More than just a geography quiz, GeoGoat helps you learn the 198 countries of the world once and for all! → 3 minutes a day Each session introduces you to new countries and the day’s revision. Your working memory can only take in 5 to 7 new items at a time, and GeoGoat stops when you’ve had enough. This ensures long-term retention. → An engine inspired by cognitive science You learn a country today. You’re asked about it again the very next day. Then a week later. Then two weeks later. Each time you get it right, the interval gets longer: that’s how a memory goes from ‘seen once’ to ‘known for good’. Get it wrong? No worries, try again the next day: consistency is key. Spaced repetition, dual coding, cognitive load: these aren’t just buzzwords on a marketing page – GeoGoat will rekindle your joy of learning. → Recall, not recognise Picking the right answer from four options is something everyone can do – forget those other bogus quizzes. Here, we give you a name and you have to place it yourself on a 3D globe, with no reference points. It’s this effort to recall that cements what you’ve learnt. → Three things to memorise Countries: place the 198 countries on the map, from Kyrgyzstan to Suriname. Capitals: Dushanbe, Thimphu, Ulaanbaatar. On the globe, in the right place. Flags: stop confusing Poland with Indonesia. → What GeoGoat doesn’t do No annoying notifications. No accounts to create. No adverts. Bhutan is a country. Its capital is Thimphu. Its flag features a dragon. Tomorrow, we’ll ask you again. And in two months’ time, you’ll still know the answer. GOAT or tourist? Now’s the time to find out. --- The Countries mode is free and comprehensive, covering all 198 countries. GeoGoat Pro unlocks the Capitals and Flags modes: a monthly subscription of €1.99, automatically renewed unless cancelled at least 24 hours before the end of the period, or a one-off lifetime purchase for €9.99. Payment is taken upon purchase confirmation; manage and cancel via your App Store account settings. Terms of Use: https://www.geogoat.app/cgu Privacy Policy: https://www.geogoat.app/en/privacy
