Spend enough time on the social media app TikTok, and you’re bound to see a Life360 meme. That’s because Life360, a location-sharing app aimed at families, is apparently ruining the lives of teenagers all across the United States. The service allows parents to track their kids’ whereabouts in real time, among other features. As one girl with long, blond hair jokes in a popular TikTok clip, it’s set her summer vacation on fire. Some of the videos have racked up hundreds of thousands of likes—in other words, they’re relatable.

That’s because for many adolescents, adult supervision has turned into adult surveillance. Schools are adopting facial recognition technology to monitor campuses. Parents can now remotely check their child’s browsing histories and social media accounts, watch their movements via motion-sensing cameras, and track everywhere they go with location-sharing apps. In a Pew Research Center study last year, 58 percent of US parents said they sometimes or often look at their teenager’s messages, call logs, and the websites they visit. In a separate study from 2016, 16 percent said they used location-sharing apps.

Life360 is one of the many digital monitoring tools now used by millions of parents in the United States. The app functions like an enhanced version of Apple’s “Find My” feature that lets you share your location with friends or family—or what the company calls “your Circle.” In addition to location sharing, Life360 lets family members see how fast people in their circle are driving, how much battery their cell phones have, and more. The service is free to download and use, although you can pay for additional features. According to the San Francisco-based company, Life360 had over 18 million monthly active users at the end of 2018.

Apps like Life360 can give kids and parents a sense of security, but they also raise questions about privacy and children’s autonomy. And on TikTok, teenagers are discussing and debating them. Videos with the hashtag #Life360 have been viewed there over 13 million times. In some of the most popular clips, teens share with each other strategies for circumventing the app, usually by turning off various phone settings. Other videos are less practical and serve more as a form of venting. In one recording with more than 30,000 likes, a photo of Life360’s founder and CEO Chris Hulls appears onscreen, while a rap song with the lyrics “Snitch, snitch, the snitch, the snitch, snitch” plays.

“I think it’s completely unfair and detrimental to teenagers if their parents use this app on them regularly,” said a 16-year-old boy from Texas who, like all the young people in this story, was contacted via social media and requested anonymity to talk freely about his family. “I spend most of my time texting my parents about what’s going on rather than spending time with my friends.”

Other teens are more understanding of their parents’ use of the app but think Life360 is too invasive. “If I am going a little over the speed limit on the freeway just to keep up with traffic, my parents freak out,” said a 16-year-old girl from California. “I understand where my parents are coming from, but I believe that the app has too many features that make it over the top.”

Life360 COO David Rice argues that these teenagers represent a vocal minority. “Teens who take issue with Life360 are often the loudest, but in reality a vast majority of teens are OK with location sharing,” he said in an email. The practice has “become the new norm for today's digitally native families.”
