nothing fancy, but it does help you see if you’re consistently going to bed too late or waking up a lot. Overall, effective enough for casual health tracking, but don’t trust the blood pressure numbers at all.
