Solo-living boom creates market for safety-check apps beyond China’s borders

• Safety-check apps prompt solo dwellers to check in, then alert a trusted contact after inactivity. China could reach 200 million single-person households by 2030 1. The EU reached 75 million single-adult households in 2024, up 16.9% since 2015, and South Korea hit 8 million, up from 5.2 million in 2015 23.
• Demumu, the rebrand of Are you dead, ranks second on Apple’s paid app chart in China. It appears on paid utility charts in the US and Singapore 1. It also shows up in Hong Kong, Australia, and Spain 1.
• Germany has 41 million households 4. Single adults are the EU’s fastest-growing household type, and nearly one-third of those age 65 or older are single adults 2. Those conditions set up room for safety-check tools in Western markets.

Developers of elderly-tech or safety platforms should prioritize markets with accelerating single-household growth

• Consumer app teams can target South Korea, which is set to reach 8.55 million single-person households by 2027 and 9.71 million by 2037 3. Build localized safety-check features for young professionals and seniors.
• B2B safety platforms can add automated check-ins to senior care services or insurance products in Germany, France, and Italy 4. The EU’s single-adult population aged 65+ grew 19.8% from 2015 to 2024 2.
• Messaging apps and smart home makers can bundle daily check-ins with communication features. Demumu plans messaging tools and elderly-friendly functions 5, which gives established platforms a template without building standalone apps.
