There's an App Called 'Are You Dead?'

There's an App Called 'Are You Dead?' And I Have Concerns

I recently found out there's an app whose entire job is to email someone if I forget to tap a button confirming I'm alive. It's called, with zero subtlety, "Are You Dead?" It's since rebranded to the slightly gentler "Demumu," presumably after someone in a boardroom pointed out the name might not test well with the emergency-contact demographic.

What's actually going on

Three young developers in China built the thing for around £165 — genuinely a shoestring project. The concept: you check in daily or fortnightly with a single tap. Miss the window, and it fires off an automatic email to two people you've nominated, letting them know something might be wrong.

It went viral almost immediately and became the most downloaded paid app in China. Somebody holding a 10% stake in the company watched its value jump from roughly £110,000 to over £1.1 million in three days — which puts the whole company's valuation somewhere around £14 million, off the back of what is, functionally, a very fancy "are you okay?" text. By January 2026 it had rebranded and expanded into more than 40 countries, including the UK and the US, and it's been climbing app store charts here too.

The reason it's resonating isn't really about the app itself, though — it's about what's happening underneath it. China now has over 125 million one-person households, roughly one in four homes. There have been a number of well-documented, genuinely sad cases of people living alone dying and not being discovered for weeks or even months, particularly in dense urban apartment blocks where neighbours barely know each other's names. Demumu exists to plug that specific, unglamorous gap.

My actual take

I think this is one of those stories that's funny and slightly unsettling in equal measure, and I don't think you should have to pick one reaction over the other.

On one hand — genuinely useful. If you live alone, and a huge number of us do by choice, an automated safety net that costs almost nothing and asks almost nothing of you is hard to argue with. I'm not precious about it. If something like this existed in a form I trusted, I'd probably use it.

On the other hand, there's something worth sitting with here: we've reached a point where checking whether someone's still alive has had to become a product, because the informal version — a friend ringing, a neighbour popping round, a family member who'd notice — isn't reliably there anymore for a growing number of people. The app isn't the problem. It's a symptom, and a pretty efficient one, of something bigger about how disconnected modern solo life can quietly become if you're not careful about it.

I also can't get past the branding. Calling it "Are You Dead?" instead of something softer is, weirdly, refreshing. Nobody's dressing solo living up in twee language here — it's blunt, almost darkly funny, and it went viral because it was blunt, not despite it.

Takeaway

I haven't downloaded it. But writing this did make me seriously wonder whether my downstairs neighbour would notice something was wrong before my houseplants did. Make of that what you will.

Let me know if you'd actually use something like this — or if, like me, you find the whole premise both sensible and slightly horrifying.
