Every screen below is the real Lockin app, scrubbing as you scroll. Eight scenes. Eight reasons students stick with it.

01 Sign in
Built for students

Create your free account in seconds. No credit card. No nonsense. Pick your courses and start revising the moment you land.

Free to start

Your revision, your rules.

Lockin syncs across web, iOS and Android. Whatever device you study on, your progress follows you.

Every exam board, every subject

The most complete UK
revision library on the planet.

AQA, Edexcel, OCR, WJEC, CCEA. Foundation or Higher. AS or A2. Pick your exact spec — we've got the rest.

02 Choose your course
All major boards

Every major exam board.

AQA, Edexcel, OCR, WJEC, CCEA — if it's on your spec, it's in Lockin. No more piecing together resources from five different sites.

Right tier, right content

Foundation & Higher tiers.

GCSE Maths Higher? Triple Science Foundation? We separate content by tier so you study exactly what your paper covers — nothing more, nothing less.

Instant setup

Seconds to get started.

Pick your subject and year group. Your personalised revision hub is ready immediately — no onboarding, no friction.

Understand exactly where you stand

Analytics that actually
tell you something.

Mastery scores, accuracy trends, EMA-tracked recent form, and a heatmap of every session you've ever done. The data finally serves you.

03 Inside a subject
Your subject hub

Everything for one subject.

Notes, questions, flashcards and past papers — organised by your exact spec. One tap into any topic. Zero hunting.

Mastery score

Know your weaknesses.

Mastery combines accuracy, syllabus coverage and confidence into a single per-topic score. The number that actually matters.

Current form

Are you actually improving?

An EMA tracks your most recent sessions so a few good days don't mask a downward trend — and a few bad days don't bury weeks of progress.

Daily breakdown

Every session recorded.

A heatmap calendar shows your study history at a glance. See exactly when you worked, how well you did, and where to push next.

Written from the specification

Notes that cover
everything.

Not copied from a textbook. Generated from your exact syllabus so nothing is missed and nothing is irrelevant.

04 Notes
Specification-accurate

Every topic. Zero gaps.

Every chapter in your syllabus has clear, structured notes. Read before you revise — and stop being surprised in the exam.

Organised by paper

Paper 1, Paper 2, Paper 3.

Content is split by exam paper so you know exactly what to revise for each sitting. No more cramming Paper 2 content the night before Paper 1.

Downloadable on Super

Save. Print. Study offline.

Lockin Super lets you download and print every set of notes. Perfect for the final exam-week sprint and the train ride to school.

Active recall that works

Stop reading.
Start remembering.

Passive revision doesn't stick. Questions and flashcards force your brain to retrieve information — the only way you actually learn it.

05 Practice
Exam-style questions

Real exam formats.

Multiple-choice questions modelled on past exam style. Immediate feedback, full explanations, and the right answer when you need it.

Smart selection

Lockin finds your weak spots.

Our PPS algorithm analyses your history and serves the topics you struggle with more often. No more revising what you already know.

Flashcards

Flip. Think. Remember.

Classic flip-card interface for rapid active recall. Self-assess after each card and the algorithm adapts to what you find hard.

Free or unlimited

40 free a day. Unlimited on Pro.

Free users get 40 questions and flashcards per day — enough to build a habit. Lockin Pro removes the cap entirely for revision sprints.

The final exam prep

Every past paper.
Sorted, instantly.

Stop hunting through PDFs scattered across the internet. Every paper, every mark scheme — categorised by board, year and tier.

06 Past papers
Real exam conditions

Practice like it's the real thing.

Real past papers and mark schemes, organised by exam board, year, and paper type. Everything you need to simulate the actual exam.

Sorted by year & paper

Paper 1, Paper 2, Higher, Foundation.

No more trawling Google. Every paper is categorised so you can jump straight to AQA Biology Paper 2 Higher 2024 without thinking.

The exam routine

Learn → Practise → Paper.

Use notes to learn the spec. Use questions to practise recall. Use past papers to confirm you're exam-ready. The full pipeline in one app.

Compete. Climb. Win.

Revision becomes
a competition.

Top students get featured. Rankings reset weekly. The drive to climb keeps you opening the app, day after day.

07 Leaderboard
Global rankings

See where you rank.

Compete against students across the whole platform. Every XP earned in study sessions pushes you higher up the board.

Course leaderboards

Your subject. Your rivals.

Each course has its own leaderboard. See who's actually top in AQA Biology or Edexcel Maths — not just top overall.

The podium

Top 3 get the spotlight.

The top three students sit on a winner's podium with custom avatars. Something genuinely worth competing for — and worth showing off.

Consistency beats cramming

Build the habit.
Keep the streak.

Every day you revise, your streak grows. Miss a day? 14 Streak Freezes protect you all year — because life happens.

08 Streaks
Daily streaks

Show up every day.

Your streak counter tracks consecutive days of studying. The longer it grows, the harder it is to stop. That's the whole point.

XP system

Earn for every correct answer.

XP is awarded for every right answer. It fuels your leaderboard position and gives you something visible to show for the work.

Streak Freezes

14 free passes per year.

Life gets in the way. Lockin gives you 14 Streak Freezes automatically — so one bad day doesn't wipe out weeks of consistent work.
