Tensky Smart Watch for Women Review: a cheap Alexa watch that covers the basics

I’ve been using this Tensky smart watch for women for a bit now, mainly as a daily watch for steps, sleep, and quick notifications. I’m not a hardcore athlete, and I’m not married to any brand like Apple or Samsung. I just wanted something that counts steps, tracks sleep, lets me see who’s calling, and doesn’t die after one day. This one popped up a lot in the "under £50" range with a decent rating, so I gave it a go.

My expectations were pretty simple: it had to be comfortable enough to wear all day, survive showers and the odd swim, and not look like a toy. The Alexa thing and Bluetooth calling sounded nice, but honestly I saw them more as bonuses than must-haves. I’ve owned a couple of budget fitness bands before, so I roughly knew what to expect in terms of accuracy and build quality at this price point.

Out of the box, it feels like a classic budget smartwatch: light plastic body, silicone strap, and a bright rectangular screen. Setup with the VeryFit app took me around 10–15 minutes including firmware updates and notification settings. Not super slick like an Apple Watch, but nothing painful if you’ve ever paired a Bluetooth device before. Once it was paired, it synced steps and sleep data without drama.

Overall, my first impression was: pretty solid for the money, with a few rough edges. It does most of what it promises, but you can feel that it’s a budget product in some areas, especially the app and the Bluetooth range. If you’re expecting premium smartwatch behaviour, you’ll be annoyed. If you want something cheap that does the basics plus a bit more, it’s worth looking at.

For the price this Tensky watch usually sells at, I’d put it firmly in the “good value for money” category. You’re getting a colour touchscreen, heart rate, SpO2, sleep tracking, Bluetooth calling, Alexa integration, and a ton of sport modes in a device that looks decent and doesn’t feel like a brick. When you compare that to big-name brands where you pay several times more, it’s clear you’re trading some polish and accuracy for a much lower price tag.

Where the value shows is in the everyday basics: steps, sleep, notifications, quick calls, and general awareness of your activity. For that, it performs well enough that most casual users will be satisfied. You don’t need a subscription, the app is free, and the battery life means you’re not constantly searching for a charger. If your main goal is to keep an eye on your health metrics, get gentle nudges to move, and have a watch that plays nicely with both Android and iOS, it’s a solid deal.

On the flip side, there are some compromises. The app experience is clearly budget, the Bluetooth range isn’t great, Alexa integration feels a bit clunky and very phone-dependent, and the overall accuracy of the more advanced metrics (stress, exact sleep stages, etc.) shouldn’t be treated as medical data. If you’re serious about training or want deep GPS and performance analytics, you’re better off saving for a Garmin, Polar, or a higher-end smartwatch.

So, in simple terms: if you want a fashion accessory that also behaves like a full-blown smartwatch with top-tier software, this isn’t it. If you want a cheap, functional watch that covers the essentials and throws in some extra features like calls and Alexa for convenience, the value is hard to argue with. It’s not perfect, but for the price, it does more than enough.

Design-wise, this watch is clearly aimed at women, but it’s not over-the-top “girly” in a bad way. The pink version I tried is more of a soft pastel pink, not neon. The case is rectangular with rounded corners, very much in the generic smartwatch style, so it doesn’t scream cheap toy from a distance. It’s light on the wrist and doesn’t feel bulky, which I appreciate because some unisex smartwatches look like small bricks on smaller wrists.

The 1.8" screen is actually one of the stronger points. It’s bright enough to see outdoors on a normal cloudy day, and the 320×385 resolution is sharp for this price. Icons and text are clear, and touch response is pretty quick. You can tell it’s not on the same level as an Apple Watch or Samsung flagship in terms of smoothness, but for basic swiping through menus, it’s fine. I didn’t notice big lag or random freezes during normal use.

There’s one side button that acts as a home/back button and to wake the screen. The rest is all touchscreen. The bezels around the screen are there, but the watch faces are designed to blend them in decently, so they’re not too distracting. Speaking of watch faces, there are a lot of them: over 100 in the app, plus you can use your own photo. I ended up using a simple digital one with big numbers because some of the fancier ones looked a bit cluttered or childish.

On the downside, you can feel the plastic when you touch the case. It doesn’t feel premium, just standard hard plastic, and the overall look is more “practical gadget” than jewellery. If you want something that looks like a traditional watch with metal and glass, this isn’t it. But if you just want something that looks tidy, modern, and not too chunky on a smaller wrist, it does the job pretty well for the price.

The brand claims up to 8 days of battery life, and some users even talk about charging every few weeks. In my usage, reality sat in the middle. With always-on heart rate, regular notifications, a couple of short workouts tracked each week, and wearing it at night for sleep tracking, I was getting around 5–7 days per charge. That’s still much better than watches that need charging every night, but it’s not the three-week miracle some people dream of.

Charging itself is straightforward. The magnetic charger snaps onto the back of the watch and charges from 0 to 100% in about 2 hours, which matches the spec. The magnet is okay, not super strong, but as long as the watch is lying flat on a table it stays attached. I usually plugged it in while working at my desk or during a shower and breakfast session, and a short top-up gave me a couple more days easily.

Battery drain depends heavily on what you turn on. If you reduce screen brightness, shorten screen timeout, limit notifications, and maybe turn off 24/7 stress tracking, you’ll stretch the battery quite a bit. If you blast the brightness, leave all health tracking on, and take calls on the watch regularly, you’ll be closer to the lower end of that range. Alexa usage doesn’t seem to kill the battery instantly, but using voice features all the time obviously adds some drain.

Overall, battery life is one of its strong points for the price bracket. It’s not the kind of watch you need to baby-sit every day, and it fits well into a once-a-week charging routine. If you’re coming from an Apple Watch or similar, you’ll probably be pleasantly surprised. If you believed the most optimistic user reviews and expected to forget the charger for a month, you’ll be a bit disappointed. Realistically, a solid week is achievable for most people.

Comfort was actually one of the pleasant surprises. The silicone strap is soft and flexible, not the stiff rubbery type you sometimes get with cheap trackers. I wore it almost non-stop: during the day, at the gym, in the shower, and at night for sleep tracking. It never rubbed or caused any skin irritation, and the watch is light enough that I often forgot I had it on, especially after the first couple of days.

The standard pin-and-buckle closure is basic but works. There are enough holes to fit slimmer wrists without leaving a huge tail of strap flapping around. The watch stays in place during normal activity, walking, and light workouts. For more intense workouts like running or HIIT, it still stayed put, but if you wear it too loosely you’ll notice the sensor lose contact occasionally, which can mess with heart rate readings. That’s pretty standard for this type of device though.

For sleep, I’m usually quite picky; anything too heavy or bulky annoys me. With this one, after one or two nights, I stopped noticing it. The underside is smooth, the sensor area doesn’t dig into the skin, and the strap doesn’t cut into the wrist. The only minor annoyance is the screen lighting up if you move your wrist too much at night. You can tweak the “raise to wake” setting or turn on do-not-disturb to reduce that, but out of the box it did light up a few times while I was rolling over in bed.

In terms of wearing it in water, 3ATM / IP68 waterproofing held up fine for me in the shower and during swimming sessions. No moisture under the screen, no fogging, and no weird reactions to shampoo or soap. After swimming, the strap dries quickly and doesn’t get sticky. Overall, for daily comfort, I’d say it’s very decent: you can genuinely wear it 24/7 without feeling like you’re dragging around a brick, as long as you’re okay with the plastic look.

In terms of build quality, you can tell it’s mostly plastic, but that’s not automatically a bad thing. Plastic makes it light and less likely to shatter if you bump it. Over a few weeks of regular use – including workouts, showers, and some accidental knocks against door frames and desks – I didn’t see any cracks or serious marks on the case. The screen didn’t scratch easily, though I was not smashing it against metal equipment either. I’d still consider a basic screen protector if you’re clumsy.

The strap feels decent: soft silicone, no signs of tearing or stretching so far. The holes haven’t warped, and the buckle still holds firmly. If you sweat a lot or wear it tight, you’ll want to rinse the strap sometimes to avoid grime buildup, but that’s standard for any silicone band. Replacement straps should be easy to find since the attachment system looks pretty generic, though you may need to double-check sizes.

Water resistance has been reliable. It’s rated 3ATM/IP68, and I’ve worn it in the shower, washing dishes, and swimming without any issues. No fogging under the glass, no weird behaviour after being in water. Obviously, I wouldn’t take it deep-sea diving, but for day-to-day water exposure, it handles it fine. The charging contacts also haven’t corroded or discoloured with normal use.

One thing worth mentioning is the contrast between the official 365-day warranty in the specs and the “5-year guarantee” mentioned in the description. That’s a bit confusing. That said, several user reviews mention pretty responsive customer service when things go wrong, with replacements or refunds offered. I didn’t have a failure myself, but it’s reassuring to see that others had positive experiences with after-sales support. Overall, durability feels good for the price: not bulletproof, but solid enough if you’re not abusing it.

On the fitness and health side, the watch covers the usual things: steps, distance (based on your phone’s GPS or your stride), calories, heart rate, SpO2, stress, and sleep. Steps were reasonably close to what my phone and another fitness band showed, usually within a few hundred steps at the end of the day. It’s not lab-grade, but for getting a general idea of how active you are, it’s good enough. Heart rate during rest was consistent, and during workouts it followed the general trend, though it sometimes lagged a bit when I changed intensity quickly.

Sleep tracking is one of the features I actually liked. It automatically detected when I fell asleep and woke up, and the times were mostly on point, maybe off by 10–15 minutes sometimes. The app breaks it down into light, deep, and REM sleep, plus shows how often you woke up. I wouldn’t treat this as medical data, but it’s useful to spot patterns, like going to bed too late or waking up a lot during certain nights. The stress tracking is more of a gimmick for me; it’s basically based on heart rate variability, and the numbers jump around quite a bit.

On the smartwatch side, calls and notifications are the big ones. When the Bluetooth connection is solid, calls come through on the watch, and you can answer directly, thanks to the built-in mic and speaker. The sound is decent for short calls in a quiet room. In noisy places, it’s harder to hear, and the other person sometimes said I sounded a bit far away unless I held my wrist closer and spoke up. It’s handy for quick “I’m on my way” type calls, but I wouldn’t hold long conversations on it.

Notifications from WhatsApp, texts, and apps like Facebook or email show up quickly when you’re within range of your phone. You can’t reply in detail from the watch, but you can read enough to decide if you need to grab your phone. The main weak spot is the Bluetooth range: if your phone is in a locker or in another room with thick walls, the connection drops, and you’ll miss notifications until you’re back in range. That lines up with other user reviews. So, performance is solid when you’re near your phone, but don’t expect it to stay connected across a whole building.

In the box, it’s pretty barebones: you get the watch itself, a magnetic charging cable, and a small user manual. No spare straps, no fancy extras. The manual is short but clear enough to get you through pairing and the main features. I used it with an Android phone, and the watch requires the VeryFit app to do anything useful. Installation is straightforward, but you do need to grant a bunch of permissions if you want notifications, calls, and health data tracked properly.

The watch tries to tick a lot of boxes: Bluetooth calling, Alexa built-in, 120 sport modes, heart rate, SpO2, stress, sleep tracking, menstrual cycle reminders, plus notification mirroring. In practice, I’d say it nails the basics (steps, heart rate, sleep, calls, notifications) and the rest is more “nice to have” than genuinely useful. For example, those 120 sport modes are mostly variations of the same tracking with different names slapped on. If you’re a normal user, you’ll probably use walking, running, maybe cycling, and ignore the rest.

The VeryFit app is where you really feel the budget side. It works, but it’s not polished. The layout is a bit cluttered, some translations feel off, and it’s not as smooth or detailed as what you get from Fitbit or Garmin. Still, the basics are there: daily steps, distance, calories, heart rate graphs, sleep stages, and some simple stress data. Syncing is usually quick once the Bluetooth connection is stable, but if you move too far from your phone or disable Bluetooth to save battery, you’ll see delays or missed notifications.

Day to day, I used it mostly for: checking my step count, seeing who’s calling, reading quick WhatsApp and text previews, glancing at the time and weather, and tracking sleep automatically. For those things, it gets the job done. If you want deep training analytics or super accurate GPS tracking, this is not that kind of product. But as a basic smartwatch/fintess tracker hybrid that doesn’t cost as much as the phone in your pocket, it’s fairly convincing, with some quirks you need to accept.
