Content

Word lists are easy.
Knowing what to learn next isn't.

CoLingua ships structured courses from greetings to real conversation, plus wordbooks tied to the exams people actually sit.

📚

Graded wordbooks

CET-4, CET-6, TOEFL, IELTS, GRE, Gaokao and Kaoyan for English, plus core vocabulary sets for every other language.

🧭

Structured courses

Units and lessons that build in order — greetings, introductions, daily life — each entry with IPA and a native-style pronunciation.

🎯

Daily content

A short piece of real material each day, matched to your level, so practice becomes a habit rather than a project.

🤖

AI tutor

Ask anything in the target language. The tutor answers, then explains the mistake you just made — hints first, answers second.

🎙

Pronunciation feedback

Speak a word or a sentence and get scored on individual sounds, not just “try again”.

✍️

Writing & grammar

Write a paragraph, get corrections with reasons, and a short report on what to work on next.

Design

Calm by default,
quietly demanding.

Most language apps are optimised for daily active users. CoLingua is optimised for the day you stop needing it.

Guilt-free streaks. Miss a day and nothing breaks, shames you, or starts charging you.
Start without an account. Guest mode gets you into a course immediately; sign in only when you want to sync.
Your progress is yours. Export or delete everything from the app; accounts can be removed in one tap.
No ads inside lessons. A learning session should not be interrupted by a video.

Pick a language. Start with ten words.

Download the Android build, choose a wordbook, and let the daily content do the nagging.
