In January, China's "Are You Dead?" app went viral — millions who live alone finally had a tool for one quiet anxiety: if something happened, who would know? I'm Alive Today is the American answer. One tap a day. Miss 48 hours, your emergency contact gets a text. Need help now? One tap sends an instant alert. No other check-in app has that. No wearable. No hardware. No rigid schedule. Built for independent adults, not seniors. The safety net is the product. The feeling is why people stay.
