Fitbit is a family of full-featured pedometers, fitness band activity monitors, and smart watches 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. Here is 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: This model 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. See the full Fitbit Alta review.
  • 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 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.

    • Fitbit Surge: This is a superwatch that includes GPS for speed, distance, and route tracking. It has caller ID and music control.

    • Fitbit Blaze: This is a fashionable smart fitness watch  You can change straps in seconds to dress it up or down. It has many of the features of the Surge but it uses your mobile phone's GPS rather than having it built-in. In addition to the usual Fitbit steps, distance, calories, floors, it automatically records workouts with heart rate and heart rate zones. You can also start FitStar workouts on your wrist, control your music, and get smart notifications. Move reminders prompt you to move and show a countdown towards 250 steps per hour. It has a 5-day battery life before recharging.  Buy from Amazon.com

      Waistband/Pocket Styles

      These Fitbit models can be worn on your waistband, neckline or carried in a pocket, purse or pack. They aren't fussy about being worn at an angle and will sense your steps and activity in any position. They have a numerical display you can check anytime to see your steps, distance, all-day calories burned, and time of day. These Fitbits are small, silent and lightweight.

      • Fitbit One: The One also tracks floors climbed and can track your sleep and it has a stopwatch function. It needs to be recharged every 7 to 10 days. See the full review of the Fitbit One
      • Fitbit Zip: The 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. It's a good backup Fitbit to have for those sort of trips.

      Discontinued Models

      • The original Fitbit Tracker and the Fitbit Ultra have been retired in favor of the Fitbit One. They did not have Bluetooth for syncing with mobile apps.
      • 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, replaced with the Charge 2. These models didn't have interchangeable wristbands, while the Charge 2 has that advantage.

      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 at all, 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.

      Are They Waterproof?

      Only the Fitbit Flex 2 is waterproof. Other Fitbits are water-resistant so you can wear them in the rain or while washing the dishes or your dog, but they are not waterproof for swimming and may not survive a trip through the washing machine. The Surge and the Charge HR can survive immersion if you happen to drop them into the pool (or, shudder, the toilet). But they don't guarantee them for the pressures they would encounter swimming (or in the laundry).

      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.

      Discontinued: Fitbit discontinued manual entry of blood pressure, heart rate, body measurements, glucose, journal and custom trackers as of August 27, 2015.

      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. Fitbit Apps

      Bottom Line

      Fitbit has become synonymous with activity tracking. The models are easy to wear and super easy to use. The web site 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.
