Critical Thinking - Practice
Logic, biases & fact-checking
Only for iPhone

Most bad arguments are not stupid. They are convincing — that is exactly why they work.
This is a practice app, not a lecture hall. Every morning you get three questions built on a real case: a report that quietly leaves out the bad weeks, a headline that implies more than it says, an argument that almost holds. You answer, you see why the wrong options feel right, and you keep the move that defuses that trick next time.
WHAT'S INSIDE
Daily practice
Three questions a day, each with a full breakdown. Three minutes, and the reasoning stays with you.
Three courses, 66 lessons
• Critical Thinking — 21 lessons with video and notes: testing arguments and sources, spotting manipulation, making better-balanced decisions.
• Critical Thinking and Health — 21 lessons on telling evidence from persuasive stories, checking health claims and deciding without panic.
• Cognitive Biases — 24 lessons on the most common thinking traps: how each one works, where it catches you in money, work and the news, and the move that defuses it.
50 quizzes
Five topics — logic, biases, media, data and sources. Ten questions each, about five minutes.
AI analysis
Paste a news story, a claim or a situation you are stuck on. You get it taken apart: what is actually being claimed, what the facts support, where the weak points are, what is worth checking, and a balanced conclusion — plus one question to ask yourself.
Progress you can read
XP, a streak and skill bars by topic, so you can see which kind of reasoning keeps catching you out.
