Battle Crunch MathsFrequently asked questions
Is Battle Crunch Maths free?

How does Battle mode work?
Create a battle, share the invite code (or invite a friend), and you both solve the exact same grid in real time. First to crunch it — or with lives left — wins.

Go to Settings. For each difficulty you can pick the number range and which operations (＋ − × ÷ x² x³ √) appear.
How do I turn on Face ID / fingerprint sign-in?
Open your Profile and toggle Biometric quick-login. It's optional and handled by your device.
How do I delete my account and data?
