LOS ANGELES TIMES - Heterosexual couples in the U.S. are now more likely to meet a romantic partner online than via any other mode of connection. And during the pandemic, online dating reached new heights. On Snack, users upload TikTok-style videos instead of photos. The company is focusing on on-the-ground promotion at college campuses and currently has the most users in California, Texas, Florida and New York. Schmooze, another dating app wooing Gen Z, is also organized around a form of digital content. Instead of people's profiles, users are greeted with a meme set against a colorful, cartoon-like backdrop, with the choice to swipe right for "like" and left for "don't like." Dating app called Iris is taking the opposite approach. Returning to the fundamentals of physical attraction, the app, which was launched in early 2020, has users train a machine-learning algorithm by swiping through three rounds of stock photos. It then recommends potential matches.
