3 Quick Maths

A lightweight Android app for practicing derivatives and integrals (mainly trig). Think Kahoot or Duolingo but faster, lighter and without the corporate bloat feel.

Why I Made This

I needed practice for my ODE class but couldn't find any good resources online. Every mobile app I tried was slow, bloated with tokens and currencies, and constantly hit me with subscription popups. So I built my own - no ads, no accounts, no BS. Just math practice.

And yes the name is ironic and is a reference to Big Shaq's - Man's Not Hot: "2 plus 2 is 4 minus 1, that's 3, quick maths."

Features

  • Practice Mode - Work through topic groups with best score tracking
  • Infinity Mode - Endless random questions with streak counter
  • Haptic & Sound Feedback - Vibrations and audio cues for answers
  • Progress Persistence - Scores saved locally
