In December 2025, The Observer reported that Bumble relies on a legacy technology stack that was first built in 2005 due to Bumble's partnership with Badoo. The stack includes an in-house payment system and physical servers maintained by Bumble employees. Following her return as Bumble CEO, Wolfe Herd ordered a rebuild of Bumble's technology in a project known as "Bumble 2.0", in which the Bumble app would be rewritten from scratch.
Users swipe right to "like" a potential match and left to reject them. In matches between a man and a woman, the woman must initiate the conversation with their match or the matches disappear within 24 hours unless the woman has set an opening question, to which the man can respond. In a same-sex match, either person can reach out first or set an opening question. In 2024, this system was changed so that women no longer have to make the first move during matches.
Users can sort conversations, make calls, and send photo messages.
Through BFF mode, introduced in March 2016, users can match with platonic friends of the same sex, in the same way as matching for dates.

If a user is messaged after matching with a potential partner and does not respond within 24 hours, the match disappears; this requirement was implemented in April 2016 to combat ghosting. In August, 2026, the requirement was extended to 72 hours. Before the update, men were allowed unlimited time to respond to a message from women. An update was also launched for same-sex matches, with either party allowed to initiate and the other having to respond within 24 hours.
Over time, the app introduced a wider range of gender identity options for users to identify as genderqueer or transgender.
In August 2024, 61% of Bumble users were men and 37% of users were female. That month, Bumble began developing a chatbot to act as a wingman and help users with flirting.
Content moderation
Starting in October 2016, the app banned mirror selfies, obscured faces, and photos of users in underwear among others.
In August 2017, Bumble partnered with the Anti-Defamation League to remove users who display hate speech or symbols in their profiles.
In March 2018, Bumble banned photos of users posing with guns following the Parkland high school shooting.
In 2023, the Bureau of Investigative Journalism found that many content moderators working for Bumble suffered from mental health issues, including anxiety, depression, and PTSD associated with their work, with concerns about professional mental health support, productivity targets, and understaffing.
Fake profiles and photos using artificial intelligence are prohibited and may be reported. In April 2019, Bumble launched Private Detector, an image classifier that uses artificial intelligence to automatically detect and blur nude images. It allows users to decide if they want to view, block or report the unsolicited image. Bumble made the tool open source in October 2022. In February 2024, Bumble introduced Deception Detector, a machine learning model that detects fake user profiles. Of those accounts identified as spam/scam profiles, Bumble Inc.'s testing showed that Deception Detector was able to block up to 95% these accounts automatically. That March, Bumble collaborated with Phaedra Parks, Parvati Shallow and Peter Weber of the Peacock reality show The Traitors to launch the feature.
User verification
Originally, Bumble users were required to log in via Facebook when signing up. Following the Facebook–Cambridge Analytica data scandal, Bumble added an option to sign up using only a phone number. For users who sign up with Facebook, information from their account is used to build a profile with photos and basic information, including the user's college and job.
Bumble launched a photo verification tool in September 2016 to ensure that users of the app were the same people in their profile pictures. To be verified, users are asked to submit a selfie of them performing a specific pose; the picture is reviewed by a real person who ensures the user is the person in the profile pictures. Bumble was the first dating app to include photo verification in the US. In 2025, the app also included an option to become ID-verified.
Filters
In 2020, Bumble announced a temporary feature that allowed users to expand their distance filters to match with anyone in the same country. Previously, the app only allowed people to connect within a 100-mile (160 km) range. Daters could also add a "virtual dating" badge to their profile to indicate that they are willing to date over video calls.
On January 15, 2021, Bumble temporarily suspended the option to filter matches by political preference to "prevent misuse". The move came after several women allegedly used Bumble to gather information from people involved in the January 6 United States Capitol attack, and then forwarded that information to the FBI. Bumble was criticized by many of its users for being perceived to "protect terrorists" by suspending the filter. Bumble announced that it would be reinstating the option to filter by political preferences later that day.
Paid features
In August 2016, Bumble introduced paid features including Beeline, a list of users who have liked the user; Rematch, which keeps expired matches in a user's queue for 24 additional hours; and Extend, which allows users unlimited 24-hour extensions for matches.
Other features
In June 2016, the app began allowing users to connect their Spotify accounts to their Bumble profiles to show their music interests.
In 2017, the company launched a career networking app, Bumble Bizz. It also uses a woman-first interface.
In September 2018, a "snooze" feature was added to allow users to pause activity and avoid using the app for some time.
In June 2019, Bumble introduced in-app voice and video calls. Bumble's vice president of strategy reported "an 84 percent increase in video calls that were placed between users" during the COVID-19 pandemic.
Another feature allows women to share details about their dates, including: who they're meeting, and the time and location of the meeting, with a contact for safety reasons.
Security vulnerabilities
In June 2021, Stripe software engineer Robert Heaton found a security vulnerability in Bumble that allows an attacker to obtain the exact location of its users via trilateration. Bumble fixed the vulnerability three days later and paid Heaton a bug bounty of $2,000.
In August 2024, researchers at KU Leuven in Belgium found that several dating apps, including Bumble, had vulnerabilities that would allow bad actors to obtain users' locations via trilateration.
In January 2026, Bloomberg News reported that Bumble was hit by cyberattacks, along with Crunchbase and Match Group. Bumble said the intruders did not get into its member database, accounts, direct messages or profiles.
Reproductive rights
In September 2021, Bumble set up a relief fund for those affected by the Texas Heartbeat Act. In response to the decision in Dobbs v. Jackson Women's Health Organization, which overturned Roe v. Wade, Bumble made additional donations to the American Civil Liberties Union of Texas and Planned Parenthood.
Bumble led an amicus brief in both Zurawski v. State of Texas (2023) and Moyle v. United States (2024), arguing in favor of reproductive rights.
