Living alone has become somewhat of a mainstream choice in the 21st century. Some of us do it intentionally, others do it out of necessity.

Whatever the circumstances that lead people to living solo, it’s pretty clear that there’s a growing need for them to be able to stay in touch with loved ones, in case the worst happens and no one’s there to notice.

Well, now there’s a Chinese-developed app for that, and it’s called Sileme (which literally translates to “Are You Dead?”). Everywhere else across the globe, the app goes by the name Demumu.

It does one basic job

Designed for people who live alone, the Sileme app does its one job very well. Users just need to tap a button once a day to signal they’re fine. If they don’t check in for a few consecutive days, the app will automatically alert a pre-selected emergency contact.

Essentially, the check-in tap acts as a digital nudge, without forcing the user to post something on social media or send somebody a text just to show they’re still alive and well. You could argue that sending a text to someone isn’t hard to begin with, but a tap is arguably much quicker and easier.

Sileme’s creators call the app “a lightweight safety tool created for solo dwellers”, whether they’re students, office workers, or “anyone choosing a solitary lifestyle”. It’s pretty relevant, especially to the population of China, which now has up to 200 million one-person households.

The app doesn’t aim to combat loneliness. Instead, its main goal is to get rid of the fear of being unseen when something goes terribly wrong, like if a “solo dweller” just upped and died at home, alone.

And it seems the app has resonated with a lot of people. It’s now the second most popular paid app on Apple’s App Store, with some dupes trailing behind.

“Thanks to all netizens for their enthusiastic support. We were originally just an unknown small team, co-founded and operated independently by three born after 1995,” Sileme said, adding that they’ll be implementing an 8-Yuan (~RM4.70) payment scheme to keep the app running.

For the global audience, the app has been rebranded to Demumu, with the Chinese-market Sileme app following suit in its next update. So far, the app isn’t available on the Google Play Store (sorry, Android users).
