Red Marker

Photograph the page; RED MARKER shows what’s correct and what needs work.

RED MARKER turns an evening of marking into a few minutes. Point your phone at maths worksheets, capture the page or use smart scan for a whole booklet, and get instant feedback: a tick when a page is fully correct, or red markers on answers that need checking.

Built for parents, teachers and tutors using ages 4-10 maths worksheets. Spend about 3 minutes instead of 45, and use the time you save to help children understand their mistakes, not just find them.

How it works

- Capture: Point your phone at the worksheet and tap Capture, or use Smart Scan to capture a full booklet in one go.
- Review: See a tick for a fully correct page, or which answers need attention, with correct and incorrect answers clearly highlighted.
- Organise: RED MARKER can recognise student names and classes so you can group by folder and track progress over time.
- Export: Export results and keep a record of progress over time.

What it supports

- Ages 4-10 drill-style maths: addition, subtraction, multiplication, division
- Worksheets and handwritten maths
- Filtering and organisation by class and student

The app uses your device camera and AI to read and check handwritten answers. You stay in control: review every result, track progress, and use the time you save to teach.
