Description
Can you still calculate a tip, split a bill, or work out a percentage in your head?

Every time you reach for a calculator or ask AI, your mental math skills quietly fade. The good news: they come back fast with regular practice.

NumDrill is a focused mental math drill app designed for short, satisfying sessions. Instead of mindless scrolling or another mobile game, sharpen the brain you already have.

■ Who it's for
· Anyone whose mental math has gotten rusty from over-relying on calculators or AI
· Students preparing for exams or standardized tests

· Anyone who suspects they're wasting time on games but keeps playing anyway

■ 9 Problem Categories
- Arithmetic (addition, subtraction, multiplication, division — customize digits & decimals)
- Quadratic expressions (factoring & expansion)
- Trigonometry (sin / cos / tan values)
- Square roots
- Logarithms & Exponents
- Ratio & Percentage (everyday percentage calculations)
- Make10 / Make24 (card-based number puzzles)
- Memory (memorize and recall grids of numbers & icons)
- Calculator mode (Practice mental arithmetic using calculation patterns you frequently use in everyday life)

■ 4 Play Modes
- Count / Timed / Sudden Death / Endless

■ Features that keep you coming back
