The problem
Many quiz applications centre generic international content rather than knowledge that feels locally relevant to Zambian players.
The response
ZamTrivia packages Zambia-focused questions across ten categories with random play, timed answers, score calculation and a device-local leaderboard.

Quiz state across many paths
Timer expiry, incorrect attempts, skips and replaying skipped questions all needed to advance consistently without losing the final score.
