Fitbit Blaze vs Fitbit Charge 2 comparison. Both Fitbit Charge 2 and Fitbit Blaze are marketed as Active Fitness devices, offering a little bit of more features than the bare fitness band such as the Flex 2 also from the same company.

A fitness tracker and a smartwatch are two different things. They may look similar at a glance, but functionalities are not quite the same. Most fitness trackers are smaller than a smartwatch, and they don’t offer compatibility with smartphones apps.

They use proprietary apps designed by the same companies that make the device. These differences are getting more difficult to notice as technologies improve because some fitness trackers are actually compatible with third-party apps although you won’t find these apps in smartphone apps market.

Nowadays it is possible to use smartphones/smartwatch as fitness trackers with certain applications. However, many people prefer to wear purpose-built stand-alone devices to measure their fitness level, and this is where companies like Fitbit come in.

Fitbit Charge 2

The original Charge and Charge HR are best selling devices from Fitbit, so it only makes sense if the company tries to repeat the success by making a device based on the aforementioned two; Fitbit Charge 2 is the result.

It takes all favorable features from its predecessors and combines them into one package. At the same time, it also corrects many things that were generally considered wrong/lacking from its older siblings.

In terms of design, Charge 2 brings a lot of better things than previous generations of Fitbit devices. It has bigger OLED screen to display more information at a glance including notifications from smartphone.

The screen displays not only the name of person calling you on the phone, but also texts and calendar reminder alerts. Another simple yet important change in design is that fact that Charge 2 uses standard wristwatch buckle instead of a clasp. It may not seem like a big improvement, but standard buckle is more familiar and it does feel more secure on the wrist.

When it comes to functionality, Charge 2 offers a range of features necessary to keep a good record of fitness level including steps counter, calories burning calculation, sleep time, stairs-climbed tracking, and multiple exercises such as bicycling, running, hiking, and more. It covers all the basic fitness tracker functions with the addition of simple smartwatch capability.

Fitbit Charge 2 is not fully waterproof, but water resistant to prevent the device from becoming faulty after contact with water when you are in the shower, washing the dishes, excessively sweating, or just under a pouring rain.

To get accurate reading of your statistics, you must register an account on Fitbit app and provide basic personal data like age, weight, and height. Goal settings are adjustable in the app as well; Charge 2 recommends and reminds you to perform physical activity after an hour of idling.

General recommendation is to take 250 steps every hour. Thanks to PurePulse technology, the device measures your heart rate automatically and constantly. There is no need to wear chest strap, and it can even detect the kind of exercise you do.

Fitbit Blaze

Among all fitness tracking devices in Fitbit’s lineup, the Blaze is the most smartwatch-alike. It is made of two separate parts: the rectangle main unit and detachable band connected to a stainless steel frame.

The main unit has heart rate sensors on the back and three buttons on the sides to offer more traditional control in addition to touchscreen function. Fitbit Blaze looks like a smartwatch mainly because it has a square generously sized 1.25-inch screen displaying 240 x 180 pixels resolution.

Just like most fitness trackers, it does track the number of steps, floors climbed, calories burned, sleep time, and heart rate per minute. Smartphone notification covers incoming calls, texts, and calendar reminders.

Connectivity with smartphone does not end there because you can also control music player on your phone straight from the fitness tracker too. Fitbit Blaze can recognize a lot of different workouts including ones available as default options on the device and a dozen more in the app, making total of 17 different exercises including but not limited to golf, yoga, tennis, running, hiking, and more.

It does not use a built-in GPS but it pairs with a smartphone to get real time position tracking. Since the Blaze is a modular device, you can mix and match a range of different colors or materials such as leather, stainless steel, and even nylon. Standard configuration uses rubber-textured band in an assortment of colors as well.

Fitbit Charge HR vs Charge 2

Fitbit Charge HR vs Fitbit Charge 2 comparison. Charge HR and Charge 2, represent both designed for serious athletes and the more user-friendly quite well with a little bit of sophistication to cater even seasoned sport enthusiasts.

The fitness trackers scene in the market is basically divided into two major groupings: sophisticated models designed for serious athletes and the more user-friendly ones intended for the vast majority of people.

Both categories sometimes offer the same range of features with differences in analysis statistics. Athlete-focused devices can give more detailed metrics, while the less-sophisticated models provide features and data that most people can actually understand and use.

Fitbit Charge HR

One of the first things to notice about Fitbit Charge HR is that it looks a lot like Fitbit Force which now has been recalled due to thousands of reports concerning skin rashes. You can consider the Charge HR iteration of the Force without skin irritation issues but with some good improvements.

A welcomed addition is Caller ID feature, which allows the fitness tracker to vibrate and display the caller name of the person calling you on the phone. It functions like a smartwatch and Charge HR is in fact the first device from Fitbit to bring such functionality. Limitation is that there is no other alert available, neither text nor calendar reminder.

Charge HR comes in three different sizes: small (for wrist 5.5-inch to 6.5-inch), large (6.3-inch to 7.6-inch), and x-large (7.6-inch to 9.1-inch). The device is not fully waterproof, but you can safely wear it while in the shower or washing your hand. It should withstand splashes and light rain as well.

You should not wear it while swimming, however. The wristband is made of a material called elastomer; it is flexible, durable, and used widely in many sport watches. It comes with surgical-grade stainless-steel buckle. Charge HR is one solid piece, so you cannot pull out the main unit and swap the band.

Charge HR is marketed as an all-day activity tracker. It does all the usual measurements such as steps taken, calories burned, distance covered, and sleep time. More bells and whistles are available as well for examples it counts the number of stairs climbed, minute of activity/inactivity, heart rate.

Especially for heart rate measurement, Charge HR is equipped with PurePulse technology. Instead of using typical chest strap, the device has optical sensor right on the back to measure heart rate. Because you don’t have to wear any additional device, it is easy to record how fast/slow your heart beats even when you are sound asleep.

Another good thing is SmartTrack which recognizes the kind of exercise you are doing and starts the statistics measurement automatically. It prevents you from dialing up settings and fiddling with options before you start moving.

Despite the automation, Charge HR still offers manual activation of Exercise Mode. During exercise, PurePulse measures heart rate at 1-second interval and at 5-seond interval at all other times. Charge HR is powered by a Lithium-polymer battery that lasts for up to 5 days.

Fitbit Charge 2

Charge HR is the predecessor of Charge 2; the latter does everything that the former can, added with even more features and improved design. Basic models of the Charge 2 come in small, large, and XL, but there are other options including stainless steel frame and Special Edition with gunmetal band.

Fitbit Charge 2 is a modular activity tracker, which means you can pop out the sensor/main unit and pair it with another band of your own choosing. It also has larger OLED screen because it needs to display more complex information too. You have the option to choose from several clock faces.

Apart from the regular all-day activity tracker functionalities, Charge 2 is compatible with more smartphone notifications such as texts, calls, and calendar alerts. You can also connect it to your phone to activate GPS tracking feature.

To satisfy more serious users, Charge 2 now has Cardio Fitness Level mode to analyze overall fitness score based on estimation of VO2 Max (the maximum amount of oxygen human body can consume during the most intense exercise).

It is safe to say that Charge 2 is trying to get into a different market segment by providing more detailed overview of fitness condition in addition to regular activity tracking.

Charge 2 also does Multi-Sport Modes to analyze statistics on specific exercises like weight lifting or running and Guided Breathing Sessions to help you relax by offering personalized inhale/exhale training based on real time heart rate.

A device marketed as a smartwatch can also count the number of steps you take, and a device marketed as fitness tracker can receive phone notifications as well. Take two Fitbit devices for example: the Fitbit Alta and Charge 2.

Fitbit has always been associated with fitness activity trackers, but the aforementioned examples can cover basic smartwatch functions, too. Both are capable devices as activity tracker equipped with notification features to display text and phone calls right on your wrist.

Fitbit Alta

Just like most of its competitors, Fitbit offers a range of products categorized under different families including Everyday Fitness, Active Fitness, and Performance Fitness. Fitbit Alta falls under the first category. It does all the usual functions you expect to get from an activity tracker including:

  • All day activity: Fitbit Alta tracks number of steps taken, distance covered, and calories burned.
  • Inactivity data: it tracks both active and inactive minutes.
  • Reminder: there is a reminder function to motivate you to move after a period of inactivity.
  • SmartTrack feature: automatic recognition and recording of exercises.

One thing that makes Fitbit Alta stands out from the crowd is actually the way it looks. Compared to previous generations of activity trackers from the same company, the Alta retains a lot of design cues but with some improvements.

It is still a modular device, which means you can swap out the main unit (sensor) and put it in a different yet compatible wristband. Fitbit Zip and Fitbit One also have the same design, but the Alta is better in terms of usability.

Fitbit Alta is not a device that you clip to a pair of trousers, but you wear it on your wrist just like a watch. Since it also displays notifications and calendar alerts from smartphones, you get everything right on your wrist.

Fitbit Alta uses the same companion app as all other Fitbit activity trackers currently use. For long-time Fitbit wearers, nothing in the app has changed; for newcomers, the app should not be difficult to navigate either.

Once downloaded and activated, you can sync the app with Alta and you are set. Although you don’t actually need to browse through a lot of settings, the app offers that option if needs be. It is easy to adjust little details such as daily workout goals and water intake.

Sleep Schedule is a newly added feature that allows you to take a good look at your own sleeping pattern and compare it to other users’. You can use this information to improve the pattern, get better routine sleeping/waking-up schedule, and generally improve health.

Despite all the simplicity, Fitbit Alta is designed to cater both veteran and first-timer. Simple interface and straightforward functions make the device enjoyable and usable at the same time.

Fitbit Charge 2

Sitting directly ahead of the Alta in Fitbit’s product lineup is the Charge 2. If you are familiar with Fitbit, you can immediately notice that Charge 2 is the successor or at least intended as an improvement over the original Charge.

However, there is only one noticeable improvement: the screen size; not much has changed functionality-wise. Fitbit is a company that makes easy-to-use activity trackers device, not a complicated full-blown athlete-focused sport computers.

Equipped with common features including heart rate tracking, sleep monitoring, calorie computation, and steps counter, Charge 2 deserves a respectable space in the market due to its completeness and affordability.

On the software part, there are two notable improvements including PurePulse and multi-sport tracking. PurePulse is a heart-rate monitoring technology powered by wrist-based sensor, so there is no need to wear a chest strap. In other words, it is a continuous heart rate monitoring even when you are asleep.

Its multi-sport tracking deserves a mention, too. It covers a multitude of exercises such as walking, running, weight lifting, cycling, interval workouts, and indoor running on treadmill.

Fitbit Charge 2 detects every activity automatically that you don’t have to press a button to start a session. For example, if you start running on treadmill, it detects your movement and starts monitoring right away.

There is also an option for manual pause for better data accuracy. Additional features include music control, guided breathing, and floors climbing tracker.
