How it works

A few minutes a day, in an order that makes words stay.

  1. 1

    Start where you are

    A 5-minute placement test estimates how many words you already know. Lemmi skips what you know and starts with what you need.

  2. 2

    A plan that fits your day

    Choose 5, 10, 20 or 30 minutes a day. Missed a few days? Lemmi spreads the catch-up so it never feels overwhelming.

    Reviews at the right moment

    Each word comes back right before you would forget it. Lemmi judges from your answers how well you know it, so there is nothing to rate.

Practice that sticks

Every word goes from “I have seen it” to “I can use it”.

Recognise, recall, use

Not just flashcards: choose the meaning, match pairs, fill the gap in a sentence and write the word from memory.

Type it, don’t just tap it

Honest feedback: small typos are marked, not punished. You see exactly which letters went wrong.

Hear it in UK or US English

Listening and dictation with UK or US pronunciation. Example sentences show every word in real context.

See your vocabulary grow

Your estimated level and how many words you recognise and can use. Progress by level and topic, an activity calendar, achievements and a daily streak with freezes.

Questions

Is Lemmi really free?

Yes. All 5000 words, the level test, every exercise and smart reviews are free, with no ads. Lemmi Pro is an optional subscription for those who want more.

What is Lemmi Pro?

An optional subscription in the iOS and Android apps: word collections beyond the 5000 (phrasal verbs, prepositions, prepositional phrases, idioms, English for business, IT and medicine), practice with typing or listening only, a prepositions trainer and detailed statistics with an export for Anki. It works on the web too with the same account, and you can cancel any time in your store settings.

What level is it for?

From beginner (A1) to advanced (C1). The placement test finds your level, so you don’t spend time on words you already know.

Does it work without the internet?

Yes. Lessons work offline; when you sign in, your progress syncs between your devices.

Do I need an account?

No, you can start right away. An account keeps your progress safe and syncs it between devices.

Where do the words come from?

From open research word lists: NGSL, NAWL and CEFR-J. Sources and licences.

How do I delete my data?

In the app: Settings → Privacy. Without the app: delete an account.
