How To Draw Diagram Science

Most apps show you a finished diagram. In the exam you have to draw one, and name every part.

Pick a diagram and work on it four ways.

VIEW THE DIAGRAM

The finished diagram with every part numbered. Tap any number and the name appears right there on the drawing. The full list sits underneath, and you can zoom in on a crowded corner.

LEARN TO DRAW IT

Build it up one small step at a time on a numbered grid.

- The part to draw now is shown in red. Everything already drawn stays grey, so you can see where the new lines fit.
- Each step has a short, plain instruction, and the area to draw in is highlighted.
- The grid is numbered along every edge. Tap any point to read its column and row, so you can put each line in the same place on your own paper.
- The app remembers where you stopped in every lesson.

TAKE A QUIZ

A marker lands on a part of the diagram and you choose its name from four. Answer, and you see straight away whether you were right and what the correct name was.

LABEL THE DIAGRAM

Every part is numbered and you pick its name from a list. Each name is used once. When you check, whatever you got wrong is crossed out with the right name beside it — no pretending you did better than you did.

Your best score in the quiz and the labelling is kept for each diagram.

FIND ANYTHING FAST

Search the list by diagram, by subject, by chapter — or by any part name. Type "aorta" and the heart comes up. Type "retina" and you get the eye.

WHO IT IS FOR

Class 10 students preparing for board exams, and anyone who has to reproduce science diagrams under exam conditions.

This is an independent study aid. It is not affiliated with, endorsed by, or connected to CBSE, NCERT, any state board, any school, or any government body. It does not replace your textbook or your teacher.

Recent changes:
Anonymous usage counting has been added, so we can see which diagrams students actually use and which to add next.

It records which screen you opened, nothing else. No name, no account, no device ID, no advertising ID, and nothing you draw or score. It goes to our own server, not to Google or any other company.

That is why the app now asks for the internet permission. It is the only one, and the app refuses every other address. Everything still works with no connection.
