Haylou Solar Pro has an impressive water resistance rating of 2ATM. But what does this rating mean, and why is it significant? The “ATM” rating is a measure of a device’s water resistance, with each ATM representing 10 meters of water pressure. In the case of the Watch R8, the 2ATM rating implies that it can withstand water pressures equivalent to a depth of 20 meters. To put this in perspective, this level of water resistance is more than sufficient for most water-related activities that individuals engage in.

So, there’s no need to worry about taking off your smart band before getting wet. Its 2ATM water resistance ensures that it can handle the rigors of swimming with ease. Beyond swimming, the Band water resistance extends to everyday scenarios where your smart band might encounter splashes, rain, or accidental spills.

But, given that the watch features a speaker and a microphone, it’s advisable to err on the side of caution and avoid exposing it to water whenever possible. While the Solar Pro is designed to be water-resistant, it’s essential to remember that water resistance does have limitations. The device is not intended for use in high-pressure environments such as scuba diving or in saltwater, as salt can be corrosive. Additionally, exposure to hot water or steam may compromise the device’s water resistance over time. To maintain the longevity of your smart band’s water resistance, it’s advisable to rinse it with fresh water and dry it thoroughly after exposure to seawater or chlorinated pool water.

Display Quality

Haylou has invested heavily in the most important aspect of the smartwatch which is the amazing display quality, I am happy to say that I was completely impressed with its display on the Haylou Solar Pro. When I first turned on the watch, I was immediately greeted with vividly saturated colors and deep shades of black. I was shocked because this is a display offered on an under $35 smartwatch.

Haylou Solar Pro LS18 Review: New AffordableĀ Smartwatch

The watch boasts a 1.43-inch AMOLED display with a resolution of 466×466 pixels and a high refresh rate, resulting in a smoother and more responsive user experience that sets it apart from many other budget smartwatches that often feature lower refresh rates. This display occupies a large part of the watch’s front surface, which is notably larger than most competitors in its category. It offers a level of screen real estate that’s not often seen in smartwatches of its class. The screen is flat, without the 2.5D glass found in previous Haylou smartwatches, but it compensates with a tactical-looking frame that adds to its overall visual appeal.

Moreover, the display quality is top-notch. Thanks to its high resolution and AMOLED technology, the colors are vibrant, the text is crisp, and everything appears exceptionally smooth, with the ability to produce deep blacks and high contrast.

Unfortunately, the Smartwatch does not have an auto-brightness feature, but considering its affordable price of $35, it’s understandable. However, the Solar Pro performs well in outdoor conditions thanks to its AMOLED display.

Multi Watch Faces

Watch faces are more than just a way to tell time. The Haylou Solar Pro comes with a stunning AMOLED screen, which serves as a canvas for a wide array of watch faces. With over 150+ watch faces to choose from on the App and some are built into the watch, there’s something for everyone.

With such a wealth of options, you’ll undoubtedly find the perfect watch face to match your mood and outfit.

Always-On Display

The Solar Pro doesn’t just stop at its remarkable display quality; it also introduces the convenience of an Always-On Display (AOD) which is a feature that keeps a portion of the screen active even when the watch is on standby mode to quick access to information without having to raise your wrist or tap the screen. With AOD enabled, a part of the watch face remains visible at all times, which means that even in standby mode, you can still check the time, date, and other essential details at a single glance.

Haylou Solar Pro LS18 Review: New AffordableĀ Smartwatch

One might wonder if keeping a part of the display active all the time would significantly impact battery life. However, the AOD in this watch is smartly designed to minimize battery consumption. It uses minimal power by dimming the display and ensuring that only the most crucial information is visible.

Sensor Performance and Accuracy

The Haylou Solar Pro offers several sensors to enhance its functionality. The heart rate sensor performs reasonably well during day-to-day activities, providing accurate readings. However, during intense workouts, it may struggle to keep up with rapid fluctuations in heart rate. It’s worth noting that the Solar Pro does not have a built-in GPS, relying on connected GPS from your smartphone for accurate distance and location tracking during outdoor activities.

Exercise and Health Tracking

The Haylou Solar Pro has comprehensive fitness and sports tracking capabilities which are equipped with a reliable pedometer that accurately tracks your steps throughout the day. It provides valuable insights into your daily activity levels, making it an excellent companion for those aiming to achieve their fitness goals. Additionally, the built-in sleep monitor helps you understand the quality of your rest. By analyzing your sleep patterns, it offers suggestions for improving your sleep quality, ensuring you wake up refreshed and ready to tackle the day.

Health-conscious individuals will appreciate the blood oxygen monitoring feature on the Solar Pro. This function allows you to measure your blood oxygen saturation levels, providing insights into your overall well-being. Monitoring your blood oxygen levels can be particularly valuable during workouts or high-altitude activities, helping you stay safe and optimize your performance.

The sensors are designed to provide users with comprehensive health tracking. These sensors monitor heart rate, oxygen levels, sleep patterns, and even stress levels. One notable feature is the sedentary reminder, which prompts wearers to stand up and move around, making it an essential feature for individuals leading predominantly sedentary lifestyles. However, it’s essential to keep in mind that, while convenient, relying solely on a budget device for health tracking may not be as accurate as dedicated medical devices or more expensive smartwatches.

While it may not have the same level of detail as high-end models, it still provides valuable insights into your workouts, such as heart rate monitoring and calorie tracking. The inclusion of these features ensures that you can monitor your progress and make informed decisions about your fitness goals.

Sports Modes

What truly sets the Haylou Solar Pro apart is its vast selection of sports modes. With over 100 different options to choose from, you’ll find a mode tailored to virtually any physical activity you enjoy. Whether you’re into running, cycling, swimming, or yoga, this smartwatch has you covered. The watch’s workout and running modes are especially noteworthy, offering specialized features for tracking outdoor activities with precision. The Solar Pro takes your fitness regimen to the next level by providing real-time data on your workouts. From monitoring your heart rate during high-intensity intervals to tracking your pace during a long run, this smartwatch ensures you stay on top of your fitness game.

Step counting, on the other hand, appears to be slightly underestimated when compared to dedicated step counters. The watch is generally consistent, but it might not keep up with the exact number of steps taken. Nevertheless, it provides a reasonable estimate for daily activity tracking. In addition to standard fitness tracking, the Solar Pro doubles as a personal trainer. While the accuracy of some metrics, particularly in activities like running, might be questioned, and offers trend analysis rather than pinpoint precision. For its price range, the wealth of health-related data provided by the Solar Pro surpasses expectations.

During activities such as running, the watch provides essential data like time, heart rate, pedometer, cadence, and calories burned. While the stress level monitoring function helps you keep track of your overall well-being. The Haylou Solar Pro also includes a breathing exercise feature, assisting users in managing stress and improving relaxation. A specific feature for women, the woman health or cycle feature, offers insights and tracking options related to menstrual cycles.

Haylou Fun App & Pairing

On the phone side, the work Haylou has done on the Haylou Fun app has been painstaking, though it reminds us of other Chinese companies and how they designed their fitness apps. If you have used an Amazfit or Huawei watch, this app will look very similar.
This can be easily found on the Apple Store and Play Store and is free. It is therefore simply necessary to open it, add the smartwatch, and wait for the entire configuration phase.

How To Pair The Haylou Solar Plus

Connecting the smartwatch to your phone is very simple:

  • Turn on the Bluetooth of the watch and mobile phone.
  • Click Add Device in the APP to connect the watch to the APP or scan a QR code on the watch.
  • While the permissions might seem extensive, they contribute to unlocking the full potential of the smartwatch.

How Haylou Fun App Works

Once all operations are completed, the various information detected by the wearable device will also be quickly reported on the APP. As in previous models, the user interface is easy to navigate, which at least from a graphic point of view is coherent and intuitive. In fact, from the main screen, we can instantly get an overview of our activities, as well as take a look at our heart rate, sleep monitoring, pressure, and body weight.

Haylou Watch R8 Review: A Budget Smartwatch at $35 with AMOLED Display And High-end feature

Set various heart rate monitoring options, enable notifications from different apps, set a reminder, and much more. Not only that but in addition to all the various information on the smartwatch itself, it is possible to display more data within each area on the main page of the application. By clicking on the heart rate square, for example, we immediately see the full graph for the day, with all the different measurements, as well as data on the average frequency, and maximum and minimum beats.

Furthermore, the watch supports data synchronization with popular third-party applications like Google Fit and Strava, ensuring seamless integration with your existing fitness ecosystem.

Notifications & Messages

Notifications on the Haylou Solar Pro arrive quickly and are clear and easily readable. And you won’t miss important messages or notifications. However, you cannot reply to messages. The watch syncs with your smartphone to display incoming calls, messages, social media (Facebook, WhatsApp, Twitter), and other app notifications, allowing you to stay connected even when you’re on the move.

Making and Receiving Calls

The Haylou Solar Pro stands out from the crowd by offering a seamless calling experience. While many smartwatches merely notify you of incoming calls, this watch takes it a step further ā€“ it allows you to answer your smartphone calls directly from your wrist. All you need to do is sync your smartphone with the watch via Bluetooth 5.3 and when a call comes in, a button will appear on the watch’s screen. Simply tap it to answer the call. What sets the Solar Pro apart is its integrated microphone and speaker. The microphone delivers remarkably clear sound, even in noisy environments like on the road, ensuring that your calls are audible and clear.

To enhance efficiency further, the smartwatch lets you save your important and frequently-called contacts, eliminating the need to sift through a lengthy contact list when you’re in a hurry. Additionally, it features a dial pad that enables you to make calls quickly and conveniently. With these calling capabilities, the Solar Pro offers a practical solution for staying connected while on the go.

Battery Life and Charging

Battery life is a crucial factor to consider when choosing a smartwatch, and the Haylou Solar Pro excels in this aspect. With regular usage, the smartwatch can last up to an impressive 20 days on a single charge. This extended battery life is a result of efficient power management and optimization. However, if you utilize the extensive sports and health features, such as continuous heart rate monitoring, the battery life reduces to approximately 7 days. Despite the slight decrease, the Solar Pro still outperforms many other smartwatches in its price range.

However, this is on paper but in reality, it may differ slightly since when fully charged, the watch barely managed to reach the end of the third day. This difference in endurance is mostly due to the always-on feature, which may have affected performance. When it’s time to recharge, the smartwatch can be fully charged from 0 to 100% in approximately 1 hour and 42 minutes, ensuring that you spend less time waiting and more time enjoying its features. Despite all this, I can say that the battery of the Solar Pro is impressive.
