## What is HistoLogic?

HistoLogic is a free study resource for people trying to learn tissue microscopy. It was designed for students in graduate medical education programs. Users of the app gain access to hundreds of high-quality images and helpful descriptions of the important cells, tissues, and structures in multiple organ systems created by faculty at University of Illinois College of Medicine Peoria.

Explore mode allows students to learn about cells in different organs and their functions in the body. Toggle between low and high magnification images of each organ. Specialized cells are clearly highlighted, and the underlying text describes their appearance and role.

The app ​also contains Time Trial mode with multiple choice questions at escalating difficulty levels. There are over 350 different questions to test your knowledge across multiple organ systems. The Time Trial questions challenge you to beat your old score with each login. The question order is randomized with each gaming session, and the app adapts to your previous play through.

True histology pros can test their skill in Hot Streak mode. This mode forces you to answer all 90 questions for an organ system in a single sitting. One wrong answer boots you back to the beginning and resets the question order. Can you make it all the way to the end? 

Features:
• View hundreds of histology images across multiple organ systems.

• Toggle between high quality images at low and high-power magnification.

• View hand-drawn outlines for important cells, tissues, and structures.

• Examine organs and learn their important histological features with Explore mode.

• Review histology questions in Time Trial mode with three difficulty settings.

• Strain your brain to answer all 90 questions per organ system in a single run of Hot Streak.

• Enjoy endless replays as questions order is randomized for each session.

• Detailed rationale for each question is clearly described in case you answer incorrectly.

• Randomization adapts to your scores; previously missed items are prioritized in later game sessions.

• Additional organ systems to come.
