One Website. Every Physics Lesson You’ll Ever Need.
Full curriculum coverage, real interactive simulations, and practice that adapts to exactly where you’re stuck.
Built by a physics teacher, for physics students. Free forever for the core curriculum — no credit card needed.
Handwritten Worked Solutions
Get a practice question wrong and watch the full worked solution, written by hand by your teacher. Zoom in, pan around, go full screen.

Wherever You’re Studying, We’ve Got It
One platform, built to cover every major curriculum.
Why Students Stay Here
Not another content library. A place to actually learn.
Simulations You Can Actually Break
Not diagrams — real physics engines. Load a spring past its limit and watch it deform. Solve a circuit that's actually being solved, not animated.
Practice That Knows Where You're Stuck
Question-by-question practice with mastery tracking, IXL-style. Get something wrong, and we point you straight back to the lesson and simulation that fixes it.
One Class, One Login
Join your teacher's section with a code, and everything they assign lives in the same place you study — no separate app for homework.
Built By Someone Who Actually Teaches
Every lesson, simulation, and question exists because a real physics class needed it — not because it filled a content template.
See It In Action
A few of the simulations you’ll actually use, not just look at.
