Pick a game
Nine of them, and it tells you how many people are playing today.
Six trivia questions a day
Answer all six, then see how you did against everyone else.
Today's score
Out of a thousand, with your time and how many you got right.
Streaks and leaderboards
Daily, all-time, and a league table that moves every week.
You open it, tap Daily Trivia, and answer six multiple-choice questions with a fact after each one. If you want more, there are four other daily games on the home screen, and a real-time head-to-head game called Chase you play against a friend. Streaks, friends and leaderboards sit behind it all; none of it nags you.
Toolkit: Flutter on the front, Firebase on the back. Auth, Firestore, Cloud Functions in TypeScript, messaging and analytics. Chase is a Firestore document per match with a server-authoritative buzz timestamp, which was harder to get right than it sounds.
All the content ships with the app, so gameplay works offline. Streaks survive a skipped day if you play any game, and the questions can be read aloud for anyone who would rather listen.
