AngioView is a free 3D simulator for learning coronary angiography. It's meant for cardiology fellows, cath lab nurses and techs, interventional cardiologists, and anyone interested in coronary anatomy! One of the hardest parts of cardiology fellowship is building a 3D map of the coronary arteries in your head, and knowing how it turns when the view goes cranial or caudal, LAO or RAO. AngioView lets you practice that on an anatomical model, with no patient on the table and no radiation. It is the tool I would have loved to have in fellowship. WHAT YOU CAN DO • Move the C-arm yourself: drag the image, use the rotation and angulation controls, or drag the C-arm in the room • Go straight to any standard view, such as the spider, RAO caudal or LAO cranial • Study the left coronary, the right coronary, or both • Switch between right-dominant, left-dominant and co-dominant anatomy, with or without a ramus intermedius • Turn on segment names and colors, on the angiogram and on the 3D heart • Pick a segment and see which angles show it with the least foreshortening and overlap • See where the detector sits in every view • Works offline. No account, no ads, no tracking. WHO IT IS FOR Cardiology fellows, interventional cardiologists, residents, cath-lab nurses and technologists, students, and anyone curious about how a coronary angiogram is read. GOOD TO KNOW AngioView shows one generic, normal coronary tree, with no patient cases and no stenoses. The anatomy is built from openly published datasets and measurements, all credited in the app. AngioView is an educational simulation. It is not a medical device and must not be used for diagnosis, treatment or any clinical decision.

Verdict
The clearest difference is update cadence: AngioView at every 3 days against ECGRef's every 3 weeks. AngioView also leads on iOS requirement (18.0 vs 26.0). On price, rating, review sentiment and ratings volume there is nothing between them.
