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.

Built around timeless influence principles and modern behavioral insight, Persuasion turns the psychology of persuasion into practical skill. Inside the app, learners can explore how influence really works, why people say yes, why they resist, how trust is built, and how stronger communication creates better outcomes in work and life. WITH PERSUASION, USERS CAN: • Learn core principles of influence in a clear, engaging format • Build stronger instincts for communication, trust, credibility, and buy-in • Understand concepts like authority, social proof, reciprocity, scarcity, framing, and more • Apply persuasive thinking to sales, leadership, marketing, negotiation, interviews, presentations, and everyday conversations • Strengthen confidence in high-stakes moments where words matter most DESIGNED FOR: • Sales professionals • Founders and entrepreneurs • Marketers and creators • Managers and leaders • Job seekers and professionals • Students • Anyone who wants to communicate more effectively Persuasion is not about manipulation.
