Learn how the algorithms behind Tinger, Bumble, Hinge, and other dating apps work

Tinder revolutionized dating when it introduced swipe-based interactions

Many dating apps today allow users to "swipe right" to match with someone and "swipe left" to opt out of the match, but Tinder did it first, introducing swipe-based interactions in 2013. The idea for swipes came from the founder's desire to gamify dating—Tinder's early interface was based on a deck of cards that users could sort.

The way dating apps make money is changing

As downloads fall across the industry, dating apps are trying to stay competitive by adding paywalls to their business models. The more than $6B dating app industry is largely dominated by Match Group, the parent company of both Tinder and Hinge. This video explores how AI and human behavior are changing the industry one right swipe at a time.

The top three US dating apps by market share are Tinder, Bumble, and Hinge

While Tinder took up about 25% of US dating app market share as of 2024, Bumble wasn't far behind at 24%. Up-and-comer Hinge sat in third place with 18% of US market share.

The prototype for Tinder was created during a 2012 hackathon

By August 2012, Tinder, which was originally called Match Box, had launched on the Apple App Store. Match Group merged Tinder into its portfolio in 2017, the same year it set its sights on acquiring Hinge. Experts say that Match has not been declared a monopoly in part because monopolies are "hard to prove."

Why TikTok's algorithm is likely driven by what you linger on

While the inner workings of the engine driving the vast majority of the app's engagement remain a secret, it is understood to rely heavily on what content users spend the most time watching rather than swipe past. Experts believe the app can develop user profiles robust enough for its algorithm to consistently match engaging content to in as little as two hours.

Computer scientists first started trying to optimize dating using computers in the 1950s

Although early dating sites like Match.com weren't launched until the 1990s, the history of dating apps dates arguably back to the mid-1900s when computer scientists used IBM computers to solve matchmaking and compatibility problems.

Bumble's origin story includes a Russian billionaire, a Tinder cofounder, and a private jet

Whitney Wolfe Herd founded Bumble as a female-focused alternative to Tinder in 2014, inspired by the harassment she saw women on Tinder facing when she worked there. Instead of both parties being able to message each other first, on Bumble, women had to make the first move.

Landmark study pinpoints what makes a good relationship

Whether you’re finding a potential partner by swiping right on an app, or thumbing through stacks of biodata a la Netflix’s “Indian Matchmaking,” there may be some wisdom for you in the researchers’ findings.

Machu Picchu, sacred backdrop for your dating app pic

Anyone who’s been on Tinder or Hinge in the last decade has noticed it: the obligatory Machu Picchu selfie, almost as ubiquitous as those photos of men posing with a fresh-caught fish. How did Machu Picchu, of all places, become a dating-app cliche? This satirical essay from McSweeney’s doesn’t answer that question, but has a great time poking fun at it.

An overview of 12 fundamental types of algorithms and the uses for each

These include search algorithms to quickly process and find important information, cryptographic algorithms to secure communications, randomized algorithms—such as Monte Carlo simulations for estimating probabilities of outcomes—and greedy algorithms, which make optimal choices based on available data in a step-by-step fashion, as seen in navigation apps.

YouTube's recommendation algorithm relies on over 80 billion daily pieces of information

These signals include which videos a user has watched, searched for, and liked, as well as channel subscriptions and feedback selections, such as videos marked "not interested." Each user's viewing habits are compared with those of other users with similar habits, and this information is used to suggest additional content.

The matchmakers serving the elite of Silicon Valley

If members of the wealthy elite want to find romance, they often choose expensive match-making services rather than dating apps. These services can cost $150,000 for each match, and providers are experts in dealing with the unique social dynamics caused by being wealthy and the unusual egos such wealth can bring. This article explores this hidden cultural phenomenon.

The Elo rating system allows you to compare teams across history

Why Google Search's ranking system combines filters, signals, and machine learning layers

Rather than static rankings, dynamic tools continually shift search results in real time. These include Twiddlers, which adjust ranking positions based on document traits and search context, and FreshnessNode, which reshuffles top results to prioritize timely informational content.

57% of men who have dated online say their experiences have been positive

However, 51% of female users say that their experiences on dating apps have been negative. LGBTQ+ users are more likely to report positive experiences on dating apps than non-LGBTQ+ users.

NSF-funded research into matching algorithms improved the success of organ transplants

Investigations in game theory, including concepts focused on creating mutually beneficial partnerships—matching theory—led to the design of computer systems that efficiently matched kidney recipients and live donors, resulting in higher-quality matches. By 2019, these matching algorithms were used for multi-organ exchanges.

'Sweat dating' is a dating approach where partners specifically select by body odor

With dedicated events in major cities around the world, "sweat dating" offers people the chance to judge if a potential partner's smell is a match. Participants show up for an event, do calisthenics, wipe themselves with a cotton pad, and then place the smelly pad in a numbered jar for potential partners to sniff.

AI tools are trained on human-created data containing implicit and explicit biases

Because AI tools reflect patterns in their training data, their outputs may reinforce existing societal biases—especially racial ones—rather than offering neutral or fair ones. Adequate training is necessary to undermine these biases whenever new data is incorporated.

Watch how algorithms can be designed to train themselves and self-improve without human input, to the point where the optimized code is too complex for programmers to understand.

Personality tests use the Barnum effect, where vague flattery makes generic descriptions feel specific

A 1949 experiment by psychologist Bertram Forer showed that students rated identical, generic personality profiles as highly personalized. This is the same approach used in horoscopes, Myers-Briggs personality types, and fortune tellers. Even well-resourced tests like Myers-Briggs show poor test-retest reliability, with up to half of retakers getting different results.

Y Combinator takes its name from a computer science concept

Y Combinator, the startup accelerator, gets its name from the “Y combinator” computer science concept. Specifically, something called a “Y combinator” in computer science is a function that runs programs, just like the Y Combinator startup accelerator runs a program that helps grow startups.

Are emojis real communication? And other questions for the experts

Emojis took off around 2009, after Apple's operating system for its defining iPhone became available in Japan. By 2012, a standardized set of emojis was released, and now seven in ten users feel a message without one of the 3,664 official emojis is lacking.

Notch music therapy may filter out some tinnitus frequencies

Researchers in Germany have developed a smartphone app-based therapy for individuals with tinnitus associated with hearing loss. Some people with tinnitus can use this Notch app with their hearing aids to at least partially block sound frequencies matching their tinnitus pitch—turning down the volume of their tinnitus.

Prediction markets have faced questions about insider trading

While prediction markets encourage bettors to use their knowledge of a situation to inform their trades, these platforms have faced questions about when this borders on insider trading. For instance, traders on Kalshi can bet on who Taylor Swift's bridesmaids will be—but some worry that it would be unfair for Taylor Swift herself to earn money on that specific bet.
