What is a Fitbit?

Fitbit Charge 2 - 1

Welcome to the Fullfitnez review of Fitbit. This article will provide you with all the basic information you need to know about the worlds most well-known fitness and activity tracker. If you find yourself here you have likely already asked ‘What is a Fitbit?’ So let’s find out.

Fitbit, Inc designs and produces a range of activity trackers, watches and other accessories that use wireless-enabled technology. These are also commonly known as ‘fitness wearables‘ and are devices that monitor and measure the wearers personal activity data such as the number of steps walked, performance during exercise, heart rate, quality of sleep, steps climbed, and other personal metrics related to health and fitness.

According to an IDC report published on December 3, 2018, Fitbit is considered the third largest wearable company in shipments as of the third quarter of 2018, behind Xiaomi and Apple.

Fitbit was founded by James Park CEO and Eric Freidman CTO on 26th March 2007 in Delaware, United States of America. It’s headquarters are now in San Francisco, California, United States.

What is a Fitbit For?

A Fitbit is a personal activity tracker or wearable device usually worn as you would a watch, although some can be fitted in belt clips. Throughout the day, it logs a range of data about your activities and general health and encourages you to obtain, maintain and improve a healthy lifestyle.

What Does a Fitbit Do?

Primarily It tracks the amount of activity take each day in the form of steps, and monitors your heart rate in conjunction with this. I own a Fitbit Charge 2 and on this and the latest Fitbit devices you can quickly view this data in real-time by simply tapping the device face twice to illuminate the screen where these two statistics will be displayed.

Tap again to see the distance those steps have covered in either miles or kilometers and the current amount of calories you’ve burnt that day. Tap a fourth time to see how many floors you’ve climbed and how many ‘active minutes’ the device has detected you completing.

Active minutes are achieved through daily activities of all kinds such as housework or DIY even, but being on your feet with a raised heart rate will log these. When sync’d with your phone you can also receive notifications of texts received, incoming calls and calendar reminders on the Fitbit screen.

This is just the tip of the iceberg however as when used with the Fitbit app, Fitbit not only tracks steps, heart rate and the data already mentioned, but your sleep, weekly exercise sessions, weight, hydration, calories consumed and even female health. Depending on the Fitbit device you use will enable more or less of these features.

The Fitbit Charge 2 contains the following sensors; A MEMS 3-axis accelerometer, which tracks your motion patterns. An altimeter, which tracks altitude changes and an optical heart rate tracker.

This might all sound complicated to some but the beauty of Fitbit is that it can be used to simply log your daily step count or to keep a close eye on your heart rate at any moment. Another simple and interesting feature is being able to monitor your own sleep quality and see more detailed statistics on this. You can also log minutes spent doing household activities including gardening.

However If you love your exercise then a Fitbit will cater for all your needs. You’ll love how your Fitbit and the app can track all you do and even where you do it with GPS, and provide you with a range of stats, graphs and figures that relate to your chosen activity and performance. It will recognise a range of exercises automatically by detecting you taking part in them and also allows you to manually input more including sports and exercise classes from Archery to Zumba.

Fitbit wasn’t created for fitness fanatics alone, the creators vision is to educate that ‘fitness is not just about gym time. It’s all the time’ and that all your steps add up to much more.

Fitbit App Mediocre

The Fitbit App Dashboard displays all your daily data. Leave the app ‘open’ on your smartphone to view your current stats at a glance. My main goal is steps as you can see. You can set yours to floors, miles (or km), calories or active minutes.

Sync With Fitbit

To fully utilise your Fitbit you need to synchronize it with the Fitbit Mobile app on a smart phone and create an account. The app is available to download for Apple devices operating iOS 10 and higher, Android devices operating OS 5.0 and higher, or Windows devices operating 10 v1607 or higher, so you’ll likely be able to use your Fitbit with your current phone, top brand devices from Apple and Samsung and the latest, but no less powerful budget smart phone options. This is easily done following the instructions provided with each new Fitbit. You can also set up more than one Fitbit on your app.

Fully Utilise Your Fitbit With The Fitbit App

When sync’d to your mobile phone you’ll be asked to input some basic data about yourself as part of the set-up process such as your gender, age, height and weight. Then your Fitbit will be able to track all the data we’ve already talked about in amazing and informative detail.

It will also do more such as tracking different types of exercise and activities, logging food, and weight. This can be extremely interesting and educational and is best done consistently over time and is even more accurately measured when users continually wear their tracker, yes even when sleeping which took me a while to get used to.

The Fitbit Dashboard

Once your account is up and running you can access your Fitbit Dashboard in the app on your mobile device or by logging into your account on your computer to see real-time stats on your daily activity.

The Dashboard and app are also the gateway to the Fitbit community where you can post your current activity or status, find friends that also use Fitbit, read fitness related news, find local events and discover and join groups based on various types of fitness and activities. You can also communicate with friends and others by sending messages or posting comments much the same as on other social media platforms.

Daily Activity

On the home screen view your all-day activity of steps, distance, exercise, calories burned and more. Using your Fitbit, track your sleep and use Sleep Tools in the app to set goals, targets and reminders and review your sleep trends.

It’s possible to connect multiple trackers to one account and the Fitbit app cleverly detects when you switch between them so you could use a Fitbit Ionic during workouts and discreetly wear a Fitbit Inspire in a Clip Accessory to track your day.

MobileTrack – If you don’t have a Fitbit tracker you can still track your day using only your smart phone and the Fitbit app to track basic stats such as steps, distance and calories which is maybe worth doing if you’re wondering about buying a Fitbit tracker.

Activity & Workout Tracking

Use a Fitbit tracker to record workouts that are then sync’d to the app or log them manually in the app or change the activity or exercise type. View your stats including calorie burn and heart rate and how they impact your day and see your performance improve over time.

MobileRun – By using the Fitbit app on your smartphone to track pace time and distance with GPS can add an exciting dimension to runs and walks enabling you to see an overview of your performance and route. This feature also allows you to control your music through the Fitbit app and use voice cues such as spoken distance and mile markers whilst on a run and credit for steps taken and calories burned.

The Fitbit Account

Within your account settings on the Fitbit app is where you can view and set personal parameters such as goals, manage personal settings, discover other compatible apps that sync data with Fitbit, use the Fitbit help section and manage account security, privacy and notifications. Here you can really tailor all your health and wellbeing requirements in detail, or allow Fitbit to set them for you based on your personal metrics.


Activity – Set daily activity goals in steps, distance, calories burned, active minutes, floors climbed and hourly activity.

Fitbit automatically recognises a number of exercise types using its SmartTrack technology including walking, running, biking and aerobic workouts.

You can also log these and many others manually.

I use the MyFitnessPal app to log my daily calorie intake and in this I can see current calories burned in real time and this data is provided by my Fitbit. You can choose from fitness tracking apps, games and rewards apps, apps for weight loss, wellness and more.

He wasn’t wearing Fitbit but some other brand though it’s the same technology. It’s fantastic to see how much this small gadget can change the lifestyle of a person. I’ll definitely take Fitbit into more serious consideration.
