With Quick Key you can send a quiz to your students’ Chromebooks, laptops, or mobile devices (BYOD). Pencil and Paper Classroom? You can grade 100 paper tests in less than 5 minutes, using nothing but the camera on your iPhone or iPad, and our scantron-style bubble sheets are 100% free! Quick Key is the only mobile grading solution that is secure enough for districts, affordable enough for schools, and easy enough for everyday classroom use. Are you the leader of a 1:1 school, or a district in transition to 1:1? Quick Key effortlessly combines results from 1:1 classrooms and paper classrooms. And it provides automatic top-level reporting of key data, so you can focus on student growth, not managing your data. Quick Key was originally built for teachers doing ungraded assessment for learning and frequent formative assessment in the classroom, using nothing but their iPhone or iPad. But even if you don’t use daily exit tickets, Quick Key is perfect for quizzes, unit tests, district wide benchmark assessments, midterms and finals. It completely replaces the need for a scantron machine.

ReceptionRating · Positive reviews · Number of ratings

PaperScorer Scanner holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Quick Key Mobile Grading App has 226 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of Quick Key Mobile Grading App's written reviews are positive against 25% of PaperScorer Scanner's, so the app with the better star average is not the one people write more warmly about.

Quick Key Mobile Grading App ships an update every 3 weeks, PaperScorer Scanner every 5 months. The most recent releases landed on October 6, 2026 and September 18, 2026 respectively.
