Tensky ID208Plus Smart Watch Review: Cheap Alexa watch that covers the basics

I’ve been wearing this Tensky smartwatch every day for a few weeks now, paired with an Android phone, and I’ll be blunt: I bought it expecting a cheap toy and was ready to send it back. Instead, it ended up staying on my wrist full time, including at night and in the shower. It’s not perfect, there are some rough edges, but for the price, it does more than I thought it would.

My use is pretty simple: I want notifications, calls on the wrist, step tracking, sleep tracking, and something that doesn’t need charging every night. I’m not chasing ultra-precise training data like with a top-end Garmin or Apple Watch. I mainly wanted something that gets the job done for everyday health tracking and lets me leave the phone in my pocket during the day.

Right away, what stood out is the battery life and the comfort. I’ve had brand-name watches that cost three times more and still needed charging every 1–2 days. Here, I easily get close to a week with calls, heart rate monitoring and sleep tracking on. The app (VeryFit) is pretty basic, but it syncs reliably enough and I didn’t have to fight with it every day, which is already a win.

If you expect the polish of an Apple Watch or Samsung Galaxy Watch, you’re going to see the limits: the screen isn’t as sharp as advertised in the listing, Alexa is a bit picky, and the microphone is just okay. But if you’re looking for a cheap all-rounder that tracks your health, lets you answer calls, and doesn’t feel like a brick on your wrist, this one is honestly not bad at all.

For me, the main argument for this Tensky watch is the price versus what you get. You’re getting: Bluetooth calls, notifications, heart rate, SpO2, sleep tracking, stress tracking, 120 sports modes (even if most are generic), Alexa integration, decent battery life, and water resistance, all for what is usually a budget price bracket. Compared to a Fitbit or an Apple Watch, you’re obviously losing a lot of polish and advanced features, but you’re also paying a fraction of the price.

In daily use, it covers almost everything a casual user needs: checking who’s calling, seeing messages without grabbing the phone, tracking your steps and sleep, and monitoring basic heart rate trends. If that’s your level of expectation, the value is pretty strong. You’re not paying for fancy materials or a big brand name, just for a straightforward device that does the basics reasonably well.

On the downside, you feel the budget side in a few places: the app is basic and sometimes a bit clunky, Alexa support is not as smooth as on big-brand devices, and the mic/speaker combo is okay but not great. Also, the whole “120 sports modes” thing is more a marketing bullet than something you’ll really use in detail. But for the price, I can live with that. The main thing is that the watch is reliable enough and doesn’t feel like it’s going to fall apart in three months.

If you’re coming from a high-end smartwatch, you’ll probably find it a bit “meh” and limited. If this is your first smartwatch or you just want a cheap replacement to track your health and get notifications, it’s actually good value for money. You’re not getting luxury, but you’re getting a solid little gadget that does what most people need without draining your bank account.

Visually, this watch is straightforward: rectangular case, black silicone strap, and a single side button. No fancy metal bezel or premium vibe, but it doesn’t look toy-like either. On the wrist, it’s closer to a basic Fitbit or an older Apple Watch look than a high-end fashion accessory. If you want something flashy, this isn’t it. If you want something that blends in and doesn’t scream “cheap gadget”, it does the job.

The screen is 1.8" with a 240 x 280 resolution (ignore the 320 x 385 claim in the description, that’s not what the specs say). In real use, the screen is bright enough and readable outdoors unless you’re in direct strong sun, where you sometimes need to tilt your wrist to see better. The colors are decent, not washed out, but you can tell it’s not an OLED. The touch response is good; I didn’t have to stab the screen three times to open a menu, which is often a problem on very cheap watches.

What I liked is the amount of watch faces available in the app. There are plenty of simple designs (digital, analog, more sporty, more minimal), and you can also put your own photo as a background. I used a picture of my dog, and it took less than a minute to set up. Some faces are a bit tacky, but there are enough normal ones to find something that doesn’t look childish.

In terms of size, it worked fine on my medium wrist and also looked okay on a smaller wrist when my partner tried it. It’s not excessively thick, so it slides under a shirt cuff without a problem. The bezels are visible, so don’t expect a borderless screen effect. But overall, design is simple, neutral, and practical. It’s not a style statement, but it doesn’t look like a toy watch from a supermarket bargain bin either.

The battery is honestly one of the best parts of this watch. Tensky claims about 8 days, and in my real use I got between 6 and 9 days depending on how much I played with it. With 24/7 heart rate on, sleep tracking, around 30–40 notifications a day, a few short calls through the watch, and screen brightness on medium, I usually ended up charging it once a week. For a watch that handles calls and has a color screen, that’s pretty solid.

When I turned off always-on heart rate, cut down on some notifications, and used it more as a simple watch + step counter, I pushed it close to 9 days. On the flip side, on a week where I messed around with the watch faces, used Alexa a few times, and did longer workouts with connected GPS via the phone, it dropped closer to 5–6 days. Still, even in the worst case, it’s far from the daily charging routine of some big-name smartwatches.

Charging is done with the small magnetic cable in the box. It snaps on easily enough but you do need to place it correctly; if you just throw it on the table you might think it’s charging when it’s not, so just double-check the icon on the screen. Going from around 10% to 100% took me roughly 1.5–2 hours, which matches the stated 2-hour charge time. Not blazing fast, but you’re doing this once a week, so it’s not a huge deal.

In everyday life, not having to think about the battery all the time is a relief. I charged it while working at my desk or while watching TV, and it was good to go for several days. If you’re coming from an Apple Watch that you have to plug in almost daily, this feels pretty comfortable, even if the watch is more basic in other areas.

Comfort-wise, this is where the Tensky watch surprised me in a good way. The watch is pretty light (around 90 g with everything, and it feels lighter on the wrist than that number suggests). I wore it 24/7 for several days, including at night, and it didn’t bother me. I’ve had bulkier smartwatches that I ended up taking off for sleep because they dug into my wrist or felt like a brick. This one, after a while, you just forget it’s there.

The silicone strap is basic but soft. It didn’t irritate my skin, even when I wore it during workouts and it got sweaty. The standard buckle is simple and reliable, and the strap has enough adjustment holes for thin and thicker wrists. The inner side is smooth, no sharp edges or weird bumps. I did notice that if you wear it very tight for heart rate accuracy, you might get a small mark on your skin, but that’s normal and not specific to this model.

For sleep tracking, I’m picky: if a watch is too big or the strap too stiff, I take it off in the middle of the night. Here, I kept it on without thinking about it. The watch doesn’t move around too much, and the sensors on the underside don’t stick out in an annoying way. I only really noticed it when I slept on the same wrist and put pressure on it, but again, that’s true for most watches.

In daily life (typing on a keyboard, driving, doing dishes), it stays out of the way. It’s water-resistant enough that I didn’t bother taking it off for showers or washing my hands. Overall, comfort is one of the strong points: not luxurious, but very decent, and you can genuinely wear it all day and night without it becoming annoying.

After a few weeks of daily use, including showers, washing dishes, and a few swims, the watch still looks basically new. The 3ATM / IP68 water resistance seems legit for everyday life. I wore it in the pool for short sessions, and it handled it without any drama. I wouldn’t go deep diving or abuse it in salt water without rinsing, but for swimming, rain, and showering, it’s been fine so far.

The case is plastic, which has pros and cons. On the plus side, it keeps the weight down and doesn’t get cold like metal. On the downside, it doesn’t feel as premium and if you slam it against a metal doorframe, it will probably mark faster than a metal case. I bumped it a few times on desks and door handles, and I don’t see any big scratches yet, just some very light marks you only notice if you look closely.

The screen is not sapphire or anything fancy; it’s standard glass. I’ve been reasonably careful but not obsessive, and I haven’t picked up obvious scratches yet. If you’re clumsy or work in a rough environment, I’d consider putting a cheap screen protector on it, just for peace of mind. The strap has held up well: no cracking, no peeling, and the buckle still feels solid. If it does wear out, it’s a standard-style strap, so it’s easy enough to replace with another 22 mm silicone or nylon band.

Overall, durability feels in line with the price. It’s not built like a tank, but it’s tough enough for normal day-to-day use, workouts, and water exposure. If you bash it around constantly, you’ll see the limits of plastic, but for most people using it as a daily fitness and notification watch, it should hold up just fine.

Let’s talk about what most people care about: how well it tracks and how the smart features behave. For steps and general activity, it’s in the right ballpark. Compared to my phone and another mid-range smartwatch, the daily step count was usually within 5–10% difference, which is acceptable for casual tracking. If you’re not training for the Olympics and just want to know if you moved enough during the day, it’s fine.

For heart rate, it’s okay at rest and during light to moderate exercise. When I sat on the couch or walked, the readings matched pretty closely with a chest strap and another watch. During more intense workouts with lots of arm movement (HIIT, indoor cycling), it sometimes lagged or gave slightly lower peaks. That’s common on optical sensors in this price range. SpO2 measurements were consistent with a cheap finger oximeter I have, but I wouldn’t make medical decisions based on it.

The sleep tracking is one of the things I found the most useful. It detects roughly when I fall asleep and wake up, and splits sleep into light, deep, and awake periods. It’s not ultra-precise, but when I had a bad night, the graph clearly showed it. The app gives a simple summary with total sleep time, time to fall asleep, and some basic advice. It’s nothing advanced, but it’s enough to see patterns like “I go to bed too late” or “I wake up a lot on certain nights”.

On the smart side, notifications come through quickly as long as the phone is within Bluetooth range. If I left my phone upstairs and walked downstairs, I’d sometimes lose connection, just like that Amazon reviewer mentioned. The Bluetooth range is pretty standard; don’t expect miracles through thick walls. Calls worked fine in quiet environments; in noisy places, the mic struggles a bit, and I had to raise my voice. Overall, performance is decent but not spectacular: it covers the basics well, with some small compromises you’d expect at this price.

On paper, the Tensky ID208Plus throws a lot of numbers at you: 1.8" screen, 120 sports modes, heart rate, SpO2, stress, sleep tracking, Alexa built-in, Bluetooth calling, 3ATM/IP68 water resistance, 350 mAh battery, and a claimed 8 days of battery life. In practice, I’d say it delivers a good chunk of that, but some features are more marketing than daily use.

The basic stuff works well: notifications, step counting, heart rate, sleep tracking, and call handling. I get WhatsApp, SMS, calls, and app alerts on my wrist without having to constantly check my phone. You can’t reply properly to messages from the watch (no keyboard or real quick replies on my setup), but for reading and screening calls, it’s very handy. The call function is simple: Bluetooth connection to the phone, built-in speaker and mic on the watch. I used it in the car and at home, and people could hear me as long as I wasn’t too far from my mouth.

The famous “120 sports modes” is basically a huge list where, in reality, the watch always tracks more or less the same metrics: time, heart rate, calories, distance (via the phone’s GPS for precision). For common activities like walking, running, cycling, or the gym, it’s fine. For more niche sports like kayaking or badminton, it’s mostly just a timer with heart rate. It’s good enough to log that you moved, but don’t expect detailed performance data.

Where it feels budget is on the software polish. The VeryFit app is functional but a bit dull. Graphs are simple, settings are scattered in menus that aren’t always obvious, and the Alexa integration is a bit clunky to set up. Still, once it’s configured, I didn’t have major disconnections or sync issues. For a cheap watch, the overall package is pretty solid and usable on a daily basis, as long as you keep your expectations realistic.
