Sometimes you buy something cheap just to see what it’s like, and every once in a while, it surprises you. That was the case with the Blackview R50Pro. I grabbed it during a sale for just $19.98, and honestly, it hasn’t left my wrist since.

This isn’t just a bare-bones step counter with a screen. The R50Pro is a full-featured smartwatch with Bluetooth calling, over 100 fitness modes, SpO₂ and heart-rate monitoring, a bright color display, and solid battery life. For under $20, that’s not just rare—it’s almost unheard of.

The first thing you’ll notice is the display. It’s a 1.85-inch TFT touchscreen, and while it’s not AMOLED, it’s colorful and surprisingly sharp for the price. The resolution is 386×320 pixels, which gives it a respectable 271 PPI—clear enough to read texts, notifications, and health stats at a glance.

The watch is powered by a Realtek RT8763EWE processor, which handles day-to-day use without feeling sluggish. Navigation is smooth—swipe up for quick settings, swipe down for messages, and side-swipe through your steps, heart rate, and more.

You get all the expected smartwatch basics:

• Bluetooth 5.3 connectivity
• Music controls
• Call notifications and Bluetooth calling support
• Heart rate monitoring
• SpO₂ blood oxygen tracking
• Sleep tracking
• Step and calorie counting
• Stress tracking
• Women’s health calendar
• 100+ sport modes
• IP68 water resistance

I know that sounds like a lot—because it is. You’d be hard-pressed to find this much functionality even in a smartwatch that costs three times as much.

When I strapped the R50Pro on for the first time, I didn’t have high expectations. I figured I’d test it for a couple of days and toss it in a drawer with the other “too cheap to be useful” gadgets I’ve tried. Instead, I’ve actually kept wearing it.

It’s lightweight—noticeably lighter than my Galaxy Watch—and the included silicone strap is soft and flexible. I wore it while working out, walking the dog, and even during sleep to test the sleep tracking features. It never felt bulky or got in the way.

The UI is simple and intuitive, with large icons and smooth scrolling. You can customize the watch face from a selection in the companion app, or even use your own photo. While the brightness won’t compete with flagship smartwatches outdoors in direct sunlight, it’s more than enough for most environments.

Here’s where I was really surprised. You can make and take calls directly from the watch as long as it’s connected to your phone via Bluetooth. I tested this feature multiple times—answering calls while cooking or out walking—and the sound quality is clear on both ends. It won’t replace your phone, but it’s great for quick chats when your hands are full.

For the price, the health features are solid. The heart rate and SpO₂ readings were generally consistent with those from my more expensive devices. I wouldn’t rely on it for medical-grade accuracy, but it’s useful for casual health monitoring.

The watch tracks steps, calories, and even stress levels. The 100+ sport modes are more for categorization than precision data, but it’s nice to log different activities like yoga, cycling, and strength training with ease.

Battery life was another pleasant surprise. I got nearly 5 days of use on a single charge, including daily workouts, sleep tracking, and Bluetooth notifications. It uses a magnetic charging dock and tops up fully in around 2 hours. For something this inexpensive, that kind of battery life is a huge win.

Of course, it’s not perfect. You don’t get third-party app support, there’s no onboard GPS, and the display doesn’t have the deep blacks or responsiveness of an AMOLED screen. But honestly, none of that feels like a dealbreaker—because this is a $20 smartwatch.

If anything, its simplicity is part of the charm. There’s no app bloat, no unnecessary complexity. It’s just a smartwatch that does exactly what you want at a fraction of the price.

Who should buy the Blackview R50Pro:

• Anyone on a budget who still wants smartwatch features like fitness tracking, call support, and notifications.
• First-time smartwatch users who want to test the waters before investing in something more expensive.
• People looking for a backup watch for workouts, travel, or rough environments.
• Gift shoppers who want to give something cool and useful without spending a fortune.

I’ve reviewed and tested plenty of smartwatches over the years, from premium brands like Apple and Samsung to lesser-known budget models. The Blackview R50Pro is easily one of the best values I’ve come across. It’s not trying to replace your phone or blow your mind with cutting-edge features—it just does the basics really well, and at an unbeatable price.

At the regular $29.99, I’d already say it’s a good deal. But at $19.98, it’s one of the best impulse tech buys you can make right now. If you're even mildly curious about smartwatches, or you’re shopping for a practical gift under $25, the Blackview R50Pro is an easy yes.

And yes—I tested it myself, wore it for several days, made phone calls, tracked workouts, and even slept with it on. This isn’t just a cheap gadget. It’s a surprisingly capable, genuinely useful piece of tech that I’d recommend to anyone.
