The segment examines the surge of a Chinese‑origin mobile app originally called “Are You Dead?”—now rebranded as Dimumu—that aims to combat the growing loneliness epidemic. Users tap a daily green button to signal they are alive; missing two consecutive check‑ins triggers an automatic alert to a pre‑selected emergency contact. Psychologists note the app can provide reassurance for people living alone but warn it may create a sense of obligation or over‑reliance on technology. Cybersecurity expert Robert Siciliano raises alarms about the extensive personal data shared with a Chinese‑based service, highlighting potential U.S. government and individual privacy risks. The app topped China’s Apple Store charts, now includes a subscription fee, and analysts predict it could gain traction in the United States despite the privacy concerns.

Experts say loneliness is more widespread now than it ever was.
I know a lot of people get lonely, especially in the winter here in New York. It's cold. Maybe just don't feel like people are hearing me.
But if you ever wanted to combat the loneliness epidemic and check in on yourself, well, there's an app for that. A now viral app titled Are You Dead? I think the community is the most important part. So digital community works for some, but not for everybody. The Chinese-based app, as morbid as it sounds, is resonating and surging in the world's second most populous country. Last weekend, in fact, it was the number one downloaded app in the Apple Store in China. So how does it work? Well, it's simple. You download the app and you tap to check in once a day, that big green button, so you let the app know that you're still alive. But if you go two consecutive days without checking in, Are You Dead will think you're dead and it'll reach out to your emergency contact. The best way to combat loneliness depends on who you ask.
For people that are living alone or for those that are feeling lonely, what starts to become important is that social connection, that social contact with other people.
Psychologists see a positive to the app but also say there could be a downside when relying on high tech.
For some people, it might feel reassuring to know that, um, there's someone there and that there's someone who will reach out to them if, if they're not heard from. For several days. There's another flip side of it, which is, does this set up an obligation?
Then there's the question over cybersecurity. Experts in that field say the concern is over your personal data that you share with the app.
Giving up that level of information to the Chinese is concerning at the U.S. government level, and it should be concerning, um, on the— on a private or personal level.
Since it's gone viral, Are You Dead has rebranded itself to drop that title and go by Dimumu. Which has the same meaning. There's also a subscription fee now, but with growing isolationism and loneliness across the globe, experts are sure that the app will surge here in the U.S.
Until then, stay in touch.
