"Working late into the night is common, and sometimes I worry about collapsing at home with no one knowing. Demumu is like a silent guardian friend, reminding me that someone is waiting for my check-in."
Ms. Lin

"After my child went abroad, I lived alone. My son installed Demumu for me, saying I just need to tap once a day. I'm actually quite healthy, but it brings peace of mind—and my son worries less."
