How do I choose a smartwatch In 2021?

Buying a smartwatch is always an excellent decision, although, without the right information, you may feel somewhat overwhelmed. Here we discuss the most important aspects for you.

  • Compatibility

Smartwatches are usually used in sync with a smartphone. That’s why it’s important which compatibility the smartwatch you choose can support. This way, you can get the most out of both your smartphone and your smartwatch.

On the other hand, you also can use a smartwatch, without the need to sync with a smartphone. As we have mentioned, however, you will not be able to take advantage of all the capabilities that each electronic device has to offer. The main compatibilities are focused on Android, iOS, and iPhone operating systems.

Therefore, it is highly recommended that you choose your next smartwatch model according to the model of smartphone you already own. After that, you will be able to enjoy a much more complete and extensive operation.

  • Comfort

One of the most important aspects of a watch in general is the comfort of use. Most smartwatches are an excellent complement to be used for physical activities. Therefore, the unit you choose should provide comfortable wear at any time.

Therefore, a minimum level of discomfort in the design of a watch would be a major obstacle. This is especially true when people decide to run, cycle, or swim. Therefore, it is recommended here that bands are made of a comfortable and soft material.

In turn, if you do not intend to use your smartwatch for physical activity, this aspect may not be so important. Also, you can choose a model that allows you to have an excellent tool, without causing major problems.

  • Media

In particular, this feature is important as it will indicate the ability of the watch to play music. Whether you are doing a physical activity or not, having a music player in your watch is an excellent complement.

At the same time, some models can be complemented with a wireless headset to optimize every experience. However, not all models available today can offer you this particular feature.

Also, each music player may require a subscription from you. Beyond that, it’s one of the best complementary features a smartwatch can provide, among many others.

Therefore, we recommend that you purchase excellent music playback capabilities. In this regard, some models of smartwatches include storage memory to better increase this capacity.

  • Message Responses

In particular, the message response capability of a smartwatch is one of the main functions. When you use the voice dictation of your smartwatch, you can send and receive commands to your smartphone.

This is highly convenient and avoids the need to check your smartphone. Use this option to activate the music player, among other useful functions. However, you should be aware that not all units available today can provide this capability.

On top of that, you will also have the ability to reply to messages you receive from your contacts. So, this saves you a great deal of time, since you won’t have to use your smartphone to do so. Greater convenience is never an afterthought, right?

  • Apps

These days, the vast majority of smartwatches support a large number of applications. Each of them can provide you with a certain utility or entertainment. In particular, proper compatibility with a smartphone’s operating system is necessary.

So, you can count on certain applications like Spotify or Amazon music. At the same time, certain applications can be useful for your physical activities. One of them is Google Fit, although others are very useful.

On the other hand, you can use applications that are intended to track and monitor your health. In this sense, you will have the ability to measure the distance you have traveled, the calories burned, the stages of sleep, among other features.

  • Notifications and Alerts

One of the aspects that provides the highest level of convenience is receiving alerts and notifications. This will give you a greater level of freedom in receiving any type of notification. Besides, this quality is optimized when you have your smartphone and smartwatch properly synchronized.

For one thing, you will have the ability to receive alerts and notifications for calls, messages, e-mails, and the like. This way, you will not have to check your smartphone every time. This is even an excellent feature when you are doing physical activity.

Also, you will be able to receive certain alerts for health factors. Some models can be configured to produce alerts if your heart rate is too low or too high. Therefore, you can monitor your heart rate during physical activity, or if you have heart disease.

  • Battery life And Charging

For the vast majority of mobile devices, battery life is an important aspect. In this case, this quality can indicate whether or not you should charge your smartwatch once a day. This is why most of the models we have analyzed provide an excellent time of use.

At the same time, it is necessary to note that this usage time may decrease with frequent use. Therefore, this means that the battery life may be depleted. In this way, the usage time of each battery life cycle also decreases.

It is therefore advisable to have a smartwatch that provides a long usage time. Besides, the time needed to fully recharge the battery is also an important factor. In other words, a smartwatch that takes too many hours to recharge the battery is not very useful.

  • Water Resistance

Today most smartwatch models are waterproof. However, this resistance is not always the same in all cases. Some units can only withstand splash water. Also, the more advanced models are submersible up to 50 meters or more.

Therefore, you should consider whether you usually want to swim. This way, when you are immersed in water, the operation of this electronic device will remain intact. Also, this is often very useful for continuing to measure your heart rate, among other statistics.

On the other hand, if the smartwatch you have chosen is not submersible, then it would be a bad idea to enter a pool with your watch on. At the same time, completely waterproof models are usually much more durable as well.

This means that they will be able to withstand more intensive use. In particular, this can be an advantage for any kind of physical activity.

  • Heart Rate and GPS (Fitness Features)

There is a large number of users who do some kind of sport or physical activity of different intensity. For all of them, both GPS and heart rate monitoring are the main functions they will use in a smartwatch.

In general, the models we have analyzed can provide each of these features. On the one hand, the GPS function will provide you with the right guidance when running or cycling. In this case, you should keep in mind that the battery usage time of any model decreases dramatically.

On the other hand, heart rate monitoring can be combined with other complementary statistics. Some useful statistics are step count, speed, distance traveled, and several calories burned. This makes it an excellent fitness tool.
