An App

Sat, 23rd Aug 2025

I'm going to have a crack at createing a Duolingo-style times tables app with competitive multiplayer features. Kids race against timers to solve multiplication problems, with the ability to sabotage friends' streaks using power-ups when they're performing well.

Core Objectives:

  • Gamified learning with streak systems and achievements
  • Timer-based challenges with adaptive difficulty
  • Multiplier attacks to disrupt opponents' hot streaks
  • Progressive difficulty scaling beyond traditional 12x tables

Tech Stack Planning:

  • Frontend: Likely React Native for cross-platform (exploring Flutter and Swift aswell)
  • Backend: Node.js with Socket.io
  • Database: PostgreSQL
  • Authentication: Firebase

Key Features to Build:

  • Personalised but balanced difficulty adjustment based on general performance
  • Friend modifiers with streak-breaking power-ups
  • Adaptive timers that speed up with success - tighter timers equate to more powerful power ups
  • Progress tracking and group/team/clan dashboards

Target launch: 6 months. Starting with MVP focusing on single-player mode, then adding multiplayer sabotage features.
