Why'd It Move?
Tonight's biggest US stock move, as a 30-second quiz
What it does
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.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
