Our "Age Filter" lets kids see rankings for their specific age group (e.g., "7-year-olds"). Seeing peers achieve high scores ignites their competitive spirit. You can also view "All Ages" to aim for the ultimate #1 spot. 3 Safe Environment & Premium Plan Designed with an intuitive interface, readable fonts, and fun sounds. To ensure 100% distraction-free learning, we offer an optional "Premium Plan" (one-time purchase) that completely removes all ads forever. [4 Math Modes] ◆ Addition: The crucial first step.

Yes, your nickname and age can be easily updated in Settings at any time. [Message from the Developer] The more you practice math, the faster and more accurate you become. We hope your family enjoys tracking progress and climbing the leaderboards together. Just a few minutes a day turns into massive math confidence! Download now and become the #1 "Math Master"!
