## What is iQz?

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

65 original puzzles 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.
Works completely offline. No account, no sign-up.
No ads.

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.
