Viral Girigo app craze leaves some users shaken

When Netflix released the Korean horror series If Wishes Could Kill on April 24, it came with a fictional premise designed to unsettle: an app called Girigo grants any wish you speak into your phone's camera, then gives you 24 hours to pass the curse on or die.

Within days, a real version of the app had appeared on Google Play. Within weeks, it had become one of social media's stranger viral phenomena.

What is Girigo app and how does it work?

The downloadable Girigo app markets itself as a wish-recording journal, a video tool where users speak a wish aloud, watch it back days later, and reflect on how things have changed. It is, by its own description, benign.

But its designers leaned hard into the show's horror aesthetic: the interface features pixel-art praying hands, atmospheric countdown imagery, a rule that the app canonically "only answers between midnight and 4am", and a playback feature described as returning your wish "in another voice".

A counter on the app's landing page claims over 7,341 wishes have been whispered into it, with 218 "echoes returned".

The app's eerie design has done most of the marketing for it. Across TikTok and Instagram, users are posting staged "final hours" countdowns, faux warning videos, and dramatic skits recreating the show's premise. Few are using it as a journaling tool. Most are using it as a prop, a way to perform fear for an audience already primed by the series.

The trend mirrors the show's own logic: in If Wishes Could Kill, characters interact with the app knowingly despite understanding the consequences, which is precisely what fans are now imitating in their content.

Not all users are finding the experience cleanly fictional. Several social media posts report an experience that goes beyond atmospheric design. One user wrote that after their wish "completed", the app refused to uninstall, and their phone continued playing sounds associated with it even when the app was closed.

In the series, Girigo began as a student project before being corrupted through acts of grief and vengeance by its creators, Hye-ryung and Si-won. The curse is powered by negative human emotion, a detail that resonates with why the real app's community reviews, which include users reporting fulfilled wishes, are circulating as content in their own right.
