What is the Setlog app trending in Hong Kong and South Korea?

As of April 15, Setlog had soared to the top of Apple’s App Store social-networking charts in South Korea and Hong Kong. Its traffic is surging, and search interest in the app has increased, according to an analysis of Naver DataLab and Google Trends.

It is currently available in Korean, Japanese and English, and the beta version for Android is scheduled to be released at the end of April.

The app was designed to be used among three friends but now supports up to 12 at a time, allowing groups of varying sizes to record their day in two-second snippets simultaneously across the different devices.

The process is automatic. Once a user joins or creates a “room” with friends, the app begins to work on a simple hourly schedule. Alarms ring every hour, prompting each person in the group to film a short, two-to-four-second video clip of whatever is in front of them at that moment.

When the day concludes, Setlog’s algorithm automatically takes all the hourly clips from everyone in the group and seamlessly stitches them together into a single, finished video presented in a split-screen format that offers a shared view of a day in each friend’s life.
