About this app
Four ways to get better at English — a daily feed, deep vocabulary lessons, spoken role-plays, and a CEFR test simulation that shows where you stand.
Find your level, then watch it move
An adaptive CEFR test simulation estimates your level, from A1 to C2. It is practice, not an official certification. From then on you see it charted over time, with practice sets at every band to keep the next level in reach.
A daily feed worth scrolling
There is always something ready to learn: new words with pictures, audio and real example sentences, mixed with quick questions to keep you honest. Filter it down to the levels you care about.
Vocabulary that goes deep
Every word arrives complete — meaning, IPA, audio, examples, synonyms and antonyms, common collocations and its word family. Save the ones you want, group them into your own lists, and let spaced repetition bring them back exactly when you are about to forget them.
Lessons on a clear path
Short lessons grouped into units: meet each new word, then practise it straight away. The trail unlocks as you go, so you always know what comes next.
Speak out loud, without the nerves
Role-play real situations — ordering in a café, joining a meeting, asking for directions. Hear the setup, take a moment to plan, then say your answer aloud. Your speech is transcribed on your device, and our AI reads what you said: it checks you covered the task, even when you paraphrased, and suggests better wording by quoting your own sentences back to you.
It corrects your words, not your accent. The AI never receives your audio and never judges how you sound. Retakes are unlimited, and nobody is listening.
Progress, honestly measured
Three separate CEFR tracks — placement, vocabulary and speaking — because they genuinely move at different speeds, and one number would hide that. Alongside them: your streak, XP, words mastered and recent activity.
Start without an account
Your progress is saved from the first launch, no sign-up required. Add an email or Google account later if you want it on a second device.
