Purpose of App Review

  • How useful is this app as an EKG reference tool?


PocketSim is a medical app that can be used to look up and study 23 EKG patterns.

This app contains examples of various waveforms with short but useful descriptions as well as flashcards and quizzes.

User Interface

The app opens up with a screen that gives the user the option to browse through the different EKGs, study the flashcards or take a quiz.

Under the waveform option, several categories of EKGs are presented as well as an option to choose from a list of all waveforms.

Once one of the categories is selected, a scroll bar with a list of different EKG patterns appears as well as a picture of that specific EKG pattern and an option to view a description of that waveform.

The descriptions give a short summary of what can cause that specific pattern as well as the specific measurements of that particular wave that can be expected to be seen on an EKG.

The app also includes a flashcard section that can be very useful to learn each of the patterns. The flashcard section actually provides even more information about each wave such as descriptions of the waves rhythm, rate, PR interval, etc.

The quiz section in the app allows the user to choose quiz questions based on a description of the EKG pattern or a picture of the actual EKG pattern. This allows the user to learn how to interpret EKGs as well as reinforce the clinical and technical associations of each.

  • Free


  • Very easy to use
  • Great short descriptions for each wave pattern
  • Flashcard and quiz options make this app great for learning in addition to being a great reference tool


  • It would be nice if the information that is in the flashcard section could also be available in the waveform section
  • The app only includes single EKG waveforms rather than 12 lead EKGs

Healthcare workers that would benefit from the app

  • Any healthcare worker who is looking for a pocket reference tool to learn and look up various single lead EKG waveforms.


  • This medical app makes learning and looking up different EKG patterns very convenient.
  • The app includes images of many EKG waveforms including short descriptions for each as well as sections that include flashcards and quizzes for learning. This is a great medical app for students who want to learn how to read single EKG waveforms.
  • As of publish, an Android version is not available.
