NightFail

Ao Bai is a fun, lighthearted app that helps you track your late nights, see the real cost of staying up late, and gradually build a habit of going to bed earlier. It’s not about professional medical monitoring. Instead, it solves a real problem: you know staying up late is bad for you, but you just lack feedback, motivation, and a little fun company along the way. Tone: Self-mocking but not defeated; fun but not cheesy; health-conscious but not preachy. Like a friend teasing you—not a doctor lecturing you.
