Our goal is to provide a realistic and simple means for surgeons and surgical trainees to practice pre-operative markings in a low-stakes and fun environment, to increase accessibility to modern surgical marking techniques for a variety of conditions.

Where can I download the app?

The app is completely free and downloadable from the apple app store.

What equipment do I need?

An apple device (either iPhone or iPad) with iOS 16+ installed. An apple pencil and iPad are recommended for optimal performance but not required.

I disagree with your answer keys. Who determined the correct placement of markings?

Surgical markings are incredibly personal and case-specific, with a variety of techniques published and accepted in the medical literature. The current answer keys are derived from our surgeons' method of drawing pre-operative markings. For more questions, please find our contact email below.
