The app "Is It Dead?" suddenly went viral today. I searched for the international version called "Demumu." It has already reached third place in the tools category. The fact proves that the main reason for going viral is still demand, while innovation is secondary. -- That said, this app is indeed useful. Now that we have entered a super-aged society, it's great for my parents to use it. I hope they don't forget to check Alpha and send me a bunch of messages like I often do.🤣
