AddiGo - Mental math practice

AddiGo is a mental math trainer that helps you improve your arithmetic skills quickly and without stress at any age. It is great for students, professionals, and anyone who wants to calculate in their head faster and more confidently in everyday life. Train mental math with no distractions: a clean, minimal interface keeps you focused on problems and reaction speed. Practice all core operations: addition, subtraction, multiplication, and division — separately or in a mixed mode where tasks switch between operations. Choose your difficulty: from easy ranges like 0–10 up to “Genius” with fully random values, so you can gradually increase the challenge. Three lives per session: every mistake matters and helps you develop accuracy, focus, and discipline. Infinity Mode for maximum challenge: play until your first error, beat your high scores, and track how your best result improves over time. Perfect for learning and self‑development: use AddiGo to prepare for tests and exams or as a daily brain workout. Designed for iPhone: the UI follows familiar iOS patterns, so everything feels natural from the first launch. Minimal ads: enjoy the free version with unobtrusive ads or upgrade to a low‑cost subscription for a completely ad‑free experience. With AddiGo, every short session becomes a step toward faster, more accurate, and more confident mental math. ----- Legal Notice ----- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
