Geopolitics explains why Russia invaded Ukraine, why the US keeps 750 military bases overseas, and why a 39-kilometre strait near Iran can move the global economy. Orbis teaches how the world actually works — in bite-sized lessons that fit your commute. An IR scholar might study why the UN passed a resolution. A geopolitical analyst asks why it doesn’t matter. Orbis teaches you to think like the second one: no jargon, no dry academia, just causation — who wants what, who can take it, and why geography keeps deciding the winners. LEARN GEOPOLITICS, PROPERLY • 500+ lessons across every region and era, 5–15 minutes each • Courses include: World History: 12,000 Years of Civilization · Geopolitics Foundations · Russia: Empire to Superpower · China–Taiwan: The Unfinished Civil War · The Korean Peninsula · Rome: From Republic to Empire · The British Empire · The Ottoman Empire · The Cold War · The Chip War · Iran • Written to be finished — every lesson explains why, not just when READ THE NEWS. UNDERSTAND WHY. • Daily news with context: every headline linked to the history and power dynamics behind it • Follow the world’s flashpoints with the background that makes them make sense REMEMBER WHAT YOU LEARN • 3,500+ flashcards with spaced repetition • Quizzes after every lesson • Review sessions that resurface what you’re about to forget EXPLORE THE WORLD • Profiles of countries, leaders, and conflicts • Strategic chokepoints, from Hormuz to Malacca • GDP rankings, military balances, alliances, and nuclear arsenals — the numbers behind the power BUILD THE HABIT • Streaks, monthly recaps, and progress tracking • Five minutes of geopolitics a day is enough to read the news differently WHO ORBIS IS FOR • News readers who want the why, not just the what • Students of international relations, politics, and world history • Investors and professionals who need to understand country risk • Anyone who wants to know how power actually works Terms of Use: https://learnorbis.com/terms Privacy Policy: https://learnorbis.com/privacy-policy

Verdict
The clearest difference is ads: Roll & Count at none against Orbis's shown. Orbis's advantage is update cadence (every 8 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
