How practical are smartwatches? Do they just serve as notification screens, or are they serious health monitoring tools? How reliable are features like weekly activity goals, heart rate tracking, and sleep analysis? Are they genuinely useful for fitness tracking, or is it just a marketing gimmick?
Are smartwatches actually useful or just smart?

The practicality of smartwatches really depends on what you plan to use them for, of course. For most of us users, having notifications right on our wrists is a huge convenience, but some models can even track serious health data like heart rate, ECG, and sleep analysis. I’ve been using both Garmin and Apple Watch for a while now, and each one fits different needs depending on the situation. At least in terms of fitness tracking, I haven’t run into misleading heart rate data—the watches confirmed when I hit my daily movement goals.
That said, there are definitely some models out there that use health tracking as a marketing gimmick, especially in very cheap watches where calibration issues can pop up. But if you go for medical-grade options (like the ECG feature on the Apple Watch Series 8), the reliability is pretty solid. I actually got an alert from my watch when it detected a sudden spike in my heart rate, and after showing it to my doctor, we found out there wasn’t anything serious going on. So, if you pick a quality brand and set your expectations right, smartwatches aren’t just a stylish accessory—they can actually be a really useful tool.
Let's look at it objectively: with a budget of 80,000 rubles, it's still better to aim for solid "hardware," and the fitness gimmicks in watches are only good for basic tracking. What do you need them for specifically?
A year ago, I bought a smartwatch to track my daily movement, thinking it was just a toy at the time. To my surprise, it completely changed my exercise habits: the daily activity goals (10,000 steps, 30 minutes of moderate movement) keep me consistently active even on days without a workout plan.
What I find particularly helpful is the continuous heart rate monitoring during workouts. During my runs, the smartwatch was the first to show me how variable my pulse reacts under stress, which made me adjust my training intensity. However, I have to say the sleep analysis is quite rough. While the smartwatch does detect rough phases (deep sleep, REM), the exact percentages often differ from my actual sleep quality (tested against polysomnography data from a sleep lab in my circle of friends).
In the end, it’s not a replacement for medical devices, but as a tool for everyday life, it’s absolutely useful—as long as you understand that it provides guideline values. The 5-7 day battery life makes it my daily companion.
The practicality of smartwatches largely depends on what you intend to use them for, but the features we see in modern models do offer plenty of hands-on applications. For instance, the Apple Watch Series 8 can detect heart rhythm irregularities (AFib) with over 99% accuracy, backed by clinical studies. It uses green LEDs to track your pulse, measuring blood flow beneath the skin with laser-like precision. For sleep analysis, anti-fraud tech (like ensuring the watch stays on your wrist during measurements) kicks in—but results can still be misleading if you sleep with a mask on.
When it comes to fitness tracking, it’s wise to cross-check data rather than relying on a single source. Many users report step counts being inflated by 15-20%, likely because the watch misinterprets arm movements as "walking." On the other hand, VO₂ max measurements (which gauge endurance-related fatigue) align closely with lab results, boasting up to 90% accuracy. Apple’s Fitness+ integration takes it further by using motion capture to analyze workouts and offer personalized recommendations. So, if you’re not a serious athlete, it might feel like marketing fluff—but as a data collector and motivation tool, it gets the job done.
Six months ago, I was also wondering if it was worth buying one. In the end, I bought a cheap model and was surprised: the step count usually matches my phone, but the watch doesn’t work at all when swimming. My heart rate monitor sometimes shows weird readings when I walk fast—I trust a chest strap more for that. But the sleep analysis actually helped me recognize my restless sleep. Not perfect, but better than nothing!
