iQz - IQ Training Brain Teaser

Keeping your reasoning sharp matters more, not less, in the age of AI. iQz is a focused daily workout for the kinds of thinking that stay valuable: spotting patterns, reasoning under constraints, and noticing when an argument doesn't actually follow. WHAT'S INSIDE - 100 original puzzles, free, across five reasoning types: - Abstract reasoning - 3x3 matrix puzzles, the classic IQ-test format - Spatial reasoning - rotation and sequence completion - Numerical reasoning - number series and quantitative problems - Verbal reasoning - analogies, odd-one-out, word relationships - Logical reasoning - syllogisms, deduction, and common reasoning fallacies - Every answer explained. Not just which option is right, but the underlying rule - so you get better instead of just scoring. - Optional pace timer: a non-enforced ~2 min/question countdown, roughly the pace of a timed reasoning test. It never locks you out or auto-submits. - Progress tracking: streaks, best scores and full history, stored on your device. - No account, no sign-up. No ads. 100 MORE, RIGHT IN THE APP Played them all? One in-app purchase adds 100 more puzzles, 15 of them hard, for 200 in all. They unlock in this app, so your streak and history stay where they are. One payment, no subscription. Restore it on any device signed in to the same Apple Account. A HARD TIER 36 of the free puzzles are genuinely difficult, and difficult in a different way rather than just busier. The easier items are progressions - something advances along a row and you continue it. The hard ones are relational: the missing cell is a function of the other cells around it, so there is no direction of travel to spot. Counts that add or subtract across a row, symbols that cancel when both cells carry them, cube nets you have to fold in your head, and grids running three independent rules at once. There is a Hard Only mode, so you can go straight at the ceiling instead of waiting for a hard item to come up. They were added because someone told us the puzzles were too easy. They were right. BUILT FOR FLIGHTS Every puzzle ships inside the app, so airplane mode, the subway and a dead-zone basement behave exactly the same as full signal. Only the News tab and buying the extra puzzles need a connection. EVERY PUZZLE IS ORIGINAL The visual puzzles are generated specifically for this app, each built from a defined rule so the stated answer is provably the correct one. Nothing here is scraped from another test. Every hard item is additionally machine-checked to confirm that exactly one of the six options satisfies its rule - an ambiguous puzzle is worse than an easy one.
