A Fitbit is an activity tracker that you wear on your wrist like a watch to keep track of your daily activities, including walking, running, swimming, cycling, and working out at the gym. There are two primary categories of Fitbits: trackers and watches. While Fitbit Smartwatches have functions similar to smartphones, trackers are mainly focused on measuring exercise.

Depending on the model of Fitbit you choose, some may also monitor your heart rate, sleep, and menstrual cycle to give you a more complete picture of your general health. Some Fitbits can even identify the sort of exercise you are performing (swimming, cycling, running, etc.) and provide tracking that is tailored to that activity.

Additionally, some include entertaining extras like breathing exercises, workouts on-screen, the ability to connect your music streaming service to your watch for phone-free workout listening, phone, text, and app notifications, calendar alerts, and Fitbit Pay, which may be quite useful if you forget your wallet!

Fitbit has a wide variety of models, so there is truly something for everyone in the lineup. Whether you only want to measure distance and calculate how many miles 10,000 steps equal, or want to monitor your heart rate during at-home exercises, there will be a Fitbit that’s appropriate for you.


Activity tracking: Your movements are tracked by all Fitbit trackers and watches using a 3-axis accelerometer and algorithms that search for particular movement patterns. Some gadgets also have an altimeter that can tell if you’re climbing or descending steps. Your Fitbit will calculate your steps, mileage, and calories burnt as you walk, which you can monitor on the tracker’s face or through the Fitbit app.

Heart-rate tracking: The photoplethysmography (PPG) technique utilizes light to measure the amount of blood in your wrist and calculate how many times your heart beats each minute.

Sleep tracking: Throughout the night, Fitbit uses motion detectors and heart rate sensors to monitor your habits. Your unique Sleep Score, which is presented in the Fitbit app in the morning and lets you know how well you slept, is based on the data.

Exercise tracking: You should aim to complete 150 minutes of moderate activity or 75 minutes of strenuous activity each week, according to recommendations from groups like the World Health Organization. Your Fitbit will automatically set your weekly goal at 150 Active Zone Minutes. As you exercise, Fitbit will keep track of your Fat Burn, Cardio, and Peak activity to calculate the total amount of time you spent working out. You will accrue one active zone minute for each minute spent in the fat burning zone and two active zone minutes for each minute spent in the cardio or peak zones. Your heart rate and the intensity of your exercise determine the zone you’re in.

Other metrics: Some Fitbits can measure even more health indicators and provide you a slight boost in body awareness. The only catch is that to do so, you must buy a Premium membership. Only members may access some health measures, such as heart rate variability, skin temperature monitoring, and readings of oxygen saturation (SpO2)0
