• How useful is this app in training medical professionals to use an otoscope and identify key ear pathology, such as ear infections.


OtoSim Companion is a medical app to be used while learning how to use an otoscope.

The app is used in combination with a device that resembles a real ear called the OtoSim Simulator.

The app can also be used as an otologic atlas since it is full of great images and text that show and describe the normal ear as well as various pathologies.

User Interface

The app is very user friendly and opens up with the first page of the text.

Each new chapter can be opened by selecting the chapter index at the top left of the screen. Each chapter has several pages of text and pictures explaining how the normal ear anatomy and pathologies of the ear may look through an otoscope.

Each of the images can be zoomed in on by clicking on them, giving a clear high definition image that is great for learning purposes.

Healthcare workers that would benefit from the app

  • Any healthcare worker who uses an otoscope.


  • This app is a great tool to use when learning how to use an otoscope and how to analyze the different ear pathologies that may be encountered. This app can be used with the OtoSim Simulator which is what it was developed for but can also be used as a otologic reference due to the many images included within the app,
