Everything you need to actually enjoy physics
Built around the way Grade 6–10 students actually learn — short, visual, and a little bit game-like.
Interactive simulations
Drag sliders, watch forces and circuits react live — physics you can see, not just read about.
Photo & voice AI tutor
Snap a photo of a tricky problem or just ask out loud — get a clear, step-by-step explanation back.
Streaks, XP & badges
Daily streaks, star rewards, spin-to-win and a Star Shop keep practice fun instead of a chore.
Daily spaced review
A smart daily review resurfaces exactly the concepts you're about to forget, right before you do.
Misconception remediation
Wrong answers aren't just marked wrong — the app spots the misconception and re-teaches it.
Parent progress reports
A simple report shows parents exactly where a student is strong — and where they need a nudge.
