Type two things. Watch them fight. See who wins.
Open the Battles tab. Pick Classic matchups to choose two fighters and set the numbers, or Build a custom battle to set each side's name, emoji, count and combat role. Then watch the battle play out — the winner emerges from a real simulation, not a script.
Who Would Win Pro is a one-time purchase (no subscription) that unlocks the on-device AI modes — where you type any two things and the AI gives a reasoned, fact-based verdict, then fights it out — and epic battles of up to 300 units per side.
The AI runs entirely on your device. It works offline, needs no account, and nothing you type is ever uploaded. Optionally, you can download a local AI model over the internet once; after that it runs on-device.
Make sure you're signed in with the same Apple ID you purchased with, then open the app and use Restore Purchase on the upgrade screen. Purchases restore automatically on your other devices using the same Apple ID.
