How it works
OMR stands for Optical Mark Recognition — the technology that reads filled bubbles on answer sheets. The app uses your phone's camera to detect which bubbles are filled, match them against an answer key you've set, and calculate a score instantly.
You don't need a scanner or any special equipment. Just good lighting and a steady hand. The app works with standard multiple-choice sheets and handles sheets you print yourself.

Who uses it
Teachers who run paper-based quizzes and exams are the main users. Instead of manually checking 30 answer sheets, they scan them one by one and the app does the comparison. It's also useful for tutors running practice tests, university lecturers with large class sizes, and anyone else who needs to process bubble sheets quickly.
