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.

Wine, in context. OINOS is an independent platform for understanding wine - from the vineyard and cellar to the regions, people and ideas that shape what we drink. Learn how wine is made. Explore the world’s major grapes and regions. Develop your tasting. Study with purpose. And discover wine as something larger than a syllabus: a product of place, culture, history and human decisions. For those studying towards WSET® qualifications, OINOS offers structured preparation for Levels 1, 2 and 3, with lessons, maps, flashcards, Knowledge Checks and exam-style practice. For everyone else, there is simply wine. UNDERSTAND, RATHER THAN MEMORISE Why does Chablis taste different from Napa Chardonnay? What does altitude change in a vineyard? Why would a winemaker choose concrete over oak? And what, exactly, does a year of bottle age do? OINOS is built around connections. Climate, soil, grape growing, winemaking, geography and tradition are considered together - so that individual facts begin to form a picture. STUDY WITH STRUCTURE The OINOS library is organised into progressive Volumes, moving from essential principles to a more detailed study of varieties, regions, viticulture, winemaking and wine styles. For students preparing for WSET Level 1, WSET Level 2 or WSET Level 3, dedicated study tools help turn knowledge into active recall. Work through flashcards and Knowledge Checks, practise with exam-style questions, identify weaker areas and return to them. OINOS complements your formal wine education; it does not replace official course materials. KNOW WHERE YOU ARE Wine makes considerably more sense when you put it on a map. The OINOS Atlas connects appellations and regions with climate, landscape, grape varieties and wine styles - from Burgundy and Bordeaux to Barossa, Mendoza, Mosel and Marlborough. Geography stops being a list of names and becomes part of the explanation. LEARN WHAT IS IN THE GLASS Tasting is where theory becomes tangible. Develop a systematic approach to observing wine, build a precise vocabulary and record your own tasting notes. Then go further: connect acidity to climate, aromas to variety and development, structure to extraction, and style to decisions made months or years before the bottle was opened. BEYOND THE SYLLABUS There is the wine you need to know for an examination. And then there is everything that makes you want to know it in the first place. OINOS looks beyond study to the wider world of wine - its producers and places, histories and traditions, changing ideas and contemporary culture. Because passing an exam is useful. Knowing why you care is better. OINOS Wine is an artwork composed by nature and perfected through time. OINOS is an independent educational platform and is not affiliated with, endorsed by or approved by the Wine & Spirit Education Trust (WSET).
