Who's got the bigger market cap?

"Mom, what's a P/E ratio?"
"My daughter (10) explained to me yesterday why BMW has a lower market cap than Apple. I was speechless."
"I beat Dad three times in a row. With dividends. He was so mad 😄"
"Finally a kids' app where I don't have to swipe away a pop-up every 4 minutes. All four of us play together."

Parents: this one's the good screen-time moment.
Stock Battle is completely free. No trial month, no "Premium". We make money on printed card decks (if you want them), not on your kids.

08 · Frequent questions
What parents ask first.
What age is Stock Battle for?
Ages 9 and up. Reading helps — but we have a voice-over for younger kids or siblings who want to join in. USK 6 (PEGI equivalent).
How do you make money if the app is free?
With physical card decks and an optional "family support" tip. Never with ads, never with kids' data.
Are the stock numbers real?
Yes. The cards are based on real market data and updated quarterly. In-game the values are rounded and kid-friendly.
Can kids invest real money?
No. Stock Battle is a learning game — not a trading app. Anyone who wants to invest for real later should do it with their parents and a regulated platform.
What if my kid gets hooked?
There's a built-in parent-set daily time limit (default: 30 min). And no addictive mechanics like daily streaks, loot boxes or push pings.
Do I need internet?
Solo and Pass-and-Play work offline. For online multiplayer and card updates you'll need internet.
