Bones of the Body
Learn Anatomy on a 3D Skeleton
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Spin a real 3D skeleton, zoom in close, and tap each bone as it is called out. Every bone is free, from skull to toes. Flash cards, voice answers, and speed mode too.
Learn every bone in the human body on a real 3D skeleton you can spin, zoom, and tap.
Bones of the Body turns anatomy into a game. Spin the skeleton with one finger, pinch to zoom in close, and tap each bone as it is called out. Get it right and the bone lights up green. Miss it twice and the camera swings round and zooms in to show you exactly where it is, so you learn from every mistake.
SKELETON TEST
Find all the bones on the 3D skeleton, from the skull to the toes. Color-coded results show what you knew on the first try, what took a second try, and what to practice next.
THREE QUIZ MODES
- Bone Names: name the bone from the skeleton
- Common Names: kneecap, shinbone, collarbone, and more. Learn the real names behind the everyday ones
- Bone Clues: find the bone from a fun fact, like the longest bone in the body or the only bone that touches no other bone
FLASH CARDS
Flip through cards that light up each bone on the skeleton, grade yourself, and open any bone in 3D to explore it from every angle. Heart the ones you want to see again.
VOICE ANSWERS
Say the bone's name out loud and the app checks it for you. Correct answers ding and move on. Misses go straight into your review pile.
REVIEW MISSED
Every bone you miss comes back for review until you get it right.
DAILY STREAKS
Build a learning habit with streak tracking and badges.
