The 7 Best Fitness Trackers Smartwatches for Everyone

The best fitness trackers or smart bracelets will encourage you to exercise, you will know what days and hours your body responds best to practice sports and when you should rest. You will also have all your records to go setting and exceeding new goals.

Unlike sports watches, fitness trackers are smaller, more comfortable, and discreet, they do not attract attention and how you can sleep with them you will know how you have been rested. They would be for people who play sports frequently or for those who need a boost to get active.

On the contrary, sports watches sacrifice comfort to gain performance and reliability of measurements. They would be for professional or amateur athletes who compete and who perform systematic and thorough training. But do not worry, the bracelets that I bring you to this article have little to envy many sports watches.

The smart bands record your physical activity diary (steps, distance, promoted plants, calories burned …), your fitness (average and maximum oxygen level in the blood), and can even detect and prevent health problems (heart rate and sleep quality).

There are many models, each one specialized in an activity or sport and with some or other functions that make them more appropriate for women, children, runners, cyclists.

Anyway, there is a lot to choose from and it is advisable to find out so as not to spend good money in a bracelet that you do not use even half of its benefits, or worse, that ends up forgotten in a drawer. So that this does not happen to you, here you will find an analysis of the best models, their pros and cons, a comparison, and a buying guide.

It has a sensor to measure blood oxygen saturation (SPO2) and the maximum volume of oxygen that your body can process (VO2 max). Very useful to know your state of form, for people with allergies or respiratory problems, as well as to detect sleep apnea.

The Charge 3 bracelet has practically the same features and functions as the 4. The biggest difference is the absence of integrated GPS and therefore less precision in the calculation of distances and you will not have the route of your walks or training. This can be solved by connecting the GPS of the mobile with the bracelet. It does not prepare the training intensity map, nor does it quantify the minutes in the active zone, nor does it allow controlling the music on the mobile.

3. Garmin Vivosport

The Vivosport smart band is very comfortable, ergonomic, slim, and discreet. Available in various colors and in 2 sizes. It has an integrated GPS to practice sports outside without having to carry your mobile and be able to accurately measure the distance, know the route, and know the accumulated unevenness with the help of the altimeter. The battery with the GPS lasts 8 hours and 7 days without use.

A very good option for strength and high-intensity exercises and for running on a treadmill thanks to an accurate accelerometer. The training function records the different types of exercises, the number of sets and repetitions of each of them, and the rest periods. If you are one of those who rear up practicing Crossfit, HIIT, or weights, you are going to get a good performance.

With all the information it collects, it will set calorie goals, steps, times, and distances. You will know which day to rest and which day to exercise at the times that are best for your body. In short, it is a very powerful smart device to know your state of form and how you are progressing, while alerting you to any respiratory disease or sleep problems.

The Garmin Connect App is the most complete but less simple than the Fitbit App. It produces all kinds of reports, graphs, and statistics, so if you are very analytical, constant in your training, and want to train at the highest level, here you will have a place to entertain yourself.

You can also share your workouts, achievements and meet people. You can connect it with Strava or MyFitnessPal. The OLED color and touch screen measure 0.8 inches are easy to manipulate, and always stay on. Good resolution and adjustable brightness for outdoor viewing.

4. Garmin Vivosmart 4

It is a stylish, light, sporty, and elegant smart band. Available in various colors and would be for people with a demanding lifestyle. The Vivosmart 4 smart bracelet differs from the Vivosport in that it does not have an integrated GPS, although it does have a very precise accelerometer and barometric altimeter to partially compensate for the absence.

Something that few activity bracelets have is an energy meter in your body (Body Battery) that will help you know when it is convenient for you to rest or exercise. And if you are especially concerned about your health or suffer from respiratory disease, it has a pulse oximeter to accurately measure the level of oxygen in the blood (SPO2) and the aerobic capacity (VO2 max.)

Another difference with the Vivosport is that the screen is monochrome, smaller, it adapts its brightness automatically to the levels of exterior light and only activates when you need it. It is perhaps a bit small and lacks some resolution, so if you have a vision problem you will have to bring it closer to read the data. Also when it gets wet it is not easy to handle.

Finally, if you are a swimmer, it could be a good option as it has a programmed swimming function with which you will see the number of lengths on the screen, and once other records are synchronized with the mobile, but not the heart rate.

The Fitbit Charge 2 quantifying bracelet is the one that wears the most in the market in our ranking, but it continues to sell very well and that says a lot about its quality. It has an elegant and sophisticated design both for day-to-day and for parties and events. It is available in various colors and in 2 sizes.

It is somewhat heavier and thicker than the Charge 3. The screen is smaller, with less resolution, and less resistant since it is not Gorilla Glass. It is not submersible so you will not be able to bathe with it, it is only waterproof against splashes, sweat …

The battery life is 5 days compared to 7 for Charge 3, it does not measure oxygen saturation in the blood and it does not have Fitbit Pay to make payments. It does not allow you to respond to SMS, call or calendar notifications, which are the only ones you receive. Therefore you will not receive notifications from WhatsApp, mail, or social networks.

The analysis of the quality of sleep presents a problem with respect to Charge 3, it does not allow to deactivate the active screen function and it lights up every time you move in bed. All other functions and features are the same as the Fitbit Charge 3.
