Math IQ: Fast mental Math

Math IQ turns mental-math practice into a game you'll want to come back to every day.

Challenge yourself across 10 difficulty levels, or focus on a single operation — addition, subtraction, multiplication or division. Track your solving time, build streaks, and break your own records.

WAYS TO PLAY
• Practice by level or by a single operation (+ − × ÷)
• Today's Challenge — a fresh daily set, matched to your level
• Adaptive Quiz — difficulty adjusts to how you're doing
• Word Problems — math in everyday situations
• Times Tables — drill one table (2 to 12) or all of them
• Sprint — answer as many as you can in 30, 60 or 120 seconds
• Advanced Practice — percentages, squares and square roots
• Head to Head — two players, one phone, pass and play (no quota, no score kept)
• Visual Fractions — learn fractions with interactive pie charts

LEARN FROM MISTAKES
• Missed Box collects every question you got wrong and brings it back at spaced intervals until you master it
• Every wrong answer comes with a short worked explanation
• A Missed Box widget on your home screen reminds you what to revisit

PROGRESS THAT MOTIVATES
• Rank & XP — climb from Bronze upward as your skills grow
• Achievements, personal leaderboard & detailed statistics
• A daily streak and an optional daily reminder
• Up to 6 player profiles on one device, each with its own scores, history and badges — great for siblings or a classroom
• Export your history to CSV
• Home-screen widgets: best level, streak, 7-day trend, today's challenge and Missed Box
• Fully offline — practise anywhere, anytime (watching an ad for a bonus quiz needs a connection)

Perfect for students sharpening arithmetic, adults keeping their minds fast, and anyone who enjoys a quick brain workout.

FREE & PLUS
Math IQ is free to use. Free players get 3 scored quizzes a day, and can watch an ad for one extra quiz (up to 2 a day). Visual Fractions, Head to Head and Missed Box review are always free and unlimited, and Today's Challenge is free once each day, so your daily streak never depends on the quota. Plus removes the daily limit entirely.

PLUS (optional)
Plus is a monthly or yearly subscription; cancel any time in Google Play. It unlocks unlimited quizzes and Detailed Insights — your strongest and weakest levels and average solving time — plus an ad-free experience and exclusive themes. Paid features are clearly marked with a Plus badge before you tap.

No account required. Your progress stays on your device.

Please note: "IQ" is part of the app name. Math IQ is a practice game, not a clinical or standardised IQ test, and its scores are not a measure of intelligence.
