Show HN: I made 200 USD passively as a 16yo developer

Excel Tutor is my second SaaS, in the past two weeks, where I have generated over 200USD passive income alone.

Hey, I am a 16 year old developer based in Hong Kong and I've been trying to make successful SaaS's for the past 2 years. And it's only now worked. I built an MVP app called ExcelTutor.pro!
