Perspective
Whoop 1.0 was released in 2015.[8] A second version arrived in 2016,[9] and a third in 2019.[10] Whoop 4.0 debuted in 2021,[11] with new battery technology that replaces graphite anodes with silicon, thus increasing battery capacity.[12][13]
In May 2025, WHOOP launched the WHOOP 5.0, featuring a 14-day battery life, 10× power efficiency, and faster data processing, alongside the WHOOP MG, which introduced a blood pressure wellness feature and an FDA-cleared ECG and Heart Screener.[14][15]
The wearable device collects data on sleep, heart rate variability, resting heart rate, and respiratory rate to create a daily recovery score for users.[16] The recovery score ranges from 0% to 100% to let users know if their body is recovered or if it needs rest.[17] It provides a suggested exertion goal based on day-to-day recovery and sleep.[18]
On March 29, 2023, Whoop announced its Stress Monitor feature, which tracks daily stress levels through heart rate variability (HRV) and measurements of resting heart rate to provide a personalized Stress Score. In partnership with Dr. Andrew Huberman, they introduced breathwork interventions designed to decrease stress or increase alertness.[19]
In September 2023, Whoop released its new "Whoop Coach" feature powered by OpenAI, which was designed to provide personalized health and fitness coaching. The feature allows members to converse with the program to ask personalized questions and have conversations about their training and health.[20]
In 2025, WHOOP shared that the FDA was "overstepping its authority" following the agency's comments on the company's blood pressure wellness feature.[21]
In May 2025 WHOOP released the WHOOP 5.0 and WHOOP MG and adjusted its upgrade terms,[22] which initially surprised some subscribers because the options were a modest upgrade fee ($49 for the 5.0, $79 for the MG)[23] or an additional 12 months on their subscription;[24] WHOOP said the confusion came from an incorrect blog post,[25][26] updated the policy on May 10 to provide complimentary 5.0 upgrades for members with 12+ months remaining,[27][28] and offered refunds to those charged in error.[29][30][31][32]
The most notable difference between Whoop and other wearables is physical: Whoop has no screen or buttons; all information must be viewed on a user's smartphone.[33] The Whoop app is available on Android and Apple devices. Other notable differences include price (Whoop charges a monthly subscription fee; without a subscription, the device stops tracking[34]) and data (according to Time, the device accumulates more data than its peers; its five sensors collect 100 megabytes of data per user, per day[35]).

History
In 2012,[36] Will Ahmed, a Harvard University student athlete, founded Whoop to help athletes gain greater visibility into their own fitness and rest.[37][38] The name "Whoop" is a phrase Ahmed used before big games in college.[36] Along with two fellow students at Harvard, John Capodilupo and Aurelian Nicolae,[39] Ahmed incubated a prototype at Harvard Innovation Labs.[40][41] The company raised $200 million from venture capital fund SoftBank in August 2021, at a valuation of $3.6 billion.[38] Other investors include IVP, the NFL Players Association, and athletes such as Kevin Durant, Patrick Mahomes, Rory McIlroy, Eli Manning, and Larry Fitzgerald.[42]
As of November 2022, Ahmed is the company's chief executive officer,[43] and Nicolae is the director of mechanical engineering.[44] Capodilupo was chief technology officer until he stepped down in April 2022.[45] Investors in the startup include institutions such as the SoftBank Group[46] and the National Football League Players Association,[47] as well as individuals such as basketball player Kevin Durant[48] and football players Patrick Mahomes and Eli Manning.[49]

In 2023, Indian cricketer Virat Kohli wore Whoop prominently during the ICC Men's Cricket World Cup. Although from old videos it shows that he has been an avid Whoop user since 2020. Kohli's use of Whoop has influenced 90% of the cricket community to invest in Whoop.[65]

Covid-19
In June 2020, PGA Tour golfer Nick Watney noticed his respiratory rate spiked on his Whoop app. Although he had no other symptoms of COVID-19, he decided to get tested, and was positive for the virus. This led to the PGA Tour to sign a deal with Whoop, making their products available to all golfers and caddies on Tour to reduce the spread of the virus.[68][6]
In December 2020, PGA Tour winner Scott Stallings noticed that his HRV, resting heart rate, and respiratory rate were not in the normal range on his app and soon tested positive for COVID-19. Stallings had been one of the first PGA Tour pros to wear the Whoop and claimed to initially use it for better sleep habits after his sinus surgery.[6]
Whoop has tested its product's ability to detect viruses such as COVID-19. In 2020, Whoop partnered with researchers from Central Queensland University to analyze changes in respiratory rate to predict the risk of COVID-19. The findings showed that the algorithm identified 80% of positive COVID-19 cases by day three of symptoms and 20% of positive COVID-19 cases were diagnosed two days prior to the onset of symptoms.[69]
