RedMarker — Get your evenings back from checking maths homework

by

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.

It’s live on iPhone and Android. I’d love your feedback: what would make this indispensable for your workflow—homework, tuition, or the classroom?

Smart idea! Saving evenings from homework drudgery is a game-changer for parents and tutors. I'll give it a spin on my phone. If you're up for it, I'm launching The Sponge on PH soon...an AI-powered flashcard app with a browser extension that turns webpages into spaced repetition study cards. Would appreciate a follow (PRODUCT HUNT LAUNCH link in my profile).

@rianbrob Hello Rian, yours sounds like a very useful app. Have followed you and I'm looking forward to demo-ing yours after launch. Whilst I'm a long time techie, I'm such a rookie in app marketing space, but learning plenty every day. I wish you the best of luck with the launch.
