40 — Just the Facts

40 answers your questions out loud — and only with the facts. Ask anything by voice, and 40 explains it in plain language, using places and things you already know. How big is a lake? 40 might tell you it's "about 60 times the size of Central Park." Why 40 is different: • Facts first. 40 checks a verified knowledge base before answering and shows you the source. If it doesn't know, it says so — it never makes things up. • Made for listening. Big buttons, a clear voice, answers read aloud — easy for everyone, including older adults. • Explained your way. Sizes, heights and distances become familiar comparisons, so they're easy to picture. • Live World Cup. Ask about the 2026 World Cup — scores, players and records, kept up to date. • Your language. Use 40 in English, Traditional Chinese, or Simplified Chinese. Just tap the microphone and ask.
