Fitbit, Inc.[1] is an American company headquartered in San Francisco, California. Its products are activity trackers, wireless-enabled wearable technology devices that measure data such as the number of steps walked, heart rate, quality of sleep, steps climbed, and other personal metrics involved in fitness. Before October 2007, the company was previously named Healthy Metrics Research, Inc.[3] Some evidence has found that the use of similar devices results in less weight loss rather than more.[4]

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.[5]


Health effects[edit]

In those who are overweight or obese, a 2016 study indicates that the use of wearable technology combined with standard behavioral interventions results in less rather than more weight loss after two years of use when compared to usual weight loss interventions.[4] There was no evidence that the devices altered the amount that people exercised or their diet compared to control.[4] It is unclear whether these devices affect the amount of physical activity children engage in.[6]

Alongside the activity trackers, Fitbit offers a website and mobile app for iOS, Android and Windows 10 Mobile.[7] The trackers can be synced to devices such as mobile phones via Bluetooth, or to a Bluetooth-equipped computer running Windows or MacOS. Users have the ability to log their food, activities, and weight, to track over time and can set daily and weekly goals for themselves for steps, calories burned and consumed, and distance walked. Calories in versus calories out are more accurately measured when app users keep their tracker on. However, the app can be used without a tracker to measure calories on a lifestyle app. The app offers a community page where users can challenge themselves and compete against other users. The social element anticipates an increase in motivation, finding that users take an average of 700 more steps per day when they have friends on the app.[8] Users can choose to share their progress pictures and achievement badges.

The first product released was the Fitbit Tracker.[9] The company released its Fitbit Iconic smartwatch in October 2017 for $300[10] and this was supplemented in 2018 by the Versa, a smartwatch with a revised design and a lower price.[11]

The Fitbit Charge 3, a wristwatch-like health and fitness tracker introduced in October 2018, was the first device to feature a oxygen saturation (SPO2) sensor – however, it is non-functional and Fitbit has yet to give a timeline for the feature to be enabled. This is creating significant customer backlash as of January 2019. The device has a touchscreen display, goal-based exercise modes and some smart features.[12]

The Fitbit Charge 3 comes with two different-sized bands: small and large. The small is around between 5.5 – 7.1 inches and the large is 7.1- 8.7-inches. Additionally, the screen is larger than the Charge 2 by approximately 40%. Fitbit Charge 3 comes in two color combos: a Rose-Gold case with a Blue Grey band and a “Graphite Aluminum” screen case with a Black band.[13]

On December 17, 2018, Fitbit announced Fitbit OS 3.0 – a version with an extended on-device dashboard, on-device quick logging for weight and water intake, and goal-based exercise mode. The new extended on-device dashboard (FitBit Today) will include more stats and data regarding sleep, water intake and weight.[14]

The new Fitbit OS 3.0 also includes Fitbit watch versions of fitness-related apps that are popular on platforms like Apple’s iPhone and Google’s Android.[15]

Fitbit also announced that ten new partner apps are being added to the Fitbit App Gallery. Couch to 5K, Achu health, MySwimPro, and Genius Wrist are added on December 17, 2018. Charity Miles, FitBark, Gold’s Gym, TRX, Mindbody, and Noonlight Emergency Services will be added by early 2019.[16]

On December 19, 2018, Emirates NBD announced its support of Fitbit Pay, providing services to the app. Emirates NBD is the first bank in the Middle East to offer this service. To enable transactions, customers need to add their credit cards or debit cards to their Fibit accounts. As Fitbit Pay uses NFC to transmit card technology, the users don’t have to authenticate via chip or pin.[17]

On December 20, 2018, Fitbit announced that it is adding a Run Detect feature, enabling auto-pause and auto-stop. Additionally, Fitbit is adding a new birdie goal celebration and New Clock Faces to choose from.[18]

For Fitbit Smartwatches, a new Exercise API and open sources tools have been added, allowing developers to build apps in a more efficient and faster way.[19]

Fitbit has also announced that Fitbit apps will offer a more comprehensive view of menstrual cycle data, which can be monitored through the Female Health Tracking trends in the apps. This new feature is expected to be rolled out in early 2019.[20]

On January 2, 2019, the company announced the release of the Fitbit Charge 3 in India. The product has been made available for all the major retailers both offline and online[21] including Reliance Digital, Croma, Helios and other major retailers.[22]


A small 2014 study of eight fit band devices during 69-minute workouts that included 13 different activities found the bands were at best “reasonably accurate”, with the Fitbit Zip and Fitbit One scoring 10.1% and 10.4% error ratings, respectively.[23]

A small 2015 study had participants wear multiple devices on their wrists and hips while performing different walking/running speeds on a treadmill. Fitbit devices worn on the hip accurately measured steps taken within 1 step of 100% accuracy. Devices worn on the wrist, however, were off by an average of 11 steps per minute. When measuring the number of calories burned, Fitbit devices worn on the hip underestimated by an average of 6%, while devices worn on the wrist overestimated calories burned by 21%. Authors concluded that both the Fitbit One and Fitbit Flex devices reliably measured step counts and energy expenditure, with hip-based Fitbit devices being more accurate than wrist-based devices.[24]


Fitbit, working with the Consumer Protection Safety Commission, recalled the Fitbit Force on February 20, 2014 because some users experienced allergic reactions to the materials used in the product.[25] On March 12, 2014, the Consumer Product Safety Commission (CPSC) made the recall official.[26] At that time, it was revealed that there were 9,900 reports of skin irritation and 250 reports of blistering.[26]

In April 2017, a woman claimed her Flex 2 malfunctioned and caught fire, causing second-degree burns on her arm.[27] Following an investigation, Fitbit was adamant the cause of the exploding tracker was due to external forces, and assured its customers that it was not aware of any other complaints and they can wear their own Fitbit without concern.[28]


Headquartered in San Francisco, California, Fitbit was founded on March 26, 2007 by James Park (CEO) and Eric Friedman (CTO). On May 7, 2015, Fitbit announced it had filed for IPO with a NYSE listing.[29] The IPO was filed for $358 million.[30] The company’s stock began trading with the symbol “FIT”[31] on June 18, 2015.[32] After Fitbit’s stocks fell more than 50% in 2016, CEO James Park announced in October that the company was undergoing a major transformation from what he called a “consumer electronics company” to a “digital healthcare company.”[33]

In February 2018, Fitbit announced that they would be partnering with Adidas to release an Adidas-branded Fitbit Ionic, which was released on March 19, 2018.[34]

In August 2018, Blue Cross Blue Shield Association announced a partnership with Fitbit where BCBS will include Fitbit’s wearables and fitness trackers in its Blue365 program.[35]


On March 5, 2015, Fitbit announced that they had acquired fitness coaching app developer Fitstar for $17.8 million.[36][37]

On March 12, 2016, Fitbit acquired smart credit card company Coin, which included key personnel and intellectual property, but excluded any of Coin’s hardware products, which stopped being produced around the time of the acquisition. Fitbit shut down the Coin Rewards and Coin Developer Program during the acquisition. Coin said that existing Coin cards will continue to work until the battery runs out and that existing Coin cards will remain under their one year manufacturer’s warranty.[38][39]

On December 6, 2016, Fitbit acquired assets from Pebble, including key personnel, as the company decided to stop producing wearable technology. The acquisition excludes Pebble’s hardware products.[40][41]

On January 10, 2017, Fitbit acquired Romania-based smartwatch startup Vector Watch SRL. Vector said that there will be no new products with the Vector name, but that existing Vector watches will continue to work.[42]

On February 13, 2018, Fitbit acquired Boston-based software startup Twine Health for an undisclosed amount. A Fitbit spokesperson said that “nearly all” of Twine Health’s employees would start working at Fitbit.[43]


Dedicated Fitbit retail stand stocked with different Fitbit Flex trackers


Fitbit has won numerous awards, including runner-up at TechCrunch50 in 2008[44] and Innovation honoree and best in the Health & Wellness category at CES 2009.[45] In 2016, Fitbit ranked 37 out of the 50 most innovative companies for that year.[46] In 2016, the company was ranked #46 on the Deloitte Fast 500 North America list.[47]

Privacy concerns[edit]

To set up and use the hardware, one has to create an account with Fitbit and agree to data collection, transfer and privacy rules.[48]

Starting in June 2011, Fitbit was criticized for its website’s default activity-sharing settings, which made users’ manually-entered physical activities available for public viewing.[49] All users had the option to make their physical activity information private, but some users were unaware that the information was public by default. One specific issue, which technology blogs made fun of, was that some users were including details about their sex lives in their daily exercise logs, and this information was, by default, publicly available.[50] Fitbit responded to criticism by making all such data private by default and requesting that search engines remove indexed user profile pages from their databases.[49]

The company’s devices have also been used in criminal investigations; in one instance, a rape claim against an unnamed intruder was turned around to a criminal charge for false reports based on data from the claimant’s Fitbit.[51][52][53][54][55]


A Fitbit device played a role in solving a murder.[56] Connie Dabate was murdered by her husband Richard Dabate. Initially, Richard framed the situation, telling police and law enforcement officials that an intruder had broken into their home and fatally shot his wife. However, Connie’s Fitbit tracker showed that she was at the gym at the time Richard told police his wife was shot. Using Connie’s Fitbit and analyzing her movements, analysts were able to create a timeline that proved Richard had created a false story.[57]

On March 10, 2015, a woman fabricated a story[58] in which an intruder appeared in her employer’s home she was staying at and raped her. Risley told police that a man had assaulted her around midnight. Police found a Fitbit lying on the floor when they arrived at the scene. Prosecutors used the Fitbit as evidence and data to determine what had occurred. The Fitbit revealed that the woman was active throughout the night, and the Fitbit surveillance analysis demonstrated the woman had not gone to bed like she stated to the police, proving that the woman had lied to the police.

A Fitbit device played a role in solving another murder in 2018. Anthony Aiello murdered his stepdaughter Karen Navarra while visiting her home and her body was found one month later. Data from her Fitbit fitness tracker showed that her heart rate spiked when Aiello visited her and stopped five minutes before he left. Aiello was arrested in September 2018 on murder charges and was booked into the Santa Clara County Jail.[59][60]

Among young adults with a BMI between 25 and less than 40, the addition of a wearable technology device to a standard behavioral intervention resulted in less weight loss over 24 months. Devices that monitor and provide feedback on physical activity may not offer an advantage over standard behavioral weight loss approaches.
