Fitbit has improved the materials used in its straps dramatically over the past five years. The original Charge launched with a strap that irritated a lot of people's skin, but this new version was comfortable throughout our review period.It felt comfortable, and compared to many other fitness trackers this is a lot easier to wear throughout the day.

The Fitbit app, which was recently redesigned, has a user-friendly interface. At the top of your dashboard you’ll see your steps for the day, with arrows on either side to jump a day before or forward again; below that are snapshots of floors climbed, miles traveled, calories burned, and minutes of exercise.

The main change with the Fitbit Charge 2 is its more sizeable display – it’s four times larger, in fact. This means significantly more at-a-glance information and better handling of notifications from your connected smartphone.

Overall this model was very easy to use, very accurate for counting steps, and very good at measuring heart rate accuracy.
- Consumer Reports
The Charge 2's new selection of watch faces and the larger vertical LED display mean I can see time, steps and heart rate all at once.

It has bigger screen means you can see more stats at a glance.

The Charge 2's heart rate monitor proved more accurate. In addition to resting heart rate, the Charge 2 can also estimate your VO2 Max score, which it dubs "Cardio Fitness."

It is easy to use and syncs automatically with many different devices.

Fitbit Charge 2 personalises its guided breathing exercise by taking your heart rate to find a good rhythm, making sure you're not inhaling too deeply or exhaling too quickly. This is actually the debut of some serious new tech for Fitbit, and is the first time heart rate variability has been used on its devices.

Charge 2 finds a more natural place in Fitbit’s new-look lineup – not least because it’s the cheapest model to offer 24/7 heart rate monitoring.

What experts didn't like

Can't be submerged or worn in the shower

You won't be able to wear the Charge 2 in the shower or when swimming, though

Fitbit added a big display and multiple-sport modes to the wristband… but didn’t add a pause function. No button, no tap-to-pause option, nothing. So if you need to stop during a workout — to tie your shoe, wait for a friend, or catch your breath — you can’t. It’s also not waterproof.

Annoyingly, maybe one in four times the display failed to turn on automatically. There is a button on the side to manually turn it on and toggle through the different displays, but for times when your other hand is occupied, the finicky display is a frustration.

Requires included proprietary charging cable which can be expensive and time consuming to replace

Not water-resistant for swims or showers.

Unwieldy guided breathing implementation.
- Engadget
I do wish the Charge 2 were waterproof, or at least water-resistant, like the vivosmart HR. While you can splash a little bit of water on it, taking it swimming is a no-no.

Heart rate sensor doesn't always work properly.
- Runner Click
It is a little annoying that you can't scroll back, and instead must keep tapping to get back round to a previous screen that you might have missed. There aren't a lot of screens to go through but it's still a hassle if you're in a rush.

An Overview On Fitbits

Knowledge is power, and fitness trackers provide a wealth of health knowledge right at your fingertips — or, more accurately on your wrist. With the right fitness tracker, you can power up a healthy lifestyle and a new you.

As a result, wearable technology, like fitness trackers and smartwatches, are valuable tools to help you achieve your goals. These devices do so much more than tell time or add a pretty accessory on your wrist. They record and monitor movement and fitness-related activities. They track the number of steps taken, distance walked, sleep duration and quality, heart rate and more. Some advanced models have separate modes that enable them to track specific types of exercise and can distinguish between swimming, running and cycling and keep logs of your favorite routes. Then, you can connect and upload all the stored data to your computer or smartphone to analyze and learn from your activities.

It’s not a passing trend either. In fact, the global fitness trackers market clocked in at just under $18 billion in 2016. That value is expected to grow to more than $62 billion within the next four years. Smartwatches, specifically, are driving most of the predicted growth. Some of the leading fitness tracker manufacturers include Fitbit, Samsung, Nike, Adidas, Google and Apple.

Fitbit is one of the most popular fitness tracker manufacturers. The company launched its very first tracker back in 2007. Since then, it has introduced innovative new technology and features. Now, Fitbit offers a wide variety of different fitness trackers and smartwatch models at a relatively affordable price range. There are high-tech models with detailed data tracking for serious athletes, as well as simple watches, like the Fitbit Flex 2, for those dipping their toe into fitness tracking and data. There are also Fitbits made just for children ages eight and up to encourage movement and healthy habits early. Whether you’re trying to make fitness fun for youngsters or start your own health challenge,  there is a Fitbit for everyone and every goal.

All Fitbits are designed to seamlessly track every part of your day — including activity, exercise, food, weight and sleep. As a result, the company says they will “help you find your fit, stay motivated and see how small steps make a big impact.”

They monitor heart rate with PurePulse. The newest watches, like Fitbit Charge 3, Fitbit Versa 2 and Fitbit Ionic, include SmartTrack. This innovative technology automatically senses different types of exercises and records them accordingly in the Fitbit app. For example, if you hop on a spin bike and start pedaling, the watch will begin recording as a cycling activity.

The current Fitbit smartwatches, like Fitbit Versa 2 and Fitbit Ionic, also incorporate apps and features like wallet-free payments, calendar alerts and text message updates. Today’s Fitbits and fitness trackers are so much more than step counters. They also enhance and ease many everyday tasks.

In addition to encouraging healthy lifestyles, Fitbit connects all users in a like-minded community. Here, you can share your goals and find motivation from people around the world. It also offers fun competitions with friends, family or coworkers on a variety of statistics to push yourself farther.

All those Fitbit insights add up to real lifestyle changes. In fact, researchers from Arizona State University discovered that the combination of wearing a Fitbit Zip activity monitor and expressing more mindfulness throughout the week increased levels of physical activity. For a relatively low cost (most models range from $50 to $250), fitness trackers help motivate you to kick-start and stick with a fitness plan, hold you accountable, encourage goal setting and, best of all, can help you lose weight.

Pick the right Fitbit fitness tracker, and you’re well on your way to living your healthiest life and achieving your goals.
