Good questions
Before you
jump in.
Do I need investing experience?
No. The Beginner track introduces ownership, saving, inflation, and the market. If you already know the basics, explore the more demanding ideas in the other tracks.
Is this a trading app?
Learn Stock Market is focused on education. The lesson examples explain how investments work and where their risks come from. They are not personal investment recommendations.
Is it available on Android?

Is the app free?
It is free to download, with in-app purchases available. The App Store and the app show the current options and prices for your region.
