BullDozer turns the world into numbers you can actually explore. Compare countries across 270+ indicators covering the economy, society, business and the environment — with fast charts, world maps, country profiles, a data quiz and Ask AI. Free, with no account, no ads and no tracking. ASK AI (BETA) Pick a country and ask in your own words — "How healthy are people?", "Is the economy growing?". The answer is written from BullDozer's published figures with the source and year of each, and any number not found in our data is held back. AI answers can be wrong, so the figures are always shown alongside. The app asks once before your first question is sent. CHARTS & RANKINGS Browse 270+ indicators, search them, filter by topic and rank every country on any of them. Switch periods to see how the ranking changes, and tap any country bar to open its trend over time. COUNTRY PROFILES Pick a country from a searchable list with flags and get the full picture: a map zoomed to the country, headline macro figures, a short encyclopedic summary, and every available indicator grouped into Statistics and Surveys. COMPARE Put up to 5 countries side by side on any indicator and see who leads, who lags and how the gap has changed. EXPLORE Plot any indicator against any other across all countries in a scatter view — a quick way to spot how wealth, health, demography and values relate. WORLD MAPS Every dataset has a world choropleth coloured by the data. Tap a country on the map to see its trend line. DATA STORIES A feed of featured stories with live mini charts and quick facts — a fresh angle on the numbers every time you open the app. QUIZ "Guess the Country": data facts are your hints, and the fewer hints you use, the higher your score. A painless way to build real data literacy — for students, teachers and anyone who loves world facts.
