Fitbit Flex review

Couple of weeks ago I switched to Fitbit Flex from Fitbit Ultra, and here’s what I have to say about it.

Fitbit what?

Fitbit has been around for a while now. It’s known for the activity trackers, wireless-enabled wearable devices that measure data such as the number of steps walked, quality of sleep, and other personal metrics.

Fitbit makes it easy put your everyday routine to work toward your fitness goals. The highly accurate 3D motion sensor measures steps, calories burned and distance traveled. You can view your results in real time right on the tracker, or wait until they’re uploaded to the website. The tracker will always give you a clear sense of how you are doing and encourage you to do more. The more you know, the more motivated you’ll be.

Fitbit offers a free website with an extensive dashboard that can be used with or without the racker. Users have the ability to log their food, activities, weight, blood pressure, heart rate, and glucose levels to track over time. They also have the ability to set daily and weekly goals for themselves for steps, calories burned and consumed, and distance walked.

FitBit Ultra Stats

Many people appreciate this kind of gadgets, because seeing you life stats and knowing how close you are to reaching your goals gives you the motivation to reach them and aim higher.

Fitbit’s closest competitors are Jawbone and Nike+ Fuelband. Currently Fitbit offers four models with the average price between $60 and $130.

2011: Fitbit Ultra

The first model, Fitbit Classic, was released in 2008 and three years later it received a significant hardware upgrade.

Fitbit Ultra (2011) was able to use in-built altimeter, stopwatch along with other features.

I’ve been using FitBit Ultra since February 2012. It has been amusing and exciting for a long time, though I wasn’t able to use it constantly.

First, it had to be synced via the USB, so you had to take it off and plug into a laptop to see the renewed stats.

Second, there wasn’t any obvious way to wear it with all kinds of clothes, as it hasn’t been integrated into any wristband yet. There was an armband slip for workout time, but in daily life remembering to put it on was sometimes harder, then I expected.

2013: Fitbit Flex

Comparing to the first model, it’s obviously, a better experience. It’s way more wearable in daily life, it fits comfortably around the wrist so you can wear it all day and night and it’s easy to get used to its presence.

It syncs wirelessly with any laptop and most smartphones, so there’s no need to plug it in to check the stats. There’re both iOS and Android apps to check your stats any time.

Your daily progress is also visible on the band itself. When you tap it once the dots show you the day progress. When you reach the goal, all the dots light up and it lightly vibrates once.

Fitbit Flex is the first water resistant model, so you don’t have to take it off while swimming or taking a shower. I also love the fact that it notifies me when I need to charge the battery (once in a couple of weeks).

There is a huge enhancement in tracking the sleep hours. While you to wear it all night it’s measuring your sleep quality. In the dashboard you’ll see how often you wake up and how long you slept. Over time, you can use this information to understand what helps you sleep better and track your progress.

Fitbit Flex has an in-built silent wake alarm that gently vibrates to wake you at your desired time.

It comes with free online tools and a mobile app that allow you to set goals and follow your progress through neatly designed graphs and charts. Additionally, you can manually log food, workouts and much more and get the inside scoop on your health. Fitbit works with several popular health apps that let you export your data their way. Some, like Lose It!, also let you import their data into your Fitbit dashboard, so you can track your stats in either location. I’m mostly using it with RunKeeper.

Fitbit Flex is separate from the wristband, you can take the tracker out and put into any of Flex’s colorful bands to fit your outfit. this also makes it more durable. If you managed to damage the band, you can easily replace it with the new one.

I enjoy Fitbit Flex a lot. It’s way more comfy and wearable then the previous model I used to have. It syncs wirelessly with various devices, so you don’t have to take it on and off too often. It’s water resistant and because of the changeable rubber band it’s more durable then other trackers. It alerts you when you need to charge it (once in 1-2 weeks). The daily progress is visible on the wristband itself, and the full stats report is accessible from the iOS and Android mobile apps as well as on the website.

I would love to use it as a wristwatch, which is already offered in the Fitbit Force model, but I appreciate the changeable bands and water resistance feature more (Fitbit Force is completely integrated into the band with no way to remove it). The price is competitive, and from my point of view, Fitbit is the best activity tracker currently avaliable on the market. However, I’ve never had chance to test Jawbone or Nike+ Fuelband for a versatile comparison.

I’m surely happy with Fitbit and I would recommend anyone trying it for themselves.
