Red Marker
Get your evenings back from checking maths homework
What it does
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.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
