See it in action

Straight to today's plan.

No loading screens that go nowhere. Open Kraemon and your dashboard is already built — next exam, streak, and today's playlist, ready to go.

How it works

Three steps. One revision plan.

Kraemon does the planning — you just do the revision.

1

Pick your subjects

Choose every GCSE subject you're sitting. Kraemon maps them to your actual exam board spec — AQA, Edexcel, OCR, Eduqas, WJEC, or CCEA — and imports every topic automatically.

2

Do the session

Kraemon builds a daily topic playlist, sized to suit you and the moment. After each topic, you rate your recall — very little, the main points, or all of it. That one honest tap is all the data the algorithm needs to schedule your next review.

3

Watch your coverage grow

The syllabus coverage screen shows exactly which topics are mastered, which need work, and which haven't been touched. As exams approach, focus automatically shifts to what matters most.

Everything you need

Built for GCSE, start to finish.

Every feature in Kraemon connects back to one goal: getting more marks in your actual exams.

🧠

Smart Scheduling

The open-source FSRS-5 algorithm — benchmarked on hundreds of millions of real reviews — calculates the exact moment your memory needs reinforcing. You never waste time revising what you already know.

+ Themes & personalisation

For students

Stop guessing what to revise.

Every morning, Kraemon builds your personal revision playlist — shaped by what you know, what you're shaky on, and how close each exam is. You just open the app and start.

  • ✓No planning needed. Your daily queue is built automatically from your actual exam schedule.
  • ✓Honest progress. The coverage screen shows real mastery — not just topics you've clicked on once.
  • ✓Exam crunch handled. When you're two weeks from a paper, Kraemon automatically prioritises that subject.
  • ✓Sessions that suit you. Each one timed for you and the day you have — so it fits around school, sports, and everything else.
Kraemon active recall session Kraemon subject health overview

For parents

Evidence-based revision, mapped to the spec.

Kraemon uses the same spaced-repetition science medical students rely on for some of the hardest exams in the world. No gaming mechanics, no social feeds — just focused, effective revision.

  • ✓Mapped to their actual papers. 139 subjects across all six GCSE boards — AQA, Edexcel, OCR, Eduqas, WJEC, and CCEA. Every topic is exactly what's on the spec.
  • ✓No adverts. Ever. Kraemon will always be completely free for students and completely ad-free. No subscriptions, no upsells.
  • ✓No social features. There's nothing to scroll, no comments, no followers. Just revision.
  • ✓Transparent progress. The subject health scores show exactly where your child is strong and where they need more time — before it's too late to act.

For teachers

The revision tool you'd actually recommend.

Kraemon is built on the learning science you already know — spaced repetition, interleaving, retrieval practice. It just makes all of that automatic for students who wouldn't do it themselves.

  • ✓Spec-accurate content. Every subject is mapped to a real exam board spec. Students can't accidentally revise the wrong curriculum.
  • ✓Automatic interleaving. Kraemon mixes topics across subjects every session — students don't just block-revise Chemistry then forget it.
  • ✓Closes the planning gap. Most students don't revise effectively because they don't know what to revise. Kraemon solves that problem entirely.
  • ✓Habit-forming. Daily streaks and short sessions build a consistent revision habit — not a last-minute panic.

Learning science inside

Spaced repetition

FSRS-5 algorithm schedules each review at precisely the right moment to prevent forgetting.

Interleaved practice

Sessions mix topics from different subjects — proven to improve long-term retention.

Retrieval practice

Each session ends with a recall rating — forcing retrieval, not passive re-reading.

For parents and teachers

How revision actually works, once a month.

Sixteen years of teaching it, and the research behind it — spacing, retrieval practice, why re-reading feels productive and isn't, and what genuinely helps at home in the run-up to exams. Practical, short, and never a sales pitch.

Why Kraemon exists

I taught kids how to revise for 16 years. Then they went home.

I spent sixteen years teaching science in Leeds and Bradford. Revision technique gets taught in every school — how to plan it, how to space it, how to test yourself rather than re-read. It's also abstract, hard to get your head around, and the first thing to be neglected once a student is working alone.

Home is where almost all revision actually happens, and it was the one place I could never reach. Kids don't fail at revision because they're lazy — they fail because the hard thing that works doesn't feel like it's working, and the easy thing that doesn't work feels great.

Kraemon is my answer to that. Not another revision app — a scheduling tool and a procrastination unblocker. Your teachers have already given you the resources. It tells you what to work on, when, and coaches you through actually doing it.
