An indie app with only one function is currently all the rage in China. Guo, one of the three Gen-Z developers behind Are You Dead Yet, says he has been building social and entertainment apps for a few years. At the time of publication, Are You Dead Yet was the number one paid app in the Chinese version of Apple’s App Store. It is also climbing the rankings in overseas app store charts, even though Guo says he hasn’t spent a dime on paid advertising. On Weibo, a Chinese social platform, the most liked comment under the name-change announcement reads, “Baby, your previous name was the reason you went viral.”
