MentalMather measures your daily cognitive performance through mental math — not to teach you math, but to measure how sharp your brain is right now. HOW IT WORKS Take a quick Sharpness Test each day. The app compares your speed across addition, subtraction, multiplication, and division against your own historical baseline. The result is your Sharpness Score — a personalized metric that tells you whether you're performing above or below your norm. This isn't about getting better at math. It's about measuring your cognitive throughput. When your working memory is firing on all cylinders, you solve problems faster. When it's not — due to poor sleep, stress, or fatigue — your score reflects that.

MentalMather is a measurement tool. Your Sharpness Score compares you against yourself — not against strangers on a leaderboard. The question isn't "are you good at math?" It's "how sharp are you today compared to your own baseline?" Built for people who care about their cognitive performance and want a quick, honest daily check-in.
