FAQ: Prediction Market Apps for iPhone

Are prediction market apps free to download?

Yes. All major prediction market apps are free to download. Real-money trading requires deposits, but the apps themselves are free.

Why are some prediction market apps not on the App Store?

Apple's App Store policies restrict certain types of real-money trading apps. Some platforms operate as progressive web apps (PWAs) to bypass these restrictions while still providing a good mobile experience.

Which app is best for beginners?

Manifold Markets is the best starting point because it is free, easy to use, and has no financial risk. Once comfortable, move to Kalshi (US) or explore other real-money options.

Can I trade on my Apple Watch?

Currently, no prediction market app offers a full Apple Watch app. Some apps provide basic notifications on Apple Watch, but trading requires your iPhone.

Do prediction market apps use a lot of data or battery?

No. Prediction market apps are lightweight compared to social media or streaming apps. Real-time price updates use minimal data, and battery usage is comparable to a news app.

The best prediction market app for your iPhone depends on your goals. For US-based real-money trading, Kalshi is the clear winner. For the widest market selection, Polymarket's mobile experience is unmatched. For free learning and experimentation, Manifold is perfect.
