Comparison: flexible fitbit or pay fitbit - which is the better choice?

Last updated on 2. August 2020

Fitbit has made a name for itself by selling portable fitness tracks that can be purchased at an affordable price. These bracelets count the number of steps you take each day and keep track of your sleep pattern each night, with results so you can easily check your condition.

The device has proven to be an unparalleled tool for people who want to achieve certain physical goals or for people who simply want to achieve an overall improvement in their health.

Fitbit has a range of tracking devices, but the two most popular models are the Fitbit Flex and the slightly newer Fitbit Charge HR. Each of these products will help you control the quality of your daily activities. However, there are some differences between the two devices.

To help you overcome this dilemma, both devices have been carefully studied and a detailed overview has been drawn up by comparing important aspects, such as available functions, battery life, design, price and much more. If you’re lucky, the following will help you better understand the pros and cons of each model.

Core functions shared by both units

The Flex and Load reports show your daily activity level. Both of them:

  • Calculate the number of steps you take
  • Calculate the distance travelled
  • Calculate the calories burned
  • Pay attention to your standby mode.
  • The vibration alarm wakes you up at the right time in the sleep cycle.
  • Automatically syncs with the Fitbit application on your smartphone and/or computer

What does the Fitbit Charge add compared to the Flex?

In addition to these functions, Charge has a number of other Smartwatch functions or special fitness bells and whistles that were not found in the old Flex.

  • If you want to view the results of
    with Flex, you need to use the application on your smartphone or computer to view the measurements. At Batch, on the other hand, you can view the results throughout the day simply by looking at your wrist.
  • Caller ID
    The charger has an additional Caller ID function that allows you to see who is calling without reaching the phone. It was added to protect people from unwanted interruptions. However, you cannot pick up the phone with the bracelet.
  • Tilt
    Flex can count the number of ladders you climb, but does not detect inclined surfaces. Walking on a hill burns more calories than walking on a flat surface – this is taken into account when recharging; this is not the case with the Flex.
  • Instant Sleep Results
    The charge indicator has an automatic sleep detection function that knows when you wake up and immediately indicates if you slept well during the night. With Flex, you have to wait as long as it takes to get to your phone to see the results.

one-to-one – highlights


The Flex screen is very simple and easy to use as the smallest fitness tracker. There’s a thin screen with small LEDs that light up to see the overall progress you’ve made towards your fitness goals. Each light represents 20% of your target. However, for more information, please contact your computer or smartphone.

Charge’s OLED display is a little more technical. The LCD screen can display the exact numbers of each category you are working on. It will also inform you about the areas where improvements can be made to achieve the goals you have set for yourself. This means that it lets you know if you need to exercise more or burn more calories, which can be very useful for those who are trying to make some improvements.

Battery life

The length of time technical equipment can change from one load to another is often an important factor in many purchases, and fitness monitoring equipment is no exception. Both Flex and Charge are equipped with lithium polymer batteries that are fully charged in one hour and both use USB cables for charging.

The Flex is charged for 5 to 7 days, while the charger can continue to charge for 7 to 10 days.


Watertightness is also a very important factor in the choice of the Fitbit. It is likely that you will wear the device during training, which can mean a lot of sweat.

Fortunately, both the Flex and the Charge are waterproof and can be submerged to a depth of 33 feet without a short circuit. The Flex can stay under water longer, because a long dive disrupts loading times. However, experts strongly recommend that you remove all physical fitness markings before freediving or diving.

Neither the charger nor the flex can control swimming activity.

Both appliances can withstand minimal contact with water, such as sweat, splashes, washing up and showering. However, Mr. Fitbit warns that regular and/or prolonged contact with water may weaken the rubber belt and possibly cause the machine to smell.


The Flex cuff is made of flexible material and has a standard closure. It is available in ten different colours. The Flex is thinner and lighter than the Drawers.

The conveyor is wider because it has a larger screen. The buckle, which resembles a loop, is specially designed to prevent complaints that the soft buckle is sometimes not kinked. The belt is also made of rubber and has a structured design. It is available in four different colours.

Both bracelets are soft and durable. It is important to note that neither Flex nor Load causes eruption problems, which led to the massive recall of the Adjustment Force. Fitbit asked Harvard’s experts to create a target group with a high resistance to skin irritations.

The company continues to inform owners of all Fitbit models that perspiration can cause irritation for more than two hours and that the device should be washed before reattaching.


  • The Flex is thinner and lighter than the Drawers. The bending width is 13.99 mm and the load width is 21.1 mm. Flex weighs 29 grams and the load is 30 grams.
  • Regarding the size of the bracelet, the Flex is available in two sizes: small (5.5 – 6.9 inches) and large (6.3 – 8.2 inches).
  • The rate is available in three sizes: small (5.5 to 6.7 inches), medium (6.3 to 7.9 inches) and large (7.8 to 9.1 inches).
  • The purchase of one of these devices includes a wireless sync key and charging cable. Flex and Charge are compatible with Windows and Mac operating systems as well as Android and Apple smartphones.


Last but not least, it’s time to think about the price. It is generally a factor that makes or breaks a purchase decision. Both fitness monitors are cheap. You can find cheaper counterfeit brands online, as well as more expensive trackers such as Apple watches. With Fitbit, you know you are buying a quality product through a proven online platform.

The charger is bigger and has more advanced features and is also newer. It is currently sold for about $120 (see this list for offers). In the meantime, the Flex is an older model and cannot do as much as the fee. It is currently sold for about $99 (see here).

Final analysis – Fitbit Flex vs. load ?

Both the Flex and the Charge are excellent fitness monitoring tools. When it comes to determining what is best, it really depends on what you expect from a health monitoring device.

For whom is the fee due?

For people who have serious goals for which they use Fitbit as a tool, HR Fitbit Charge is the right way to go. This gives you a more in-depth analysis in the field, which means you can literally follow your progress at every step.

In addition, the Caller ID function allows you to check who is calling and decide whether or not to answer the call without interrupting your training. I bought mine here because it’s often sold for less.

Who is FLEX for?

For people who are considering buying a Fitbit in the hope of improving their overall wellbeing, the Flex is the best choice. You can easily track your physical activity on your smartphone or computer. But the minimal character of Flex allows you to follow your activities without having to concentrate on the statistics.

People are overly attached to their mobile phones and obsessively check emails or updates on social networks. Flex saves you from another gadget so you don’t get stuck with it. It’s also cheaper and more fashionable. More information about the prices can be found in this list.

Flex and Charge both rank first in consumer ratings for superior performance and style. Each of these devices will help you improve your overall health, and that’s the most important thing. After all, you can’t make a bad buy.
