Fitbit Charge 2 Wearable Fitness Trackers with Heart Rate Review

Written by

If you unfamiliar with Fitbit or you’ve never owned a product from Fitbit, the Fitbit Charge 2 is the new redesigned to replaces the original best-selling fitness trackers Fitbit Charge and Charge HR. With interchangeable straps, new sports features, a larger display, and updated fitness features. The all-new Fitbit Charge 2 fitness trackers with heart rate monitor wristband built for all-day, workouts and beyond.

You can track specific exercises, such as running, weights or yoga, to see their workout stats on the tracker’s display. Track heart rate continuous, better track calorie burn and get a clearer picture of your fitness level. The larger interactive OLED display helps you stay connected with call, text and calendar alerts. With more advanced features in a sleeker package, it’s the motivation you need to push yourself further every step.

Fitbit Charge 2 continues to track steps, distance traveled, calories burned, active minutes and hourly activity, plus sleep duration and quality by using its MEMS 3-axis accelerometer. It also has an altimeter that records the number of floors climbed.

The PurePulse continuous heart rate monitor allows you to monitor workout intensity and calories burned, plus see the results via interactive charts and graphs on the app and dashboard. The heart rate icon on the display can tell you what you’re in one of three heart rate zones: Fat Burn, Cardio, and Peak.

The heart rate monitoring worked very well with the new interval training feature, which guided us through alternating periods of high-intensity exercise and recovery to maximize workouts, so you can stay focused. However, it uses an optical monitor that detects the pulse by shining a light through the skin to see your blood flow. So it isn’t 100 percent accurate but will give you an indication of your heart rate, which will be fine for the most casual sportsman.



Fitbit Charge 2 comes with adding Reminders to Move, which prompts you if you aren’t moving enough, at least 250 steps per hour during the day. The Charge 2 also expands on the HR’s tracking capabilities, with a connection to your smartphone’s GPS for data on pace and distance.

Another new feature in Fitbit Charge 2 is the Fitbit Cardio Fitness Level, which allows you to see a snapshot of your fitness level. You’ll get a rating based on your resting heart rate and personal information from your profile, which compares your fitness levels against other people of the same age range and gender.

Fitbit has also introduced Guided Breathing, which is designed to slow your breathing rate to calm you down and help you feel more relaxed throughout the day with personalized breathing sessions based on your heart rate. It uses the built-in vibration motor so you can breathe in sync without looking at the screen.

Fitbit claims that the Charge 2 has a battery life of up to five days, slight reduction from five+ days from the older Charge HR, probably due to the larger display. The charger is a new clip style and fits nice over the sides of the tracker, another good improvement. The Charge 2 stand for water resistant only. So is fine against sweat, rain, and splashes but not for a dive in the sea or swimming pool.

The mobile app is excellently designed, with simple, clear graphics that show you how you are doing to finish those daily health metrics such as step count, distance, floors climbed, calories burned, and much more. Each data can be detailed for historical analysis, so you can see how all that exercise is helping you get fitter.

Larger Display
The most obvious improvement is the larger interactive OLED display, which shows more fitness data right on your wrist. The bigger size screen can help you to push the device’s button less and add more readability. You can personalize what you want to see, and choose from different clock styles via the app. You can wear the Charge 2 as your main watch and this tracker will certainly offer you more than a traditional wristwatch with the call, text and calendar notifications plus the fitness tracking features.

Interchangeable Straps
Straps are another part to be improved in this model. You couldn’t replace the wristband in the older Charge HR, so if it was damaged you had to buy a whole new, of course, this is the most complaints in the past. Now, Fitbit has fixed this by giving the Charge 2 interchangeable straps, so you can swap around colors, personalize your style for any occasion and worry-free when it damage. The Charge 2 use the same stainless steel watch buckle as in the HR model, which is much more secure than the pop-in clasp connectors of the Alta.

The Fun Part
The Fitbit app added a seriously impressive fitness game, making fitness fun and competitive. It’s a real motivation to take part in step count against friends, colleagues, and family. Fitbit Adventures is a new series of immersive Challenges in the app (it’s in the challenges section) that let you virtually exploring scenic destinations and even compete on famous running courses where your step count is shown on an actual map. Get more steps by seeing how you are doing on the New York City Marathon or Yosemite Vernal falls. With each of your real-world steps, you virtually advance on a preset route. When you come across markers, and reach them, it will show you where you are with the beautiful panoramic pictures. You also find random “gems” on the map which can collect to earn a badge.

The Fitbit Charge 2 is a worthy upgrade because of its great build quality and the big improvement from the Charge. You will love the larger display and interchangeable wristbands, plus the updated fitness features like better heart-rate and exercise tracking. It has most of the features a serious keep-fit enthusiast demands plus the best fitness app that is included at no extra charge, while priced extremely fairly for all that it offers. What a nice wearable fitness trackers!
