Learn 31 major muscles, front and back, with a clickable body. Study, practice, then pass a graded test to earn a printable certificate. Works offline.

WHAT IS INSIDE

Study Lab. Tap any of 31 major muscles for its real anatomical name, the movement it makes, and a fact worth repeating at dinner. A read-aloud button reads it out loud.

Front and back. The body has a Front tab and a Back tab, because half the muscular system is behind you. The game turns the figure around when your student needs the other view.

Opposing pairs. The idea most worksheets skip. Muscles cannot push, only pull, so they come in pairs: the biceps bends the elbow, the triceps straightens it. Every paired muscle names its partner.

Challenge. Fast, replayable practice. Find a named muscle on the body, or name the one that is glowing, with streaks tracked.

Final Test. A graded 20-question test that stays locked until all 31 muscles are studied, so it is a real finish line. Score 16 or better and a printable Certificate of Achievement unlocks.

FOR REAL HOMES AND CLASSROOMS

Each child gets a private, anonymous code instead of a name, so several students can share one device with separate progress. Parents and teachers can enter a code to check progress without changing anything. No names, no email, no sign-in, nothing collected.
