Scan & Grade Bubble Sheets
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
OMR Grader turns your iPhone into a powerful answer sheet grading machine. Teachers, professors, and educators can create, scan, and grade multiple-choice bubble sheets in seconds — no expensive hardware needed.
GENERATE CUSTOM ANSWER SHEETS
Create professional OMR bubble sheets with 50, 100, 120, or 160 questions. Choose 2 or 4 column layouts. Add your school or institute name. Download as PDF ready to print on any standard printer.
SET ANSWER KEYS IN SECONDS
Tap bubbles on screen to set correct answers. Or scan a pre-filled master sheet and the app creates the answer key automatically. Set custom point values per question and penalty scoring for wrong or multiple-marked answers.
SCAN AND GRADE INSTANTLY
Point your camera at a filled answer sheet for instant grading. The app detects the sheet, reads every bubble, and shows the score in real time. Works with printed sheets from any standard printer.
BATCH GRADING FOR LARGE CLASSES
Have a stack of 100 or more sheets? Use any document scanner to digitize them, then load all images into Batch Scanner. The app grades every sheet automatically — saving hours of manual work.
VIEW DETAILED RESULTS
See each student's score with a color-coded annotated sheet showing correct, incorrect, empty, and multiple-marked answers. Identify which questions students struggled with most.
EXPORT AND SHARE
Export results as CSV spreadsheet, PDF report, or ZIP archive. Share with colleagues, administrators, or parents easily.
