The best smart watches and physical activity wristbands (smart watches, October 2017)

December 05, 2017


The world of wearable devices or wearable devices (in English wearable devices or wearable) does not stop being for now a minority sector. But month by month the number of units sold increases and with them the interest of the rest of the consumers, although focused on the activity bracelets. In addition, after the arrival of the Apple watch, the rest of the smart watches have been selling better due to greater consumer attention in alternatives with Android.
The most interesting products right now are smart watches (in English smart watches) with Android Wear, Google's bet for the sector and compatible with both Android and iOS phones. But there are also other systems like the one used in Pebble watches, the Microsoft Band bracelet, or watches like the Samsung Gear S3 that use Tizen.

The most common use currently given to wearable devices is to quantify physical activity, such as keeping track of steps, calories burned, or sleep cycles.

Xiaomi has the cheapest physical activity bracelet on the market, but that does not mean it is not useful. It will keep track of the steps taken, calories burned, distance traveled running and running, and sleep phases. It also vibrates to notify you of calls, wake up and you can unlock your phone with it.

Although it does not carry GPS, it does include a heart rate reader. For less than 20 euros, with a good Android application to set activity objectives, it is a great investment.

Garmin vívosmart HR +

Garmin has a popular vívosmart HR, which the company has slightly renewed calling vívosmart HR +, and gaining GPS in the process. It has the same heart rate sensor, accelerometer, water resistance up to 5 ATM and ability to track activities such as walking, running, cycling or swimming.

It provides information about sleep patterns, exercises performed and comparisons of distances traveled thanks to your GPS. It lasts up to five days of use with the active heart sensor, or up to eight hours in a row of GPS usage.

Withings Activité

This watch could easily be confused with a normal one because Withings has put its attention first on the design and then on its features. Includes leather strap, water resistant, sapphire crystal that holds up to 5 ATM, made of stainless steel in Le Locle in Switzerland.

The different sensors included allow you to count steps, distance traveled, sleep cycles, heart rate monitor, and also serve in April for swim distance. It uses a button cell like any other clock, and its autonomy reaches 8 months.

Polar M200

The M200 includes both GPS and a heart rate sensor. This bracelet allows you to keep track of various physical activities, such as steps taken, distances traveled, calories burned, and make notifications of inactivity and others, but does not allow receiving notifications from a phone.

After the addition of the heart rate reader, it also keeps track of the sleep and its quality. The strap is made of plastic, but can be exchanged for others that Polar sells.
Fitbit Charge HR

This bracelet includes a heart rate detector that works continuously, and is ideal to have exact measurements of the calories you burn, the steps you take, the sleep cycles or distances traveled. It has autonomy around five days.

Casio WSD-F10

The traditional watch makers almost got into the world of smart watches with the WSD-F10. It is a model designed to practice outdoor sports - hence also its robust appearance - and includes direction, altitude, atmospheric pressure, indication of sunrise and sunset, tides and calories. Pretty complete.

For this, he has chosen to use Android Wear, and develop specific applications for different activities, such as hiking, cycling or fishing. The watch includes some additional watch spheres that include some complications - watchmaker language for information that is not the time -, such as altitude or atmospheric pressure data.

In addition to the Google Android Wear application, certain parameters can be configured from the Casio Moment Setter + application, and the watch will notify when the ideal time to practice the favorite sports of the carrier.

Fitbit Surge

Fitbit Surge is an interesting connected clock. It has 3G connectivity and GPS tracking, so it will be very useful for many of those who go out to run. It is accompanied by a good number of sensors, including heart rate, to keep a good record of our physical activity, sleep cycles and food database.

The biggest drawback that Fitbit Surge has is its design, since being a product of 300 euros you could have expected something much better in this regard. It is something thicker than many users would like, but it has a lot of functionalities that manage to counteract this aspect.

Garmin Vivofit
A good and basic bracelet, able to measure distances, sleeps cycles and resistance to water. The main drawbacks is that the screen does not have backlighting, nor does it include an altimeter or smart alarm, so it has limited features, but it has autonomy for a year and you do not need to take it off before going to the shower.


Focused on notifications and physical activity

Both smart watches and fitness wristbands are focused on including various sensors to measure the steps taken, distances traveled or monitor sleep and heart rate. At the moment there is no definitive application that justifies the purchase of a smart watch outside of these more physical uses. Also the sensors, especially the heart rate, has a sufficient accuracy but not ideal for other purposes such as conducting a medical evaluation.

That's why clocks are designed to access important information for a few seconds, such as notifications or fast sending of a text message, but nothing that requires more than 10 to 15 seconds. Due to its low battery, in the range of 300 to 400 mAh in the case of watches with color screen, to use them intensely none would last more than 2 or 3 hours. Any task that can’t be completed in a few seconds is best done with the phone.

The battery life of Android Wear increased with one of the first updates, from just a day of average use to two days, and some users get three days out if they do not use it too much. Almost all the consumption in this last scenario refers to using it for notifications, but not for GPS or 3G. In this type of watches (and also the activity bracelets) with GPS do not wait more than a few hours of duration when active.

In the field of connectivity, due to its small size and need to consume little, its antennas are not especially good. They comply, but they will have more coverage problems than you would have with your mobile. They can’t radiate to as much power as a phone or they would run out of battery in a tiny space of time.

Currently, GPS and GLONASS are also used simultaneously in phones to avoid certain moments of loss of coverage that exists using only GPS and also improve their accuracy. Since the watches that include positioning system only use GPS as a general rule, and using low power chips, they are not the most reliable and will not replace the need to use the phone if you drive to get reliable addresses. They are enough to navigate, more or less, around the city and record the approximate course we have taken when going for a run, walk or pedal.


The options of watches with Android Wear are also the most interesting since the developer community is more extensive and will have support for an indefinite period.
