Who knows how to use tech? Which app shows when your bus arrives, where a product is cheapest, or how to get a ride? Each game draws 10 questions at random from a pool of 20, 15 seconds each; after every answer you get a short note on what the right app is for.
How were the questions chosen? The pool has 20 questions and every game shows 10 of them in a random order, so a replay is different. They cover transport, shopping, official services, safety and everyday digital skills. Each answer was checked against the app's or organization's own page; the sources are listed below. Apps change over time; the questions were last checked on November 2, 2026.
We never ask which app is the best or cheapest, only what job it does. App names and brands belong to their owners; Who In is not affiliated with these companies. The timer does not run while you read the explanation; the next question starts when you press "Next question".
