About this app

How sharp is your mind today?
MentalMather measures your daily cognitive performance through mental math — not by comparing you to others, but by tracking how you perform against your own personal baseline.
Your Sharpness Score is a percentage showing whether you're above or below your normal. Think of it like a wellness check for your brain.
How It Works
Open the app, take a quick test, and get your score. MentalMather builds a personalized baseline from your history across addition, subtraction, multiplication, and division, then measures each new session against it. The result is a clear, honest snapshot of how your mind is performing right now.
What You Get
Your Sharpness Score is a personalized daily cognitive performance metric that adapts to you. Choose from four difficulty levels (Easy, Medium, Hard, and Expert) across four operations. Dive into detailed stats including lifetime performance, per-operation breakdowns, personal bests, and full session history. Track your trend over days and weeks with the sharpness graph. Challenge friends with async matches — share codes, set time handicaps, and compare results. The app features a clean, premium design with both light and dark themes.
Who It's For
MentalMather is for people who want to monitor their cognitive sharpness the same way they track steps or sleep — a daily brain check for competitive, performance-minded adults.
