Mental arithmetic is a muscle: a two-minute drill a day does more than an hour once a month. Tune the difficulty to exactly the right level — times tables 2–12 for school practice, three-digit sums for adults — and let the instant feedback do the teaching. Wrong answers are collected for review at the end, your best score for each setup is remembered on this device, and you can copy or download any round's results. No account, no ads, works offline.
