; He haylou RS3 It is a smartwatch that seeks to offer everything necessary for monitoring health and fitness life in exchange for a very affordable price, but does it live up to what it promises? It’s time to find out.

We can anticipate that the RS3 boasts an AMOLED HD screen with many customization options for the sphere, and at the health care level it consists of blood oxygen monitoring and 14 sports modes as strong points.

Likewise, one of its great assets is GPS satellite positioning, something that we definitely do not see every day in this price range and the same can be said of its autonomy of up to 21 days, but that is not all, since it also consists of water resistance for swimming. For more details we invite you to continue reading.

Design and screen

The design of the Haylou RS3 is attractive. It looks like a premium watch. It has a large round screen, two-sided buttons, and a black metal case. It undeniably looks a lot like Haylou RT2 that we analyzed the other day, but the RS3 bets on more functions of a sporting nature than the RT2, so that’s the difference.

We can praise the build quality of the watch, as the screen has good glass protection and the frame has a rigid aluminum construction It provides structural integrity. One of the side buttons is just an on/off control for the screen display. It can be rotated, but that doesn’t scroll in the menus.

In this order of ideas, it is a light wearables and It has 22mm silicone straps. fully replaceable.

For its part, the screen has a thick border, so the actual panel is much smaller, only 1.2 inches to be precise. Going into details, it is a circular AMOLED panel with 390 x 390 pixel resolution, so the image is sharp and with a good level of brightness. However, despite being AMOLED type, it does not support the Always-On-Display function (screen always on) and that is a shame because an extraordinary device in this segment would have done it.

To close this section with a flourish, we must note that the Haylou RS3 has 5ATM water resistancewhich means that it can be submerged up to 50 meters deep for a few minutes and still work.

functions and features

On a basic level, the Haylou RS3 can track calories burned, steps taken, and distance covered during a workout, while also measuring the user’s heart rate accurately, or at least as accurately as can be expected from a product of this type, well remember that after all they are not medical devices. With that said, the watch also consists of blood oxygen monitoring (SpO2) and apparently it works correctly.

On the other hand, the sleep monitor leaves something to be desired; several users of this watch agree that it is not accurate, for example, we can wake up at 6am, but for some reason the watch will register it as if we had woken up an hour later and with that slip it is impossible to trust its measurement on the deep sleep. To make matters worse, it seems that the clock does not register the naps.

In another order of ideas, this is a totally recommended watch for sports or exercise, because supports 14 training modesincluding jogging, rowing, treadmill, mountaineering and swimming both in the pool and in open water, which makes that 5ATM certification valid. In these scenarios, the measurement works correctly, but the amount of statistics that the watch records is not as detailed as in luxury smartwatches.

Haylou RS3 - Features

With all that in mind, what separates the Haylou RS3 from other watches in this price range is the presence of GPSwhich allows us to track our routes with relative precision, and we say relative since it is not a high-end GPS chip.


Other functions present in the watch are: sedentary reminder, breathing exercises, remote notifications and mobile music control.

The app for this company’s watches is called Haylou Fun, and contrary to what the name indicates, there is nothing fun about it, because just a walk through the App page in the Google Play Store will tell us everything. what we have to know. In this sense, more than one user complains about problems using the appspecifically with features that don’t work as they should, involuntary unbindings, bugs and translation errors, not to mention that it consumes a lot of resources when running on mobile.

Although these problems are not inherent to the device itself, it is time to subtract points for being the accompanying software that Haylou recommends. That being said, in theory the app allows us to see a more detailed summary of all our statisticsas well as planning goals, checking the quality of our sleep and the route of our trips using GPS.


To conclude the tour of the characteristics of the Haylou RS3, we can say that it has an exceptional battery life, it is only 230mAh, but even so promises 12 days of daily use and up to 21 in basic mode.

In a more realistic use case and with occasional use of GPS, an average of 7 days awaits us. However, with GPS active at all times we can expect at most 21 hours, which is still acceptable given the price of the RS3.

Availability and price of the Haylou RS3
