About

Corpus 4AR

Read full description

Corpus 4AR turns your iPhone into a window into the human body. Point the rear camera at a person and watch an anatomically accurate 3D skeleton, organs, and muscles track their body in real time โ€” right where they actually are. BUILT FOR MEDICAL STUDENTS AND CLINICIANS โ€ข Study surface anatomy and organ relations on a real body, not a textbook diagram โ€ข Hand a classmate the phone and point to your own spine, ribs, or kidneys โ€ข Show a patient where their heart sits or why their shoulder hurts โ€” in 30 seconds at the bedside WHAT YOU CAN SEE โ€ข Skeleton โ€” full 3D bones tracked to the body, with anatomical labels โ€ข Organs โ€” heart, lungs, liver, kidneys, digestive tract and more, in place inside the torso โ€ข Muscles โ€” major muscle groups layered over the skeleton โ€ข Latin and English names; search any structure and focus on it PRIVATE BY DESIGN โ€ข Everything runs on your device โ€” no accounts, no sign-in, no cloud โ€ข No analytics, no tracking, no ads โ€” rear camera only POWERFUL FREEMIUM Every feature is included free. If it helps you, an optional tip supports development โ€” but it unlocks nothing, because there's nothing locked. Corpus 4AR is an educational and reference tool. It is not a medical device and is not intended for diagnosis, treatment, or clinical decision-making. Requires an iPhone with an A12 chip or later for AR body tracking.
