Fitbit Charge 3: Fitness Tracker Review

Fitbit has grown to become one of the most iconic names in the fitness tracker industry. You will most likely see people wearing Fitbits when they are running, cycling, doing crossfit, and lifting weights. In this article we will be looking at the latest from the “charge” series of Fitbit fitness trackers. Fitbit Charges have easily become the most popular series in the Fitbit brand. Today we will be taking a quick look at the Fitbit Charge 3. We are going to find out if it brings anything new to this series, and if it is really worth the asking price. This is our Fitbit Charge 3 review!


The same basic design remains unchanged since the previous versions of the Fitbit charge. It maintains is sleek, smooth appearance. The main difference, however, is in size and weight. It is overall slightly thinner and also a bit lighter than the previous Charge 2. The change in materials from stainless steel, to aluminum is what contributed to the difference in weight. The Fitbit Charge 3 now weighs 1.76 ounces. This may not be a big deal to some, but others will notice this weight difference. Now you will be happy to note that, even though the Charge 3 is thinner and lighter, it’s screen has grown in size. The display screen is now actually forty percent larger than the screen size of the Charge 2! So viewing the display is even easier than ever at this point.


The Fitbit Charge 3 now has an extended battery life. You can now go for up to a week straight on a single charge depending on usage. One of the biggest new features added to the Fitbit Charge 3 is that it is now 100% waterproof. It is fully submersible to a depth of 50 meters, so it can now track swimming as well. Next, the screen is now completely touch only. There are no longer any additional buttons anywhere on the Charge 3. Finally, they have added an SpO2 sensor. Basically what this does is measure the amount of oxygen in the blood.

The rest of the features of the Charge 3 are the features you would expect to find on most fitness trackers. You can sync it with your phone to receive text and app notifications. It has built in timers and stopwatch features. The heart rate monitor is there. It will automatically track workouts, such as running, biking, and weightlifting. If you are into meditation, it can help with guided breathing exercises as well. Finally, you can also use it to track your sleep patterns. Surprisingly, the Fitbit Charge 3 does not include a built in GPS. You can work around this easily by syncing it with your phone’s GPS though. It would have been nice had that feature been built in though.
