Euclid is a focused mental math trainer designed to build speed and confidence with numbers. No ads, no subscriptions, no data collection — just you and the math.
Choose from 10 operation types — addition, subtraction, multiplication, division, squares, square roots, exponents, percentages, fractions, and mixed operations — and toggle each one on or off to build the exact training session you want.
Pick your difficulty:
• 1–100 for warm-ups and fundamentals
• 100–1,000 for intermediate practice
• 1,000–10,000 for serious number crunching
• Adaptive mode, which starts easy and raises the bar as you improve
Play your way with two game modes: race against the clock in Timed mode, or work through a fixed set of problems in Task mode.
Track your progress over time with detailed stats — accuracy, speed, streaks, and session history — so you can see exactly where you're improving and where to focus next.
Need a boost? The built-in tips section offers practical mental math strategies to help you solve problems faster.
Euclid is a one-time purchase. Pay once, own it forever. No recurring fees, no in-app purchases, no hidden costs.
Your data stays on your device. Euclid collects absolutely nothing — no accounts, no analytics, no tracking. Your practice is yours alone.
Whether you're a student preparing for exams, a professional who wants quicker calculations, or anyone who enjoys the satisfaction of solving problems in their head — Euclid is your daily mental gym.
