DiagramQuiz

DiagramQuiz was built by a medical student who needed a better way to study anatomy, and couldn't find one.

DiagramQuiz turns any diagram into a powerful study tool in seconds. Import a diagram from your photos or take a picture directly in the app, then instantly detect and hide the labels to generate a clean, blank version. Print these unlabeled diagrams to study offline, quiz yourself by hand, or use them as classroom worksheets.

Ever want to study using the exact visuals from your textbook or course materials? With DiagramQuiz, you can. Take a photo of any image from a textbook, handout, or presentation slide and instantly convert it into a personalized study guide.

Once your diagram is set up, choose how you want to study:

On iPhone, jump straight into Matching Mode: pinch and pan to explore your diagram up close, then quickly assign each shuffled label to its numbered spot. Fast, precise, and built for one-handed studying on the go.

On iPad, you've got even more ways to study: type in answers and get instant feedback, save everything for a test at the end, or use Matching Mode's drag-and-drop, pick up a chip, drag it onto the diagram, and drop it on the right spot. Move it if you change your mind, then hit Check Answers to see your results.

Designed to work with any type of diagram, anatomy, biology, engineering, geography, or custom visuals, DiagramQuiz is flexible enough for students, educators, and self-learners across disciplines. It's a simple, visual-first way to study, practice, and retain complex information more effectively.
