Rusti

Each morning, ten questions on the basics every adult learned — and most have forgotten.

Multiplying fractions. World capitals. Body systems. Vocabulary roots. The stuff that was easy at ten and hits different at thirty-five.

Play the daily ritual solo, climb the friend leaderboard, or get pulled into a household showdown with the kids. Then challenge a friend head-to-head on a single subtopic — multiplying fractions, world capitals, parts of speech — and see who's actually rusty.

Privacy-first by construction. No accounts to create. No tracking. No ads. Game Center handles friends; iCloud handles the household, challenges and daily scores.

In the daily ritual:
• Ten questions per day, sixty seconds each
• Single attempt — share your spoiler-safe scorecard at any time
• Friend leaderboard via Game Center
• Family household leaderboard shared through iCloud, with kid sub-accounts that stay COPPA-clean by construction

Unlocks with Rusti+:
• Practice Mode — unlimited practice quizzes that start with questions you've already seen and won't preview your next month of dailies
• Family Dashboard — parent-facing weekly per-kid report
• Challenge Mode — initiate head-to-head challenges on any subtopic, accuracy plus speed scoring
• Plus replays of any quiz you've played, detailed per-subject stats with your current and longest streaks, your score trend and consistency, a monthly streak freeze, themed share artifacts, a reminder at the time you choose, and unlimited kid sub-accounts
