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.
