Timed math facts vs Pinyin Reader

QuickMath is math fact practice that pays attention. Every answer you give is remembered. Get 7 x 8 wrong twice and it comes back until it sticks — while the facts you already know stay out of your way. That is the whole idea: practice time spent on the gaps, not on what you can already do. Choose addition, subtraction, multiplication, division, or mix them. Pick a number range from starter to advanced. Answer by tapping or by typing on the built-in number pad, with an optional timer per question or for the whole session. At the end you get more than a score: every missed question, the correct answer, and one tap to drill just those facts again. Track a daily streak, watch your accuracy per operation, and see exactly which facts still need work. No account. No ads. No analytics. Nothing leaves your device.
