Reasonal is a critical thinking app that teaches logic, data analysis, and decision-making through short interactive lessons based on award-winning research. Learn to spot manipulation in news and media, recognize bias in yourself and others, and evaluate arguments properly. WHO IT'S FOR Built for professionals, students, and anyone who's tired of clickbait headlines, disinformation, manipulation, and questionable "studies" shared on social media. If you've ever caught yourself wasting time on something you later realized was nonsense, this is for you. WHAT YOU'LL LEARN - Critical Thinking: Analyze information faster, recognize logical fallacies, and spot biases to make better decisions and win more arguments. - Media Literacy: Identify misinformation, disinformation, and manipulative tactics before they work on you. - Decision Making: Understand how cognitive biases, sunk costs, and framing effects distort your choices, and learn frameworks to make clearer decisions under uncertainty. - Data Literacy: Interpret studies, statistics, and expert claims without getting fooled by bad methodology or cherry-picked data. HOW IT WORKS - Pick a topic: Critical thinking, logic, cognitive biases, data analysis, decision-making, economics, or media literacy. - Learn from real examples: Each lesson uses real-life examples, case studies, and award-winning research, not hypothetical textbook scenarios. - Follow your own path: The app adapts based on your responses. If you already understand something, it moves forward. If you have questions, it addresses them directly. WHAT MAKES IT DIFFERENT - Human-written and research-backed: Every lesson is researched and written by hand, citing real studies with named researchers and verifiable data. No AI generation, no hallucinations, no recycled summaries. - Branching narratives: The lesson path changes based on your choices and understanding. You're not reading the same content as everyone else. - Not a brain training game or a book summary app: Reasonal teaches transferable reasoning skills through real research, not pattern-matching puzzles or 15-minute book recaps. FAQ - What is it? An app that teaches critical thinking and logic through research-backed, interactive lessons that adapt to what you already know. Think Duolingo, but for critical thinking and reasoning skills. - Is there an app that teaches logical fallacies and cognitive biases? That's exactly what Reasonal covers. Lessons walk you through real examples of fallacies and biases using published research, then test whether you can spot them in realistic scenarios. - How fast will I see results? Most users notice improved reasoning within the first week of daily lessons. Specific gains depend on which topics you start with. - Is this AI-generated content? No. Every lesson is researched and written by hand using reputable sources and real-world examples. - How is this different from other learning apps? Branching narratives that adapt to you. Real research with named studies, not hypothetical textbook examples. Focus on skills you'll use every day, not abstract theory. COURSES - Critical Thinking - Understanding Data - Decision Making - Media Literacy - Everyday Economics ...and more coming soon. GET STARTED Start your first lesson and begin evaluating information more effectively: improve critical thinking skills and logical reasoning, spot fake news and misinformation, understand cognitive biases and logical fallacies, analyze data effectively.

Do you trust your own thinking? Most people unknowingly fall for the same logical fallacies and cognitive biases every day — in conversations, on social media, in the news, and in their own decisions. Fallacy is the first brain training app built to sharpen one critical skill: your ability to think clearly, spot flawed reasoning, and win any argument with logic. PEOPLE YOU MEET — OUTSMART REAL-LIFE CHARACTERS Ever tried reasoning with a WhatsApp Uncle who forwards conspiracy theories? Or an overconfident AI that sounds smart but gets everything wrong? In People You Meet, you go head-to-head with characters inspired by people in your life. Spot their logical fallacies, identify their cognitive biases, plan your comeback, and win arguments using critical thinking instead of volume. Every character uses different reasoning tricks — this brain training mode teaches you more about logic and flawed thinking than any textbook. MASTER 30+ LOGICAL FALLACIES From Ad Hominem and Straw Man to the Slippery Slope and Appeal to Authority — master every major logical fallacy through real-world brain training scenarios. Each logical fallacy includes clear explanations, everyday examples, and progressive reasoning challenges that build genuine critical thinking. Whether you encounter these logical fallacies in the news, at work, or in a debate, you will spot them instantly after training. RECOGNIZE 20+ COGNITIVE BIASES Confirmation bias. Anchoring. The Dunning-Kruger effect. These invisible cognitive biases shape your decisions every day. Fallacy is the only brain training game that teaches you to detect cognitive biases in yourself and others through hands-on reasoning exercises. Understanding your cognitive biases is the foundation of stronger critical thinking and better decisions. DEBATE MODE — SHARPEN YOUR REASONING Step into real debates on real topics. Read opposing arguments, spot the logical fallacies hidden inside, and build powerful reasoning skills. Debate Mode is the ultimate brain training for critical thinking — improve how you argue, evaluate claims, and win debates using pure logic. Every debate round strengthens your reasoning and sharpens your ability to spot cognitive biases under pressure. CHALLENGE MODE — SPOT BIAS IN REAL NEWS Scroll through headlines and posts from real-world news sources. Your mission: spot the flawed reasoning and logical fallacies before time runs out. Challenge Mode is brain training for the real world — building the critical thinking and media literacy skills you need to detect cognitive biases in the news you consume daily. PRECISION IQ SCORING & PROGRESS TRACKING Your reasoning ability is measured with a precision IQ score that updates as you train. Track your 30, 60, and 90-day progress. Watch your critical thinking improve with clear insights into your cognitive growth. Brain training works best when you see results — Fallacy shows you exactly how your reasoning improves over time. DAILY BRAIN EXERCISES & 5 DIFFICULTY LEVELS Build a daily brain training habit with fresh logic puzzles and reasoning challenges every day. Maintain your streak and strengthen your mental fitness. Five difficulty levels take you from beginner to expert reasoning — keeping brain training challenging no matter your skill level. WHY FALLACY IS THE SMARTEST BRAIN TRAINING APP Other brain games train memory or math. Fallacy is the only brain training app focused on logical fallacies, cognitive biases, and real-world critical thinking. From planning a comeback against flawed reasoning to winning debates with logic — this is brain training that makes you smarter in conversations, arguments, and everyday life.
