## What is Mathy?

Train your mental math for case interviews, school, or just for the fun of getting faster.

Mathy is a fast, focused mental math trainer built for the numbers that show up when speed matters: consulting case interviews, exams, homework, business estimates, and everyday brain training.

Whether you’re preparing for consulting or finance case interviews, class, or your own personal best, Mathy helps you turn tricky calculations into reflexes. Practice big round numbers, percentages, market-share math, clean division, fraction simplification, and zero-tracking until they feel natural.

Work through drills across:
- Addition and subtraction, from warm-ups to large-scale numbers
- Multiplication with clean, practical values
- Division with answers that land cleanly
- Percentages, including percent-of-a-number, percent-of-a-percent, and reverse percentage problems
- Market-share style calculations
- Fraction simplification

Choose the practice mode that fits your moment:
- Timed Round to build speed under pressure
- Fixed Set of 10, 20, or 50 questions for deliberate practice
- Endless Mode for warm-ups, flow, or long training sessions

Set your difficulty level, or let Mathy surprise you with a random level. Keep it light, make it serious, or push yourself until your brain starts seeing patterns automatically.

After every session, Mathy shows a clean results table with your answer, the correct answer, and how long each question took. You’ll see where you’re improving, where you’re slowing down, and when you beat your personal best. Tap any question to see how Mathy would solve it: a clear, step-by-step mental-math strategy that breaks the problem into the rounding, multiplying, and adjusting a fast solver would actually do in their head. It's not just the right answer; it's the shortcuts to get there.

Mathy is fully offline, private, and built for speed. No accounts. No tracking. No data leaving your phone. Just instant feedback, zero lag between questions, and a native iOS experience that gets out of your way.

For interviews, school, or the simple satisfaction of sharper mental math: open Mathy and start drilling!
