There are a lot of things to consider when you decide to buy a fitness tracker. You want to look for features that will help you monitor your heart rate and stress levels, as well as a number of other health factors. Fortunately, you can find a wide range of models on the market today, and it's easy to compare their features and decide which is best for you.

GPS

One of the easiest ways to collect and display workout performance data is to purchase a fitness tracker with a GPS chip. You'll find these types of devices have a wider array of sports to choose from, and some models even boast advanced health features.

Unlike a typical step counter, a GPS-enabled fitness tracker can measure the distance traveled, which can prove to be an invaluable tool when it comes to tracking exercise. In addition, it can help you identify your starting point and measure elevation changes.

In addition to GPS, some of the more advanced trackers can also measure blood oxygen saturation (SpO2), a feat worthy of its own mention. Even more impressive is the fact that some higher end models can also measure the ECG or even alert you to atrial fibrillation.

Heart rate monitor

Finding a heart rate monitor is a great way to gauge the effectiveness of your workouts. It also can help you keep track of your exercise, sleep and stress levels.

Heart rate monitors are also helpful for people who suffer from medical conditions such as high blood pressure. You can find a variety of models in different shapes and sizes. Some are more accurate than others.

A heart rate monitor can be paired with a fitness tracker to provide you with the metrics you need to keep track of your workouts. Using the information from your monitor, you can adjust your intensity to reach your goals and stay on track.

Sleep quality

The latest generation of wearable devices, like the Fitbit Charge 5 and Galaxy Watch 5, are a lot more than a fancy watch, they also come with a number of useful features. One of these is tracking your sleep. Sleep trackers can give you a comprehensive picture of how much sleep you are getting each night, and help you set alarms for a good night's rest.

These devices can also tell you which is the best time of day to sleep, and what you should do if you aren't getting enough shuteye. As with most tech gadgets, the sleep tracking device you buy is going to be a function of your lifestyle.

Stress

If you want to keep track of your stress levels, there are many different wearable options out there. These devices use a variety of sensors to monitor your stress levels. They are also useful tools to learn how to manage stress and improve your overall mental health.

Some devices use heart rate variability (HRV) measurements to determine stress levels. Generally speaking, high HRV is good and low HRV is bad. This measurement helps you to assess how stressed you are, and it can be used to motivate positive change.

Wearables often use sensors to track your sleep patterns and exercise habits. The Body Battery feature from Fitbit is a great example. It uses activity, sleep, and heart rate data to give you a complete picture of your stress levels throughout the day.

Accurate distance data

Whether you are an athlete or simply a fitness buff, accuracy of your distance data on a fitness tracker is important. Despite advancements in technology, the accuracy of wearable trackers is still not perfect. Several studies show that recorded distances are underestimated. However, many users trust the information that these devices provide.

A study conducted by Pobiruchin and coworkers investigated recorded distances from different GNSS-enabled devices. The results showed that the recorded distances were significantly lower than the measured ones in urban, track and field, and forest areas.

In the track and field area, the GNSS accuracy was a good 3.2% to 6.1%. But, it was underestimated in urban and forest areas.

Battery life

A fitness tracker with a battery life can go a long way in keeping you active and fit. While the battery may be the star of the show, there are many more things to consider. From the newest model to the latest hardware, a well-rounded tracker will help you track all of your activities. This includes how many steps you took, the amount of calories you burned, and how many miles you walked. In addition, the device can alert you when you have a phone call or message to answer.

The best way to ensure you get the most out of your tracker is to read up on the technology and the features and functions it can offer. Some trackers come with software that can help you troubleshoot and fix problems. You can also find one that will stream music from your smartphone.
