List of Fitbit products

Fitbit Zip

A white Fitbit Zip, showing the distance in miles covered by the wearer.

Announced on September 17, 2012, the Fitbit Zip is about the size of a United States quarter and tracks steps taken, distance traveled and calories burned. It is able to sync its data wirelessly to supported mobile devices.^[1]

Fitbit Flex 2

Released in 2017. It is waterproof and can track swimming. The tracker can be worn in a wristband or pendant, or carried in a pocket. The LED lights function similar to the original Flex, with the number of illuminated dots indicating progress toward the set goal. It features "reminder to move" alerts and vibrations when a call or text is received.

Fitbit Alta

The Fitbit Alta^[2] was released in February 2016. The wristband offers a full OLED screen that can be tapped for reminders, a clock and smartphone notifications. While not a touch screen, it is interacted with by tapping the band, similar to previous models. The Alta is also able to recognize the type of activity in progress: running, football or walking.

Fitbit Alta HR

Fitbit Alta HR fitness tracker wristband showing heart rate monitor display.

The Fitbit Alta HR was released in March 2017. It has an added heart rate monitor. It includes the new Sleep Stages feature, which intends to show the stages of sleep, rather than just time asleep as in previous versions.

Fitbit Ace

Released in 2018, the Fitbit Ace is a variant of the Alta for children 8+ years of age.^[3][4]

Fitbit Charge 3

Fitbit Charge 3 displaying Time, Heart Rate, and Steps.

The Fitbit Charge 3 was released in October 2018. It has a heart rate sensor as well as an oxygen saturation (SPO2) sensor.

Fitbit Ionic

The Fitbit Ionic in workout mode on Fitbit OS 1.0.

The Fitbit Ionic^[7] was released in late September 2017. Designed to compete with the Apple Watch Series 3, it is the successor to both the Blaze and the Surge. Like the Surge, the Ionic uses built-in GPS, using GLONASS to tap into global satellites and provide better accuracy when recording exercises, with the antenna being integrated into the watch case for a stronger connection. The Ionic also features SmartTrack, which auto-recognizes user activity and records it in the Fitbit app. The Ionic has interchangeable bands, including classic Fitbit bands, leather bands, and perforated bands for a more sport-like appearance, and the release mechanism has been modified to make swapping out bands easier. It is also water-resistant, making it safe to wear when swimming. Many of the Blaze's clock faces return, as do several new clock faces. New to the Ionic is the ability to load apps onto the watch itself such as AccuWeather and Starbucks, as well as an NFC chip that allows the Ionic to be used for credit card purchases at places that allow contactless payment. As a result, the tactile buttons on the Ionic have some new functions. When not in workout mode, the right side buttons now function as shortcuts for the leftmost two apps loaded onto the watch, while a long press on the left side button brings up Fitbit Pay as well as music and quick settings. The Ionic is shipped in three color combinations of the wristband and watch case: Charcoal & Smoke Gray, Slate Blue & Burnt Orange, and Blue Gray & Silver Gray.

In 2018, the Ionic was updated to Fitbit OS 2.0 alongside the release of the Versa. The most notable change from OS 1.0 is the addition of a new app called Fitbit Today, a much more intuitive and informative dashboard displaying the user's health and fitness data. It is accessible by swiping up from the clock face, while the notification tray is now accessed by swiping down from the clock face. In addition, a long press on the back button now opens up the music controls, payments, and the shortcuts screen, instead of just Fitbit Pay. In July 2018, Fitbit announced the 15+ Best Fitbit OS Apps for Travel, that can be downloaded in Ionic and some are also available in Versa.^[8]

Fitbit Versa

Released in April 2018, it has a square design with round edges, similar to the Apple Watch and Pebble watches. It retains most of the Ionic's features and interface. It is capable of tracking women's menstrual cycles. It does not have built-in GPS like the Ionic, instead using connected GPS like the Blaze.

There are two variants of the Versa; the standard edition and the Special Edition. The standard Versa comes in three color: Black, Rose Gold, and Silver. The Special Edition comes in two colors: Rose Gold with a Lavender band, and Graphite with a Charcoal band. They also include woven wristbands.

Fitbit Aria 2

Fitbit Aria 2 in black.

The Aria 2 was announced in August 2017 concurrently with the Ionic. The Aria 2 has been re-engineered for greater accuracy and easier Bluetooth setup. The Aria 2 also has personalized face icons and greetings, compatibility with more Wi-Fi networks, and has an increased weight tolerance of up to 400 pounds.

Fitbit Flyer

Sweatproof wireless earphones by Fitbit. Has noise isolation.^[9]

Fitbit Tracker

The Fitbit Tracker was a small black and teal device that could be clipped discreetly onto clothing and worn 24/7. It uses a three-dimensional accelerometer to sense user movement. The Tracker measures steps taken and combines it with user data to calculate distance walked, calories burned, floors climbed and activity duration and intensity. It uses an OLED display to display this and other information such as the battery level. It also measures sleep quality by tracking periods of restlessness, how long it takes the wearer to fall asleep and how long they are actually asleep.^[10]

A wireless base station is included to receive data from the Tracker and to charge its battery. When connected to a computer, the base station will upload data to the Fitbit website, where a number of features are available: seeing an overview of physical activity, setting and tracking goals, keeping food and activity logs and interacting with friends. Use of the website is free.

The Fitbit Classic tracked only steps taken, distance traveled, calories burned, activity intensity and sleep.

At the TechCrunch50 during the "Mobile" session on September 9, 2008,^[11] Fitbit received positive reactions during its panel from experts like Rafe Needleman, Tim O'Reilly, and Evan Williams who cited its wearability, price, and lack of subscription fees.

Fitbit Ultra

Fitbit Ultra activity tracker in teal clipped to pocket.

The Fitbit Ultra was announced on October 3, 2011.^[12] The new features included:

• an altimeter that measures elevation gain in terms of floors, with one floor roughly equivalent to ten feet
• a digital clock visible on the device's display
• a stopwatch that can be used to time activities
• randomized "Chatter" messages show when the Ultra is moved after sitting idle for a while
• new colors

The Fitbit Ultra is powered by a small lithium polymer battery.^[13]

The Fitbit Ultra suffered from a small design flaw: the unit had a permanently curved shape in order to clip directly onto any piece of clothing. The plastic used in the unit was not appropriate for the strain experienced at the looped end, and with time would become brittle, and crack. While most users experienced only minor cracking with no effects to the device's function, in a few cases the cracking led to total failure.^[14][15][16] Fitbit offered replacement or repair of affected units that were under warranty.

Fitbit One

Announced on September 17, 2012, the Fitbit One is an update to the Fitbit Ultra that uses a more vivid digital display, has a separate clip and a separate charging cable and wireless sync dongle.^[17] The Fitbit One and the Fitbit Zip were the first wireless activity trackers to sync using Bluetooth 4.0 or Bluetooth SMART technology. The wireless syncing is currently available on iOS and Android devices such as the iPhone 4S and higher, iPad 3rd generation, iPod touch 5th generation, Samsung Galaxy Note II and higher, Samsung Galaxy S III and higher, LG G2, HTC One, Moto X, and Nexus 4 or higher.^[1] Fitbit One can record several daily activities, including but not limited to, number of steps taken, distance traveled on foot, number of floors climbed, calories burned, vigorously active minutes, and sleep efficiency.

Fitbit Flex

Fitbit Flex with accompanying wristband.

In May 2013, Fitbit released the Fitbit Flex, the first Fitbit tracker worn on the wrist. It tracks movement 24 hours a day, including sleep patterns. It has a simple display of 5 LED lights that indicate the progress toward the goal number of steps walked in a day and vibrates to indicate when the goal has been reached. The sync functions are similar to the Fitbit One and Zip. The Flex is the most water-resistant tracker, though cannot be worn while swimming.^[18] It includes a specialized USB charger; the battery lasts 5–7 days, and it takes 1–2 hours to charge.

Fitbit Force

The Fitbit Force was announced on October 10, 2013. It has an OLED display^[19] that shows time and daily activity. The Force tracks a number of statistics in real-time, including steps taken, distance traveled, calories burned, stairs climbed and active minutes throughout the day. At night, the Force tracks sleep and can wake a user silently with a vibrating alarm.

On January 13, 2014 it was reported that an unconfirmed number of Fitbit customers had complained about skin irritation after wearing the Force for extended periods of time.^[20] Fitbit stated on its website that the company consulted with medical professionals whose assessments are that these irritations are most likely allergic reactions to nickel, a component of the surgical-grade steel or the adhesives used to assemble the Fitbit Force.^[21] Fitbit, working with the Consumer Protection Safety Commission, recalled the Fitbit Force on February 20, 2014.^[21] On March 12, 2014 the Consumer Product Safety Commission (CPSC) made the recall official.^[22] At that time it was revealed that The Fitbit Force had caused about 9,900 injuries.^[22] It is no longer for sale on Fitbit's website.

Fitbit Charge

Announced in October 2014, the Fitbit Charge is intended as a replacement for the recalled Fitbit Force. It was released in November 2014 for US$130 retail. The Charge's wrist band is textured and has a screen that can display caller ID information from a connected smartphone through the Fitbit app. The Charge automatically tracks users' steps, sleep, flights of stairs (using an altimeter) and an approximation of distance traveled. It tracks steps using a 3 axis accelerometer by tracking forward movement along with upward movements.^[23][24]

Fitbit Charge HR

Fitbit Charge HR.

Announced in October 2014 and released in early January 2015, the Charge HR is similar to the Charge, with an additional heart-rate monitor. With this addition, the 7-day battery life is reduced to 5 days. The Charge HR has the same textured band as the Charge and comes in black, plum, blue, tangerine, pink, and teal colors. The Charge HR band clasp resembles that of a traditional watch instead of the snap-on band of the original Charge, as the band needs to fit tightly for the heart rate feature.^[25][26][27]

Fitbit Charge 2

The Fitbit Charge 2 featured a new multi-sport mode allowing users to start workouts from their Fitbit. Compared to its predecessor it had a larger screen.

Fitbit Surge

Fitbit Surge.

Announced in October 2014, the Surge was a smartwatch and an activity tracker. It features a heart-rate monitor and the ability to track pace, distance, and elevation using the GPS on the device. The Surge also can send alerts of text and incoming calls from a connected smartphone.

The Surge was discontinued in late 2017.

Fitbit Blaze

Fitbit Blaze.

Released in January 2016^[28] the Fitbit Blaze is a smartwatch made to compete with the Apple Watch, Pebble, and Android Wear. The Blaze comes with a colored touchscreen, and exchangeable strap and frame. It can auto-tracking exercises and has a heart-rate monitor. Blaze has connected GPS,^[29] meaning it tracks location using the connected smartphone's GPS. It can display notifications, including incoming calls, texts and calendar appointments.^[30] The Blaze introduces the Sleep Stages feature.

The Fitbit Blaze also integrates with Fitstar, Fitbit's website for customized workouts. These workouts can be displayed on the Blaze's screen.^[31]
