Better 1UP

Better 1UP turns times tables into a fast-paced multiplayer game. Answer multiplication problems against the clock, climb 8 progressive tiers, and race classmates in live classroom sprints — all without creating an account or sharing any personal data. HOW IT WORKS • Sprint: 60 seconds, back-to-back problems. Score is weighted by difficulty — easy facts count less than hard ones. • 8 Tiers: Start with the easy facts and unlock harder pairs as your accuracy climbs. Reach Tier 7 for extended mode (×11–×20). • Classroom Mode: Teachers launch a group sprint; students join live and compete on a real-time leaderboard. SMART DIFFICULTY The app adapts to your exact level. Problems come from your current tier only — never too easy, never too frustrating. Mastery is tracked silently in the background. PRIVACY BY DESIGN No account needed. No name, email, or device ID is collected from students. Learning progress stays on your device. No ads. No tracking. GDPR-compliant. FOR TEACHERS Create a classroom in seconds. Launch a sprint for your whole class. Watch scores update live. Students join with a classroom code — no app management required. 8 LANGUAGES English, Deutsch, Français, Nederlands, Türkçe, Українська, العربية, 中文
