Fitbit flex review and set up instructions

fitbit flex activity tracker

Well, I have had my fitbit flex for almost two weeks now, and I thought it was high time for me to write a review on the nifty little product.

I can’t tell you why it took me so long to get one of these considering my love for technology and my recent obsession with living healthy, but so far I am glad that I did.

Many of the reviews I have seen for the fitbit devices in general have claimed that they are really just a gadget designed to trick you into exercising so that you can fill in the icon for the day, and you know, I totally agree with them.

I think it was an awesome idea to turn fitness into a game, and for those that sometimes lack motivation (don’t we all at times?) this little item may be just what you have been needing.

There are many reviews out there, but I wanted to provide you the options that I really get the most use out of along with a full video walk through and fitbit flex set up instructions.

Why Use it?

Ok, so you have probably heard a lot about the suite of fitbit products, and you may be asking what this thing is really good for?

There are many valuable items this gadget provides, and I will cover them below, but in my opinion the greatest advantage I get from my flex is motivation. I am motivated to complete all of my tasks and fill in my daily charts.

Each day your fitbit app resets with a brand new set of goals for you that include how many steps to take, minutes you should be active, how much water to drink, and more. I have explained more about the goals feature below.


Daily steps goals can be updated based on your activity level to keep pushing you to get up out of your chair and walk your way to a healthier life.

The minutes active tracker shows you exactly how many minutes of the day you have been active. This task tracks actual minutes of exercise, but does not count walking back and forth from your desk to the copier.

Food plan goals can be set up based on how much weight you want to lose, and then allowing you to select the difficulty of the program based on how fast you want to lose it. You then log any food items you eat, and the program automatically calculates calorie intake vs calories burned in a day.

Sleep logger is an amazing sleep tracker that allows you to see how restful your sleep is each night. You can simple tap the sleep button to let the fitbit know you are going to sleep, and it will track how many movements and how extreme each movement was during the night.

Exercise tracker easily lets you store any work out or exercise sessions you had in a day. Each time you log a session the program automatically adjusts calories burned based on the intensity level of that exercise.

The daily water goal is one of my absolute favorites. I have a hard time remembering to drink water during the day, and this feature alone has helped me to increase my health by 100%.

Challenges aren’t really considered a goal tracking feature of the fitbit, but they are a great way to get you up and moving. By placing or accepting challenges with your friends you are automatically matched against one another to see who can complete the most goals with a day, week, or month. Nothing motivates like competition!

My fitbit flex video review


As you can see in the video, the fitbit flex arrives ready to use right out of the box with only a few steps to follow in order to get it up and running.

I found it very easy and had mine ready to go in about 5 minutes. In my opinion, this is one of the best features of the fitbit products as I would rather begin using my product than spend an entire evening trying to get it set up and working.

There were a few items that I did not get to cover due to resetting the application on my phone by mistake last week, and I hope to get an update out soon so that you can see how the logs track your progress.

Step by step setup instructions

The instruction card included with the fitbit flex is pretty easy to follow and should have you up and running in no time, but I wanted to post a step by step guide on the fitbit flex set up instructions.

First, open the box and determine the correct band size for your wrist. The flex is packaged with a small band and a large band. You can check the fit by placing the band around your wrist just as you would a watch.

Next you will place the fitbit into the correct sized band by sliding the sharp edged end of the fitbit into the side of the band that has the window for viewing the lights. Make sure that the arrow on the back of the fitbit is facing away from the band and towards you. Please refer to the video to see a walkthrough of this.

After securing the fitbit into the band place the band on your wrist just like you would a watch. It should fit just tight enough to allow one finger to pass between the band and your skin. (see video)

Download the app on your phone through Itunes Store or Google Store.

Follow the picture instructions on the app step by step.

You’re all done!

Ok great, now what do all of these lights mean?

This one had me pretty confused so I had to do a little research to find this. The fitbit flex basically has one tiny window that can display a series of four LED lights along with different vibration patterns on your wrist to notify you of battery life, reaching a goal, or the chip going into sleep mode.

The battery charge lights were pretty self-explanatory, but the first time my fitbit accidentally went into sleep mode I had no idea what was going on. I have provided a few pictures below for illustration purposes.

The number of lights indicate battery charge from 1 to 4 with 4 lights meaning the battery is fully charged and 1 light meaning you need to charge the battery. Shown above is a fitbit flex with a 75% charge of the battery.

For information on how to charge the battery with the attached USB charging cable please watch the video above. I have owned my flex for a little over a week now, and have only charged it one time after about 5 days of use. At the time that I charged it I still had 25% of my battery life remaining so I would guess that the battery should last you for about a week with normal use.

This configuration of lights above mean that the fitbit has gone into sleep mode and is usually accompanied by two short vibrations on your wrist and the lights dancing back and forth. In order to take the fitbit out of sleep mode simply tap on the front of the band 4 or 5 times.

You will know this worked when you feel another vibration and the lights blink and then show your battery charge for a few seconds before going blank again.

My plans for my fitbit flex

I have really been enjoying my time with the fitbit flex so far and really hope to get more use out of the features I have not yet really tried. I plan on spending some time over the next few days connecting with friends or other fitbit users to take part in the health challenges that are offered.

I really feel that this would be a great motivator, and I enjoy the social aspect of exercise.

Another of the feature that interests me is the log kept by the sleep tracker application. I plan on showing the logs to my doctor during my next annual checkup and am curious to see where that conversation may go.

Where can I buy the fitbit flex?

You can usually buy these at any of your major electronics stores both in the store and online. Best Buy, Walmart, and Target all stock fitbit products, but I have noticed that the prices vary quite a bit, and the fitbit flex is usually available in limited stock, but you can find them if you try a few different stores.

I bought mine on Amazon, and got it for less than I could find it in my local store along with same day delivery to my house. I have provided the link to the fitbit flex on Amazon below.









I hope you have enjoyed my review of the fitbit flex, and I look forward to any comments or questions you might have. Also, if you have a flex and would like to add me to your friends for challenges, please let me know by leaving a comment below!

Cheers to your health!



  1. That is the suitable blog for anyone who needs to seek out out about this topic. You understand so much its almost hard to argue with you (not that I actually would want…HaHa). You definitely put a new spin on a subject thats been written about for years. Great stuff, simply nice!

  2. Having read this I thought it was very informative. I appreciate you taking the time and effort to put this article together. I once again find myself spending way to much time both reading and commenting. But so what, it was still worth it!

  3. Hey Allan,

    Awesome review, I really liked your video as well. Even though you mentioned it’s for your first, you covered all the things needed. I have always been a health conscious person. but was never inclined to try out these stuffs. I am more into doing it the old fashioned way. But after going through your in-depth review on the product, you really got me interested on this stuff right here 🙂 I’ll be checking out this product for sure.


    • Thanks for dropping by Karthik! I am glad that you found the information here valuable, and I am glad you liked the video review. I definitely tried to cover all of the features I love about my fitbit flex, but there were a few items that I didn’t get to show since I had just reset the stats. I plan on providing an update after I get a little more data to fill up the logs so you might want to check back in a few days.

  4. I like the idea of a gadget designed to trick you into exercising. Sometimes it’s hard to get motivated. The fitbix flex would help keep you on track. I like the fact that it reminds you what you need to do, which takes almost all of the daily planning off your shoulders. This would make a great gift!

  5. Great and detailed review! Found it very informative and the way it was presented kept me interested. I also like how there was the video option too. Keep up with posts like this!

  6. Hey, great review. I learned a lot from your review.

    I have to say that I agree that sometimes a little motivation is a good thing. I know theres an old saying that goes like this “whats measure improves”.

    So basically that means that if we measure our heart rate, steps or fitness goals there is a better chance that we will improve them. I’m a firm believer of this and I can see that you are as well. Nicely done.


  7. Hey Allan!

    Funny you did a review on this..I’ve always been interested in the FitBit Flex. Not that I have issue with staying active, but it doesn’t hurt to have it keep you in “check” with your fitness goals lol. It also looks like something you can really have fun with. I’m especially intrigued with the sleep tracker!

    I really appreciate you breaking everything down. Your review helped me gain some clarity on the FitBit Flex!

  8. hi Allan
    love this fitbit flex review! Now I want one! I think that some of its features are awesome and so practical. To know your calorie intake vs how many you have burned? Great! And I like that it provides reminders. I usually exercise in the morning before the day goes away and busy. But I would need reminders to drink water for example throughout the day. and The Fitbit flex set up instructions seem very straight forward

    • Thanks for the comment Emily! It sounds like you and I have set up a similar schedule as I too like to exercise in the morning. I totally agree with you on the water reminder, it is what I use most!
