3 apps with 3 different philosophies around personal safety
Last week, while scrolling through tech news, I came across something that made me pause: a Chinese app called Demumu (literally « Are You Dead? ») had just become the #1 paid app in China and was climbing charts in the US. The concept? Users tap a button daily to confirm they’re alive. Miss two days in a row, and an emergency contact gets notified.
As someone who built Tribe Check, a safety check-in app, this news hit close to home. But it also made me realize something important: there isn’t just one way to approach personal safety. Different apps use fundamentally different philosophies to keep people safe. And understanding these differences matters, because the right safety app depends entirely on your specific needs and situation.
Demumu vs Tribe Check: Two Different Approaches to Solo Living Safety
Early January 2026, a Chinese app called « 死了么 » (literally « Are You Dead? ») shot to #1 on the App Store. The premise was simple: check in every 48 hours, or your emergency contact gets an email. The app, now rebranded as « Demumu, » went viral with millions of downloads.
Here’s what’s interesting: I built Tribe Check six months earlier, targeting the exact same problem. Same fear. Same market. Completely different approach.
My challenges as an independent app-maker
A couple of years ago I started to learn to code with Flutter and dart in order to code my own mobile application, Tribe Check. In addition to learning the technology, and before my product was available to all on the stores, I encountered many challenges, technical, of course, but also administrative. Here is an overview of my main challenges as an independent app-maker, starting as a digital designer!
Tribe Check at Geneva Digital Health Day 2025
I will be presenting my mobile app, Tribe Check, at the Geneva Digital Health Day 2025 on May 22nd.
In just 5 minutes, I’ll pitch how Tribe Check provides a safety net for vulnerable individuals—and how it can support doctors, nurses, and healthcare professionals in following up with at-risk patients. The goal: making sure that if something happens, someone knows and takes action.
From UX to app-making: a self-taught journey
After about 20 years as a UX Designer, I started feeling this eager to actually make something. Not a mock-up or a wireframe. The real product. 3 years later, my first app is live on the Play and App stores, I am working on a PRO version and starting my first ever PR campaign to promote it and reach my users. From learning to code with Flutter and dart to how ChatGPT and Copilot helped me through that journey, here is a summary of how it went.
