ExamScan: Answer Sheet Grader

ExamScan helps teachers grade paper multiple-choice tests just by photographing the answer sheet — fast, accurate, and processed entirely on your device.

DEAD SIMPLE — ONLY 2 STEPS
• No templates to build, no setup, no special app forms to print.
• Use the standard answer sheets you already have: (1) load the answer key, (2) snap a photo — done.
• A sheet came out skewed or mismarked? Fix it right on the sheet — no need to reconfigure anything.

GRADE IN SECONDS
• Snap a photo or pick from your gallery — the app detects filled bubbles and scores the sheet.
• Automatically reads the student ID and exam code.
• Supports sheets with 3, 4, 5, or 6 options (A–F).

BATCH GRADING
• Pick many photos from the gallery to grade a whole class at once.
• Review the result list — error sheets are clearly highlighted in red.
• Re-grade any single sheet if a photo wasn't good enough.

EXPORT TO EXCEL
• Create an .xlsx file with each student's score, named the way you like.
• Share it or save it to your device in one tap.

PRIVATE — GRADE RIGHT ON YOUR DEVICE
• All recognition and scoring happen right on your device — grading works even offline.
• No accounts, no login; your answer sheet images and results are never sent to a server.
• The app uses Firebase for anonymous analytics and crash reporting to improve the app (never your answer sheets or results). See our Privacy Policy.

CONVENIENT
• Built-in "Try with sample sheets" demo to try instantly — no setup needed.
• 5-language interface: English, Vietnamese, Indonesian, Portuguese, Spanish — auto-selected from your device language, switch anytime.
• A "frame check" image shows you why a sheet failed.
• Report a problem sheet by email with attached images for support.

ANSWER SHEET REQUIREMENTS
• Standard A4 sheet with 3 orientation marks at the corners.
• Fill solidly with a 2B (or softer) pencil or pen, one bubble per question.
• Download free sample sheets right from the About screen in the app.
