ScanGrader vs ExamScan

ScanGrader is a complete solution for teachers to prepare and mark multiple choice tests using the device camera as a scanner. MAIN FEATURES ------------- ADVANCED IMAGE PROCESSING ScanGrader has developed an image-processing algorithm that consistently delivers precise results. COSTUMIZABLE ANSWER SHEETS Build personalized answer sheets directly from your iPhone or iPad, from 1 to 100 questions, with one or two answer sheets per page (in this case, you need to cut the page in half to distribute to students). You can define up to four labels, which will be printed on the answer sheets (name of school, name of class, teacher's name, data, etc.). You can also choose whether the answer sheets should contain a field for the students' signatures. VISUALIZE AND ANALYSE THE RESULT ScanGrader provides an Item Analysis tool, presenting, for each question, the difficulty level, the discriminant factor, and the frequency distribution of alternatives. You can see the results grouped by class, test, or students. All results can be seen using any of the groups: they are only grouped differently. If a test is applied to only one class, there is no difference if you choose to see the results by class or test. But if a test is applied to more than one class, choosing the class grouping will show the results for students in that class, while choosing the test grouping will show the results for all classes in which the test was applied. For class and test groupings, ScanGrader provides information and statistics about the grading: maximum points scored, minimum points scored, average points, standard deviation, median points, and others. EXPORT THE RESULTS You can export the results as a spreadsheet file in two formats: 1) Normal (ideal for importing the results of a test into your computer or on the school's server) 2) Complete (to use external tools for Item Analysis). REPORTS You can generate two types of reports as a PDF file: 1) Simple (a list of the students and their respective scores to post to the students) 2) Complete (a page for each student, containing a text with the student's choices for each question, the student's score, an image of the scanned answer sheet, and an image showing the result of the grading) TYPESET YOUT TEST To streamline the test preparation, keep the test's questions in a spreadsheet file (see the format required inside the app). Then, use the Typeset Questions tool to produce an elegant and professional PDF file to distribute to the students. You can typeset your test in one or two columns, and each question can also have an image, if necessary. You can also choose to set the key automatically for the test, with information kept in the spreadsheet file. SYNC BETWEEN DEVICES Sync students, tests, classes and results between your iOS devices using iCloud. SUBSCRIPTION Each time you use ScanGrader to grade a student answer sheet, that is counted as one 'grading'. Users without a subscription have access to all functionalities, but with a limit of 50 'gradings' per month (non-cumulative).  Users with an Annual Subscription (the only one available for ScanGrader) enjoy unlimited gradings throughout their subscription period.

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.
