Fitbit has a family of full-featured pedometers, fitness band activity monitors, and smartwatches that track steps, distance, and calories. Fitbit activity trackers work with apps for most mobile phones, plus PC and Mac for those who don't have a smartphone. You can enjoy graphs and charts of steps, active steps, distance, sleep quality, diet, and other health statistics.

You can allow your Fitbit to share its activity data with many other apps and fitness tracking sites. All Fitbit models feed into the same personal profile web page and work with the Fitbit app. You can switch from one to another if you happen to have a couple of models. Explore a rundown of the different models in the Fitbit family.

Fitness Bands

If you prefer to wear your Fitbit on your wrist, these models can work for you:

  • Fitbit Alta: The Fitbit Alta has Move Reminders and step goals of 250 steps each hour (two to three minutes of walking). It has automatic exercise and sleep recognition. It has great style with interchangeable bands, with many options available from third-party vendors. You can read scrolling text, call, and calendar notifications on the band. It has a 5-day battery life.

  • Fitbit Alta HR: Same great style as the Alta, but it includes wrist-based heart rate so you can see your resting heart rate and which exercise zone you are in when working out. It will also have detailed sleep data for you and a 7-day battery life. You can use the same interchangeable bands as the Alta.

  • Fitbit Charge 2: This model replaced the Charge HR and Charge. It has a large display so you can use it as a pedometer watch, including reading text messages, calendar alerts, and caller ID. It has PurePulse heart rate, move reminders, sleep tracking, and advanced exercise tracking. It can link to your phone's GPS to track speed and distance. The Charge 2 has an interval workout mode, great for run/walk intervals or circuit training. It even has a guided breathing feature for relaxation. It also features interchangeable bands so you can switch up your style swiftly and easily.

  • Fitbit Charge 3: The Fitbit Charge 3 debuts in fall of 2018. It is slimmer and sleeker than the Charge 2 but has a larger display. One big advantage is that it is waterproof to 50 meters so you can wear it swimming and it will track swimming as an exercise. It has 15 goal-based exercise modes so you can get feedback during your workouts. It automatically recognizes different exercises. Women can use the female health tracking feature and ovulation predictor. It retains all of the other popular features of the Charge 2.

  • Fitbit Flex 2: This is the first waterproof model for Fitbit. Now you can take it swimming. It is thinner than the original Flex and has move reminders. It still has only five lights to signal your progress to your daily goal. You can customize it with a variety of bands or wear it in a pendant. It has automatic exercise tracking, including swim tracking.

  • Fitbit Ace: This is Fitbit's first band designed for kids ages 8 and up and is much like the Alta but with kid-friendly features. It tracks steps, active minutes, and sleep and has move reminders. Parents set up a family account and then create an account for their child. This allows parents to see their child's activity and progress. When the child reaches goals and milestones there are celebration messages on the band and badges are earned. It is showerproof.

Waistband/Pocket Styles

The original Fitbit models were designed to be won on the waistband or carried in your pocket rather than worn on the wrist, and that option remains for a couple of Fitbit models:

  • Fitbit Zip: The Fitbit Zip is the least expensive Fitbit model. It has a long-lasting 9-month battery that doesn't require recharging. It lacks tracking for stairs and sleep quality, and it doesn't have a stopwatch or workout tracker function. Because it uses the same phone app, you can use the workout tracking functions included in the app instead. If you're going off the grid, it's a good choice to wear when traveling. It will keep detailed info for seven days without syncing, and 23 days of daily totals without syncing. You can buy third-party holders to wear it in other ways than on your waistband.
  • Flex 2: This model can be removed from its bracelet and worn in a bangle, pendant, or a third-party clip.


These Fitbits are designed as smartwatches, with additional functions beyond fitness tracking:

  • Fitbit Versa: This smart fitness watch debuted in 2018. It is swim-proof and tracks heart rate in more than 15 exercise modes, plus on-screen guided workouts. It has interchangeable bands. It connects to your phone GPS for speed and distance. A variety of apps are available to enjoy it as a smartwatch. It stores over 300 songs and can sync with Pandora stations to send to your Bluetooth headphones.
  • Fitbit Ionic: This smart fitness watch has interchangeable straps, built-in GPS, heart rate, personal coaching, stores and plays music and Pandora stations, and works with Bluetooth headphones. It is water-resistant. It displays sleep stages, resting heart rate, and cardio fitness level. It will run popular apps and you can use it to make instant payments.

Discontinued Models

These models have been discontinued. In some cases, you may still see them for sale by retailers or online. Your activity history is maintained when you switch to a new Fitbit.

  • The original Fitbit Tracker and the Fitbit Ultra have been retired. They did not have Bluetooth for syncing with mobile apps.
  • Fitbit One: The One was a waistband clip model that also tracked floors climbed and sleep and it had a stopwatch function. It was discontinued at the end of 2017.
  • Fitbit Flex: This model quickly became the most popular wristband activity monitor, made to be worn both day and night to track all-day steps and sleep quality. It was discontinued in 2017 and replaced with the Flex 2.
  • The Fitbit Force wristband model was recalled in February 2014 because the exposed metal connector triggered allergic contact dermatitis in a small percentage of users.
  • The Fitbit Charge and Fitbit Charge HR were discontinued as of early 2017 and was replaced with the Charge 2.
  • Fitbit Surge: This superwatch included GPS, music control, and heart rate tracking with simplified heart rate zones. In exercise mode, you could see splits and other advanced workout tracking, and it will track other exercise activities. It was discontinued in 2017.
  • Fitbit BlazeThis fashionable smart fitness watch was discontinued in March 2018 in favor of the Versa and Ionic. It had many of the features of the Surge but it used your mobile phone's GPS rather than having it built-in.

Are They Waterproof?

Only the Fitbit Charge 3, Fitbit Flex 2, and Ionic are water-resistant enough for swimming. Other Fitbits are water-resistant so you can wear them in the rain or while washing the dishes, but they are not waterproof for swimming and may not survive a trip through the washing machine.

Setup and Getting Started

When you buy a Fitbit, there is no additional fee to use the website or mobile app. There is an optional fee per year for a Premium membership which includes more in-depth reports and personalized training. However, the basic reports seem more than adequate.

You can do all of the setup with the Fitbit app for iOS or Android on a Bluetooth-capable mobile phone or device. But you can also set it up and sync with a computer. The Fitbit comes with a USB stick which uploads data wirelessly if you are using a computer to sync. On first use, you install the Fitbit Service Manager software and register for the Fitbit website, and set a few basic bits of information about yourself. Your weight is needed to calculate your calories burned. The data automatically uploads any time you are within about 15 feet computer, you never have to remember to do it.

To upload away from home you can use the mobile app or you will need to use a computer on which you can install the software and which has a USB port.

Syncing With Mobile App

If you don't have a computer, you can simply use the free iPhone/iOS app or Android app to set up your Fitbit and sync your data via Bluetooth. With the app, you can also add food tracking and track non-pedometer activities. You can choose all-day sync or to sync on demand.

Your Dashboard

The dashboard tiles are a quick view of your activity, and you can select to see more details, including graphs of the past week, month, or year for each item.

  • Steps, Distance and Active Minutes: A pie chart and a graph of steps and activity every five minutes are displayed. It totals steps taken, distance, all-day calories burned and active minutes. You can review the current day, past 7 days, and past 28 days on the chart, and review each day in detail.
  • Calories, Food Logging, and Weight: The calories displayed are all-day calories rather than just exercise calories. If you choose to use their food-tracking capability, you can balance the calories you eat with those your body burns all day. You can set a daily calorie goal and see how you are progressing throughout the day. You can track your weight, and if you buy their Aria wireless scale your weight can be automatically logged.
  • Sleep: Most Fitbit models include sleep tracking (the Zip doesn't). Wear the Fitbit to bed and depending on the model it will either detect sleep or need to be put into the sleep-tracking mode. You can also manually enter your sleep data on the web site or app. It displays time in bed, times awakened, and time restless. Switch to the Log view and sleep tab and see your sleep stats in more depth, including sleep efficiency score, time to fall asleep, and stats for the past 30 days.
  • Friends: If you have friends who use a Fitbit, you can see how you compare with them for steps, distance, active points and very active time. You can also join groups and compare yourself to the group.

Fitbit Logs

In addition to the data from the Fitbit, you can manually enter other exercise activities, weight, and sleep.

  • Food Log: The food log is easy to use as a food diary. Once you enter a food, it adds it to a quick pick list. It also allows you to create your own "food" if it isn't already on the list of 50,000 different foods, so you will have it available to choose from for future meals. You can create meals so you can easily add them to your daily log rather than adding one food at a time. You can use the iPhone app to add food and activities to your log throughout the day.
  • Activities: You can add other physical activities you did and you can edit your walking step record for those times you forgot to wear your Fitbit. You can save your favorite workouts to quickly add from a pick list.
  • Weight: You can track your weight and body fat. If you use their Fitbit Aria wireless scale, these can be added automatically.
  • Apps and Integration with Other Programs: The iPhone app and Android app let you update the food and water you have throughout the day and log exercise and activity that Fitbit doesn't track (such as cycling or swimming). Fitbit can integrate data with Microsoft HealthVault, Endomondo, and Nike+ as well as several other tracking systems.

Bottom Line

Fitbit has become synonymous with activity tracking. The models are easy to wear and super easy to use. The website has no additional fees. They work both with PC and Mac and Bluetooth-capable mobile devices. The Zip is less expensive but doesn't include sleep tracking or stair climbing.
