About this app

Use your phone to mark maths worksheets in seconds. See which answers need practice, keep each child's work organised, and spot learning gaps early, 80–93% faster than marking by hand.

Point at a worksheet, tap Capture or use Smart Scan to move through a full booklet quickly. You’ll see a green tick when a page is correct, or red markers showing exactly what needs checking, so you spend time teaching instead of searching for mistakes.

Perfect for parents, teachers, and tutors who want faster homework marking.

How it works

• Capture — Scan one worksheet or a whole booklet. Smart Scan moves page-to-page automatically.
• Review — See correct answers instantly; handwritten responses supported.
• Organise — Names and classes recognised so work sorts into folders automatically.
• Filter — Enter filter criteria to locate worksheets instantly.
• Export — Save results and build a progress record over time.
• View Progress — Accuracy charts show improvement and highlight where support is needed.

What it supports

• Drill-style maths for ages 4–10
• Printed worksheets and handwritten answers
• Organisation by class and student

You stay in control: every result is visible for review, with progress you can track over time.

Turn three-quarters of an hour of marking into three minutes, and use the time you save helping children understand their mistakes.
