Why is the Apple watch so popular?

Apple Watch is one of the most expensive and yet the most sought after smartwatches on the market. This is due to several factors. First, the popularity and prestige of Apple as a manufacturer of high-tech products. The price is ultimately offset by the durability and reliability of the device, with long service life.

Second, the watchOS operating system, like iOS on the iPhone or the Macbook and iMac operating system, also has its say. These operating systems make every new development from Apple trust millions of users around the world. In addition, it is compatible with all brand products; welcome to all who use Apple.

How is the Apple Watch different from other smartwatches?

From the point of view of the structure and aesthetics of the watch, it is made of first-class materials and highly stylized coatings. The outer housings of the Edition version in series 5 and 6 are made of titanium and ceramic.

In addition, this watch allows you to customize the straps of almost all its versions and can choose from a wide range of materials and appearance: more sporty, more classic or different colours, for example. Another advantage of the Apple Watch over other smartwatches is the GPS and the Retina screen, which has excellent colours.

Aesthetic smartwatch

If you like to follow the latest fashion, you will probably want to buy a version that allows you to change the straps. In addition, you can take into account other aesthetic criteria: that of the materials used in the design and assembly of the Apple Watch. Although most are made of aluminium, Apple also offers Edition versions with ceramic and titanium finishes, with a much more elegant and careful appearance.

What can you do with the Apple Watch?

Apple Watch allows you to make calls and send and receive messages. You can also use an application such as WhatsApp, check the weather forecast, measure your heart rate, schedule event notifications, listen to music, and use it for its primary function, i.e. to check the time. All this in just a few inches of a device attached to the wrist of your hand.

This smartwatch is also suitable for many other possible applications for practising sports without losing touch with the world. This way, you will be accessible to anyone who wants to find you without carrying your mobile phone with you. What’s new in the latest versions of the Apple Watch is possible thanks to cellular technology.

Can you use the Apple Watch for sports?

One of the main functions of the Apple Watch is to serve as a tool for those who play sports whether it’s walking, jogging, working out in the gym or even swimming.

The watch monitors your heart rate during breathing, walking, exercise, recovery throughout the day and even at night, ideal for those who have heart problems or are undergoing treatment.

Fitness apps also include calorie counting, heart rate, steps are taken, distance travelled and more.

Newer models also have GPS to help you find your location if you get lost and provide reports on distances travelled, time, average speed, and more.

Apple Watch is waterproof, and this allows you to analyze your swimming practice. Of course, to use this feature, you will need to download the required application.

What sensors does the Apple Watch have?

It comes with some sports-oriented sensors. We will explain those present in each model and their functions.

  • A barometric altimeteris an instrument used to measure altitude through changes in pressure.
  • The optical heart rate sensoruses green LEDs connected to photodiodes to analyze the amount of blood flowing through the wrist. The sensors flash hundreds of times a second to calculate the heart rate.
  • An electric heart ECG sensoris built into the back of the device to measure electrical signals that make the heartbeat. You need to place your finger on the Digital Crown and establish a chain between your heart and your hands so that you can measure your heart rate.

Is Apple Watch compatible with Android smartphones?

There is still no application that allows a secure and seamless connection between Android devices and Apple Watch. In addition, the information shared between the iPhone and the watch is encrypted, leading to greater incompatibility.

There are connection options, but you must use iPhone for the initial configuration. In addition to the fact that compatibility is not optimal, the watch’s battery runs out quickly, and the phone may present some error notifications.

On the other hand, the notification system is ineffective, as notifications look different because they do not share the same operating system. Many of them don’t even work.

Although the Apple Watch is compatible with Android, it is not recommended to connect or sync them. As the operation is not adequate and due to the incompatibility between the two operating systems and automatic encryption, there is a risk of damage to both devices.


Which model to choose?

So many questions arise when choosing an Apple Watch: What size to choose? Which model suits you? With what strap and what colour?

Apple offers many combinations, which is good for an accessory that should be practical and useful and adapted to your own taste and style!

We offer you this guide that will help you choose so that the purchase of an Apple smartwatch is completely satisfactory. Given that this smartwatch must be used with an iPhone, if you have a smartphone from another brand, you will need to look for a watch from another manufacturer.


In general, there are no big differences between some models and others. Most versions allow you to choose between two sizes. Usually, the sizes are 40 mm and 44 mm. (In older versions, there are also 38 – 42 mm). Therefore, this criterion is not so important because it does not provide much room for choice. You need to make sure it fits your wrist size well.

Which range to choose?

In addition to the size of the case, the manufacturer has thought about all users and all budgets. Thus, no less than 3 different price ranges are available. The entry-level in terms of price is the sport one, the standard model and Edition version.

It is important to mention that they all use the same operating system and electronics and therefore offer the same capabilities! They also have the same storage space. Therefore, a difference can be found only in the materials used to make the body, possibly the strap, and the glass on the screen!

Choice of strap

Apple has invented an innovative mechanism that allows you to easily separate the strap from the case. Of course, this allows you to change the strap according to your preferences. However, it should be noted that not all ranges are sold with all straps.

As for the classic model, sports bracelets (white, pink and black) are available and a classic metal strap or leather. With these models, we find the codes of traditional watches.

You can choose Nike sporty designs or sleek versions of the Edition. In this way, you can adapt the appearance of the watch to our personality and your tastes.

For the “Edtion” version, the straps correspond to a luxurious design.

There are sports models, classic or modern straps.

Choose a model according to the applications you will use most often

Are we more about calling or texting? Do you prefer to listen to music while running on the treadmill or turning on an exercise bike? Depending on which applications you use most often, this factor will be more or less important. If you want to watch videos, the models with a Retina screen will offer you a clean and high-quality image.

Desktop and watch

Smart features

With this smartwatch, you can put aside your mobile phone and use WhatsApp from its screen. With voice commands using Siri, you will perform various actions. You can also listen to music by connecting it to AirPods, paying with Apple Pay, or downloading almost any app. Of course, to make calls and have more autonomy without depending on the iPhone, you will need to use the 6 Series or SE.

Apple Watch price

In terms of price, the 6 Series is currently the most expensive, the SE is in the middle price range, and the 3 Series is the cheapest at the moment. However, it should be borne in mind that other variables such as size, features, or materials increase the final price.
