Twi is spoken by about 10 million people. Counted as Akan, which includes Fante; Twi proper is roughly two thirds of it.
On our measured language map, its closest relatives are Fulani, Kosmospik Weyo and Nusipe. If you speak one of those, much of the vocabulary will feel familiar from day one.
Every lesson is built from 2,000 real Twi sentences, aligned with their translations word by word and piece by piece, so you always see how the sentence actually works instead of memorizing flashcards. The grammar is discovered from the sentences themselves, 1,272 patterns so far, and a spaced-repetition quiz teaches it in the order that unlocks the most of the language first. Our measured estimate for reaching conversational level from English is about 1,175 hours of study. Read how it works.
Most apps only teach Twi through English, if they teach it at all. These starting languages already have a built course, and any other published language can be paired on request:
Speaker figures follow Ethnologue and national censuses, rounded. The difficulty estimate is calibrated against U.S. Foreign Service Institute data.
