Fitbit Flex 2 Review

Fitbit Flex 2 Review

The Fitbit Flex 2 is a major upgrade to the original one. It’s even better than its predecessor in almost every way. And definitely worth the upgrade if you’re looking for a fitness tracker. However, there are some merits and demerits that you need to consider while going for it!

Flexible Wearability of FitBit Flex 2 – Pretty Good!

Most of the users being skinny are often concerned about the flexible wearability of a fitness tracking band. But with FitBit Flex 2, this is not a problem anymore! That is because it doesn’t have an obnoxiously large band and is more comfortable than the original Flex.

In addition to that, this device can be worn on either hand or on either wrist, which makes it easier for people who are left-handed or right-handed to use it. So, the Fitbit Flex 2 bands are an excellent choice for someone who wants to get into wearable tech without spending too much money.

Fitness Tracking Functions – Decent?

Fitness Tracking Functions

As we know that the Fitbit Flex 2 is a wearable fitness tracker with a wrist-based sleep tracking function, which is why its tracking functions are a matter of concern. But you don’t have to worry!

It has the ability to track one’s sleeping quality, the number of steps taken in a day, and calories burned, along with a fitness-tracking app that offers the features of challenges, workouts, food tracking, and more! What else do you need?

But there’s more; the Fitbit Flex 2 can also be used to keep track of how well you are doing towards your set fitness goals. Because it offers comprehensive statistics on daily activities and it also has a silent alarm that will gently vibrate to wake you up in the morning without disturbing your partner or anyone else who is sleeping nearby.

Sleep Monitoring Feature – A Plus Point? 

The sleep monitoring feature in the FitBit flex 2 has really been a revolutionary change for those who have been struggling with problems of quality and quantity of sleep because it acts as a wearable device that detects your movements and records your sleep duration and quality.

Other than that, it has helped people realize the things they were doing wrong, like drinking coffee before bedtime or not exercising enough during the day. This way, people can take steps to improve their sleeping habits and start sleeping better.

Moreover, this sleep monitoring feature is exclusive to the Fitbit Flex 2 and requires a Bluetooth connection to your phone. When enabled, this provides real-time feedback on how long you were in light, deep, and REM stages of sleep.

It also tracks how many hours you slept and when you woke up during the night. And the wearable features an alarm clock too that can be set to go off at a certain time or after a certain duration (e.g., 5 hours). So, it’s surely a plus point!

Is the App User-friendly?

Because of its straightforward layout and easy-to-navigate platform, the Fitbit application is one of our absolute favorites in the activity-tracking area.

The app appearance is the same regardless of the Fitbit tracker. However, functions vary based on what your device is able to track. At the bottom of the application, there are four tabs on all devices: Dashboard, Challenges, Friends, and Account (along with a “+” for fast access to monitoring an exercise or recording weight and food).

The Dashboard page provides a day-by-day breakdown, covering everything from the number of steps taken, as well as calories burnt to sleep length and active minutes. There are tiles for statistics like water intake, food intake, and weekly exercise, which may be adjusted to display in the order you like by pressing “Edit” at the bottom of the panels.

As with the Charge 2, some functions could be easier to find, such as activities recognized by SmartTrack (which are concealed within the weekly workout tile). However, most of the settings and capabilities are accessible at first glance.

In the top left-hand corner of the user interface, there is a tiny graphic of the Flex 2. Plus, a battery indicator. Clicking on this takes you to the tracker’s settings, which include the hand you’re wearing it on, major goal preferences, and phone notification settings. You can also personalize reminders to relocate here.

The Tasks page contains a variety of challenges to help you move, as well as an Adventures feature that debuted with the Flex 2 and Charge 2 models (which is also available on the other Fitbit devices). This feature allows you to go to new places by working toward a different step target each day based on your seven-day average.

The Account tab is last but not least. You can adjust your account, modify your goals, connect third-party applications like MyFitnessPal, and change things like stride length to improve accuracy.

Is the Size of the FitBit Flex 2 is Great for Ceilings & Wristbands?

Size of the FitBit Flex 2

Now that is a matter of concern for those who have extra fat and want to wear it on their ceilings and wristbands. But, there’s nothing to worry about as the size of the FitBit Flex 2 is perfect for those who want to wear the device on their wrist and others who want to wear it on their ceiling.

The device is small and light and can be worn as a watch or clipped onto clothing for those having extra fat and muscles. Wearing a fitness tracker as a bracelet can be attractive, but it can also have drawbacks.

As it may not have enough space to fit other bracelets or large jewelry, which might keep you from wearing your favourite pieces. To avoid this problem, you should find one that’s big enough to fit your personal style without being too big for your wrist!

Is it Waterproof? – A Merit?

The Fitbit Flex 2 has a water-resistant design which means it can withstand sweat, rain, and occasional spills. But it is not designed to be used in the shower or to track your swimming laps. So yes, it is waterproof!

FitBit Flex 2 Design – Good or Bad?

FitBit Flex 2 Design

There’s no doubt that Fitbit Flex 2 is a good addition to the fitness tracker market and is highly recommended for those looking for a reliable and sleek device. It is a slim, small, and discrete device that doesn’t look bulky or out of place on one’s wrist.

But, it does not have an on-screen display which can be seen as either a positive or negative characteristic depending on how you look at it. On the one hand, the absence of a screen means that it will less likely run out of battery life as quickly as other models.

On the other hand, the lack of a screen means that there are no stats available to show real-time information about your activities. But there’s a plus point that it comes with interchangeable straps which allow you to change up your look and style every day.

However, the unavailability of the screen is not a big crash, but it still depends on your taste. As it gives a sleek and different look without a screen, it can be counted as merit instead.

It’s Battery Life – Definitely a Demerit!

FitBit Flex 2, without a doubt, is a better version of the FitBit Family. But its battery life could have been much better, considering its price range, because it has a battery life of only 3 to 4 days which is very low. It could have not been counted as a demerit, but it has one more flaw!

It doesn’t give any warning or vibration on low power or while turning itself off, which is very frustrating. Because you can miss and lose track of your fitness record, the steps you’ve taken, the calories you’ve burnt, and much more. So, it’s definitely a demerit!

Comprehensive List of Pros & Cons:

Although FitBit Flex 2 is a star among fitness tracking bands in the market, it also has some pros and cons that you need to consider!


  • It is water-resistant
  • It is flexible
  • It has a sleep monitoring feature
  • It is an all in one fitness tracking band
  • It is lightweight
  • It is portable
  • Price is comparatively average


  • Battery life is not great
  • Not good for tracking swim records
  • No screen display

Warranty information

The guarantee will cover product problems for two years from the date of purchase – otherwise, if you are unhappy with your new Fitbit Flex 2, it can be returned within the 45 days warranty period. One of the best features of Fitbit is that if you lose it (say, while jogging) and it is recovered and returned to Fitbit, the business will search up the registered owner of the device for return details.

My Final Verdict on the FitBit Flex 2 Wireless Activity Tracker

I’ve been testing out the new FitBit Flex 2 Activity Tracker for the past few weeks. I’m a huge fan of the original FitBit, so naturally, I was excited to try out their newest model. The Flex 2 is not only smaller and more fashionable than its predecessor.

But it boasts all-day activity tracking in addition to its sleep tracking capabilities. The only issue I found is that FitBit flex 2 won’t sync and is not as accurate as some of its competitors out there. It tends to overestimate some of your steps and under-count others. But overall, it’s a good investment!
