ZDMR - Digital Mark Reader

ZDMR — Check. Read. Grade. Accurate.

Correcting multiple-choice exams is now as easy as taking a photo. ZDMR (Digital Mark Reader) turns your phone into a professional answer sheet (OMR) checker — without expensive scanners and without sending student data to any servers.

🎨 DESIGN YOUR OWN ANSWER SHEETS Create your own ABO templates with a drag-and-drop editor: auto-numbered multiple-choice blocks, bubble-style name and NISN columns, student ID number, date of birth, A/B question packs, school logo, filling instructions, and even ink color options. Design app-style magnetic snaps keep everything neatly aligned, and an automatic validator prevents misprints. Export to print-ready PDF — templates can be reused between exams.

📷 SCAN AS QUICK AS SNAP: Point the camera at the answer sheet — done. Four corner markers let ZDMR automatically straighten tilted, upside-down, or shaded photos, then read hundreds of bubbles in an instant. Doubtful readings (thinly filled in, multiple answers) are flagged for review, not guesswork.

✍️ AUTOMATIC PG + STRUCTURED ESSAYS Multiple-choice grades are automatically calculated with weighting per question (including bonus questions). For essays, ZDMR crops each student's answer area from the photo so you can grade from the screen — per question across students, more fairly and quickly — with weighting locked in from the start.

📊 ONE-PUSH SUMMARY Total grade, average, item analysis (% correct per item), and even individual student answers per item — all automatically summarized and ready to be exported to Excel and shared via WhatsApp, email, or Drive.

👥 CLASSES, ABSENCE & GRADEBOOK More than just OMR. Manage student lists per class, record attendance (Present/Permit/Sick/Alpha) with percentage recaps, and combine grades between exams into the Gradebook with automatic category weighting (Assignments/Daily/Mid-Term/Final Exam), Minimum Completion Score (KKM), and grades. Print PDF report cards per student or class at once.

🌐 BIO-LANGUAGE Complete interface in Indonesian and English, can be switched anytime from the Profile menu.
