It’s not every day that we see an app blow up because of a social media trend. However, it looks like Zenly is experiencing a spike in popularity thanks to a growing trend on TikTok. The app has seen a 121% growth in active users since the trend gained popularity.

Zenly is an app that allows you to track other people. The app began to see a spike when the trend of showing screen recordings of your loved ones moving on the map in real-time started to gain popularity. The screen recording is accompanied by the song “Segala” by Mohd Mentor. According to Zenly, the trend helped highlight one of the app’s key features which is to allow users to “look out for loved ones and know what they are up to and ensure they are safe”. In fact, the team at Zenly confirmed that the app is frequently used by couples. Some other demographics using the app include best friends, siblings, roommates, and colleagues.

If you recognise the app’s interface, don’t be too surprised. Zenly is part of the Snap Inc family so you probably recognise the interface from the Snapchat app. The app is popular in countries like Japan, Russia, Indonesia and France.
