Decided to progress a personal project to market

Hi All

I've spent my entire career working for corporate firms leaving me very little time to complete and market something of my own. I recently decided to complete a personal project which launched today. Marketing isn't my forte so I'm learning from you all and hopefully will pick up some useful skills on this journey.

Looking forward to sharing ideas, collaborating and providing feedback.

RedMarker — Get your evenings back from checking maths homework

Hey Product Hunt,

I built RedMarker because worksheet marking doesn t scale especially at home or in small groups. The goal is simple: less time marking, more time helping kids understand.

RedMarker is for drill-style maths worksheets, initially for children aged 4 10: scan worksheet pages, see what s correct, spot what needs a second look, and keep work organised by student and class.

Red Marker - Get your evenings back from checking maths homework

Worksheet marking doesn't scale. RedMarker fixes that. Point your phone at a pile of maths worksheets to quickly get marked results. Built for ages 4–10, designed for the people doing the actual marking — parents, tutors, and teachers. Smart Scan moves you through multi-page booklets swiftly. Progress views show accuracy over time so you know exactly where to focus next. Less red pen. More teaching. Free tier refreshes monthly. Buy credits if you need more — no subscription.
