FocusMath vs Calcul Mental Challenge

Your brain is a muscle. FocusMath is its gym. 7 minutes a day. A session structured like a real workout: warm-up, main set, cool-down. No more, no less. Consistency is what makes you strong — not marathons. YOUR DAILY SESSION Every day, a 3-step session awaits: warm up with quick questions, push yourself on the daily challenge or your quest, and finish with a review card. Complete your session, keep your streak alive, and hit your goal of 5 sessions a week. A PROGRAM AT YOUR LEVEL — FROM 1ST GRADE TO UNIVERSITY A placement test personalizes your program from day one. Kids work on additions and multiplication tables; middle schoolers tackle percentages; high schoolers and adults take on powers, square roots and estimation. Difficulty adapts to your performance in real time. DAILY CHALLENGE 10 questions, identical for every player at your level. Compare yourself on the leaderboard, share your result, and challenge your friends on the same questions in one tap. QUEST MODE 200 levels of progression. Each level unlocks new cognitive games: memory, attention, speed. Your motivation always has a next goal. SMART REVIEW The app remembers your mistakes and turns them into personalized review cards. Your mistakes are your best teachers.
