Fitbit is a family of full-featured pedometers/wellness monitors that track steps, distance, and calories. Fitbit monitors upload wirelessly to a web site or mobile app to enjoy graphs and charts of steps, active steps, distance, sleep quality and to track your diet, heart rate, blood pressure, glucose. The Fitbit One and Zip are worn on your waistband or in a pocket, while the Flex and Force are wristband monitors. They work with both PC and Mac and have no additional subscription fee to track your activity online. Fitbit has an iPhone app and an Android app and integrates with an increasing number of other apps and fitness tracking sites.
I found the Fitbit to be the best activity tracker I have reviewed so far -- small, quiet, convenient, with a full-featured web site included at no extra charge. All Fitbits feed into the same personal profile web page and work with the Fitbit app, although you can only use one at a time to update your online account. Here are the various models:
Fitbit One: This model debuted in late 2012. It uses Bluetooth to upload to a cell phone or tablet app, and can also upload wirelessly to a USB dongle. Review: Fitbit One
Fitbit Flex: This model is encased in a flexible wristband, to be worn both day and night to track steps and sleep quality. It has no display other than five small lights, so you are dependent on accessing the data on an app via Bluetooth or through the wireless USB connection and viewing your dashboard online. Review: Fitbit Flex
Fitbit Force: This wristband model was recalled in February, 2014 because the exposed metal connector triggered allergic contact dermatitis in a small percentage of users. It is no longer available for purchase. It had a numerical display for steps, distance, calories, and time of day. It will also track stairs and active minutes, in addition to sleep quality. Fitbit Force Recall
Fitbit Zip: The Zip lacks tracking for stairs, sleep quality or stopwatch. But connects directly with smartphones via Bluetooth (in addition to the USB connection to computers). It has a long-lasting button battery so you don't need to recharge it. Review: Fitbit Zip
Fitbit Ultra: This model debuted in 2011. The display is brighter than the original Fitbit, which is a welcome improvement. It also tracks stair climbing and has a stopwatch function. It is rumored that the Fitbit Ultra will be retired in favor of the Fitbit One.
Getting a Fitbit and Getting Started
When you buy the Fitbit pedometer, it includes use of the web site for no additional subscription fee. There is an optional fee per year for a Premium membership which includes more in-depth reports and personalized training. However, the basic reports seemed more than adequate for me.
The Fitbit comes with a USB base unit which both uploads data wirelessly and recharges the Fitbit's internal battery. On first use, you install the Fitbit Service Manager software and register for the Fitbit web site, and set a few basic bits of information about yourself. Weight is needed to calculate your calories burned. The set-up was easy.
The data automatically uploads any time you are within about 15 feet of the base unit, you never have to remember to do it.
To upload away from home you will need to use a computer on which you can install the software and which has a USB port, and bring along your base unit, or sync your data with the free Fitbit mobile apps.
The iPhone app and Android app let you add food and activity to your online log. You couldn't upload the step data with the original Fitbit Tracker or the Fitbit Ultra. Bluetooth has been added to the Fitbit Zip, Fitbit One, Fitbit Flex and Force.
Your Fitbit Dashboard
Your homepage includes:
Calories: Graph shows calories burned every five minutes, color coded for intensity. It also shows the calories you enter via the Food Log. You can review past days.
Activity: A pie chart and a graph of steps and activity every five minutes are displayed. It totals steps taken, distance, and an Active Score.
Sleep Efficiency: If you wear the unit to bed in its wristband or just clipped to your nightwear, and remember to start and stop it in sleep mode, it tracks your sleep pattern. This displays with a sleep efficiency score, when you went to bed, how long it took you to fall asleep, times awakened, how long you were in bed and actual sleep time.
Journal: You can track your mood each day, allergies and any custom log you want to keep (smoking, strength training, alcohol, stretching, anything). You can also journal information about the day.
My Stats: A weight tracking graph is shown. You can view 7-Day, 30-Day and All-Time Best for steps, calories burned, miles, active score, and very active minutes. You also see comparisons between you and all Fitbit users, updated weekly.
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.
In addition to the data from the Fitbit, you can enter other data onto the web site to track food intake, other exercise activities, weight, sleep, heart rate, blood pressure, and glucose. You can also add any custom tracker you wish to chart.
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. While I found their list less comprehensive than I would like, users can always use our free Calorie Count site to get calories for a recipe and then use that in the Fitbit food log. 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 in several ways. You can track pounds, body fat, and body measurements.
Heart Rate, Blood Pressure, Blood Glucose: Those who wish to track this data can easily enter it and view graphs.
Apps and Integration with Other Programs: The iPhone app and Android app lets you update the food and water you have throughout the day and activity, but it doesn't read the data from the Fitbit. You can see your Fitbit data that has been uploaded through your base unit. Fitbit can integrate data with Microsoft HealthVault, Endomondo, and Nike+ as well as several other tracking systems.

Update: Breakage and Improvements in the Fitbit Ultra
My original Fitbit Tracker succumbed to stress and simply fell apart after 15 months of wearing it most days of the week. The plastic elbow simply gave out. The warranty is only for 12 months. I could have avoided this breakage if I had used the provided belt clip holster rather using the Fitbit as its own clip.
The Fitbit One hasn't had the same breakage problem as it is a one-piece unit that slips inside a neoprene clip case that can be replaced. However, some people have had trouble with it popping out of the case and getting lost.
