Why'd It Move?
Tonight's biggest US stock move, as a 30-second quiz
Every night, the US stock that actually moved most becomes one question. You see the day's real 5-minute bars and pick why it moved — analyst action, sector rotation, earnings, macro. Then you find out, with the real reason and the numbers. Concepts you meet get filed into a library showing live values for that stock: RSI, VWAP, trend phase, short interest. Three minutes a night. English, Korean, Japanese. iOS and Android. Free, no account. Education only — not investment advice.

Hi Product Hunt 👋 Most "learn investing" apps teach you with made-up examples. This one uses the market that just closed. Every night Why'd It Move? takes the US stock that actually moved most that day, shows you its real 5-minute chart, and asks one question: why? Analyst action, sector rotation, earnings, macro — you pick, then you get the real answer with the numbers behind it. Whatever concept shows up in the answer gets filed into a library that displays the live value for that stock, so RSI or VWAP stops being a definition and becomes a number you have actually seen move. Three minutes a night, free, no account. English, Korean and Japanese, iOS and Android. I'd like feedback on two things: 1. Does one question a night feel like enough, or too little? 2. Is the "pick, then find out" order right, or would you rather read first? (Education only — not investment advice.)
