Pensum vs Mental Math

Pensum is a training game for adults. Five tasks a day, about ten minutes, mixed from mental arithmetic, logic, memory and pattern recognition. The tasks get harder as you do — each category on its own, across ten levels. THE TASKS Mental arithmetic — four operations, two to three digits Missing operator — 8 ? 4 = 32, find the sign that fits Target number — combine five tiles to hit a target Number series — spot and continue sequences Propositional logic — true, false, cannot be decided Word logic — analogies and categories Remember numbers — sequences of four to twelve digits Patterns & shapes — the figure that breaks the set Pattern sequence — the rhythm continues, what comes next Matrix building — assemble the missing cell of a 3×3 pattern yourself Hatch picture — a mini nonogram that resolves into an image Reaction series — respond in fractions of a second, sustained attention HOW IT WORKS A short placement test to begin, then one round a day. The index shows where you stand; it starts at 100 and moves with your performance. Wrong answers are explained, with the method rather than a consolation prize. One reminder a day, at the time you set. A missed day does not break the streak — two do. No leaderboards, no badges, no confetti. YOUR DATA Pensum has no server, no account and no analytics. Results, levels and settings stay on the device. There are no ads, no trackers and no crash reporting. The app is entirely free. No feature sits behind a wall. If you like it you can leave a one-off coffee tip — it unlocks nothing. NOTE Pensum is a training game, not a medical device. It makes no diagnosis and does not replace medical assessment. The index is a game value, not a finding.

Mental arithmetic that feels like a game. An exercise sits on a chip in the middle — 7 + 5, 9 × 8 + 4, √144. Drag it onto the right answer on the board before the clock runs out. Land it and your combo grows, taking the multiplier up to ×3. Miss and you only lose the combo: nothing here breaks. HOW IT PLAYS • 14 seconds per exercise, shown by the ring around the chip: green, then amber, then red • Answer early and score more — the bonus follows those exact colours • Three correct answers in a row lift the multiplier one step • Eight exercises per chapter, up to three stars — fewer misses, more stars • No exercise repeats inside a run TWELVE CHAPTERS 1. Adding to 20 2. Adding to 50 3. Missing addends 4. Subtraction 5. Missing subtrahends 6. Times tables 7. Division 8. Square numbers 9. Square roots 10. Big numbers 11. Order of operations 12. Everything mixed FOR PARENTS • No ads, no purchases, no accounts, no sign-up • No cross-app tracking, no advertising ID — only anonymous statistics and crash reports, so we can find bugs • Works fully offline — the app needs no internet and asks for no permissions • Progress stays on the device and never leaves it Made for primary and lower secondary school, for anyone getting their mental arithmetic back up to speed — and everyone in between.
