Four exams, one method — and everything missing elsewhere: a path adaptive to your level, microphone-scored pronunciation, spaced repetition and official-format mock exams. You pick your certificate, Blue takes you to the target score, without losing your evenings.
Most candidates churn through past papers with no method, redo what they already know… and stall. The problem isn't your level: it's the lack of direction.
Hundreds of exercises, no priority. You work at random, often on what you already master.
Without a diagnosis, you can't target what really costs you points on exam day.
A big cram the night before is no substitute for regular training — and it shows in the result.
Tight timing, multiple sections, recurring traps specific to each exam: discovering them on the day is already too late.
Where other apps line up past papers in bulk, Blue brings the whole exam together, tells you what to review and when, and moves you forward on what really matters. One app, from diagnosis to exam day.
The placement test targets your weak spots; Blue builds a tailored daily program, adapted to the exam you're aiming for. No more random work.
Conversations, monologues, academic lectures depending on your exam. Native audio, adjustable speed, varied accents.
Sentence and text gap-fills, passage comprehension, information spotting — in your exam's format.
Guided Speaking and Writing prompts, with grading criteria and model answers — for TOEFL, IELTS and Cambridge in particular.
The full exam, timed, in real conditions, followed by a detailed review of your weaknesses.
Install Blue as an app (PWA) and make progress on the train, distraction-free. Everything is synced.
A clear dashboard: estimated CEFR level, weak spots and progress curve. You always know what to work on first.
Every answer is detailed: you understand your mistake, learn the rule and never repeat it.
Not a bulk collection of past papers: structured content, designed to win points, that grows regularly.
Features designed for long-term memory and exam-day confidence — not just exercises to grind through.
Your placement test drives everything: lessons unlock by your CEFR level and the daily plan targets your weak spots first.
Record yourself: Blue compares your reading to the model, scores you and colour-highlights the words to work on.
Words and your mistakes come back at the right time, just before you forget — the method that makes it stick (SRS).
Quiz, dictation, matching, flashcards: the same word worked from every angle, recognition and production alike.
Real dialogues — café, interview, doctor, meeting — to practise living English, not just multiple-choice.
A live estimate of your exam-day score, refined with practice, pointing to your top lever.
