Assessment Grading App for Teachers

The fastest way through the pile.

Scan a class set, mark question by question, and walk away with scores, comments and analysis — in one sitting.

See how it works

Fewer taps. Faster marks.

Every tap the app can save you, it does.

One question, every student.

Mark Q3 across the whole class in a row. Faster, and your marking stays consistent from the first script to the last.

Tap a number, not a form.

A score keypad lives next to every answer. Score without leaving the page, then the next answer slides in.

Comment without typing.

Reusable snippets, stamps and dictation. Say it once, apply it to every script that needs it.

Nothing is ever lost.

Every edit saves instantly on your iPad. Works fully offline, and anything deleted is recoverable for 30 days.

Import. Mark. Export.

Import the stack

Scan with the camera or drop in PDFs. Nib splits the pile into one script per student.

Mark question by question

Apple Pencil in hand: tick, annotate, tap a score, drop a comment. The next answer is already waiting.

Export the results

Scores, grades and per-question analysis, ready to return to students or your department.

And there's more.
