Twelve reasoning and math types generated from rules, so you never run out. Everyone solves the same Daily Challenge, and Survival takes you one floor at a time. ``` ### iOS β Description (4000) Β· Play β Full description ``` Matrix Aptitude drills the reasoning and numerical question types that keep showing up in aptitude tests, a little every day. Questions are built from rules, so they never run out no matter how many you solve. It runs offline with no server. β Twelve rule-generated types Matrix, Sequences, Odd One Out, Applied Math, Data, Verbal Logic, Spatial, Analytic, Ciphers, Flow, Analogies, and Schematic. The names of the tests differ, but these types keep coming back. Generated fresh from rules, so they are unlimited. Get them right and they get harder; miss and they ease off. β Daily Challenge The same ten questions worldwide, once a day. The date picks the questions, so today's set is identical on every device. Share your result as a grid. β Survival Three lives, one floor at a time. Every floor is harder, and it ends when your lives run out. How far you climbed stays on your record. β Fifteen questions a day A daily set of fifteen β warm-up, weak-spot focus, then a challenge. Streaks build, your think level rises, and milestones stay for good. β Timed mock A 50-question mock with a clock and a penalty for wrong answers, so you can practice leaving the ones you are unsure of. Afterwards you get score by part, points lost to guessing, how you spent your time, and one thing to change next time. β Diagnose β Prescribe β Grow A short placement sets your baseline. Then the app shows which types are weak, how you miss them, and exactly which sub-pattern trips you up. Drill just that sub-pattern or learn the method with a strategy lesson, and measure your gains against your baseline. β A buddy that grows with you Name your own training buddy. It feeds on your daily training and evolves through 10 stages, and milestones like a 7-day streak become relics that never disappear. β What it covers What practice improves is familiarity with question types and how you handle a clock. Reading comprehension and paragraph ordering need passages, so they cannot be generated from rules and are not covered. β How it works Everything is open. Nothing is locked and there are no run limits. A banner ad sits at the bottom of result screens, and Survival offers a rewarded video if you choose to continue. Question screens carry no ads. β Features - Korean / English toggle - Dark mode (system / light / dark) - Daily reminder - Share your score card as an image - Works offline (rule-based, no network needed)
