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 library — 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 Files 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 "Grade 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. • Works on iPhone and iPad. • 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 pencil or pen, one bubble per question. • Download free sample sheets right from the About screen in the app. ExamScan is free with a starter batch of grading credits; earn more through daily login, sharing the app, or watching ads. The app shows advertisements (filtered to general-audience content). Feedback is welcome at: Rubi.ExamScan@gmail.com

Verdict
The clearest difference is in-app purchases: ExamScan at none against Check Answer's 4. ExamScan also leads on update cadence (every 2 days vs every 4 days). Check Answer's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
