In November 2016, Tinder introduced more options for users to select their gender.
In the app's settings, users have the option to type a word that suits their gender identity.
Rad and Mateen had known each other since they were 14.
They later attended USC together and entered the Internet entrepreneurship field.
Analysts also estimated that Tinder had about half a million paid users within its userbase that consisted mostly of free users.
The New York Times wrote that the wide use of Tinder could be attributed not to what Tinder was doing right but to flaws in the models of earlier dating software, which relied on mathematical algorithms to select potential partners.
The average user would generally spend about an hour and a half on the app each day.
The selections a user makes are not known to other users, unless two individuals swipe right on each other's profiles.
However, once you have matches on the app, you were able to send "Tinder Moments" to each of a user's matches at once, allowing each match to like or not like the photos.
Rad has stated that the impetus for the app was his observation that "no matter who you are, you feel more comfortable approaching somebody if you know they want you to approach them." He believed that a "double opt-in" system could be created to potentially alleviate that stress.
Rad has also stated that Tinder filled a gap for social sites for meeting strangers, rather than connecting with people a user already knows.
