Travel notes with the facts and sources. • News — Korean news written from the facts, in an Easy and a Standard version. • Story — Kai's everyday life in Korea, told in short conversations (beginner level). ■ How it helps you read • Read first, then check: open the English translation one sentence at a time. • Tap a word for its meaning in that sentence, its dictionary form and how it is conjugated. • Tap an underlined grammar pattern for a short explanation of how it works in that sentence. • Audio for every sentence. • A TOPIK level for every piece, so you can find what fits you. ■ Words — see your Korean grow • Mark words and grammar as Known, Learning or Not yet while you read. • See how many TOPIK level 1–6 words and grammar patterns you know, level by level. • Your known-word rate on every piece shows what you can read next. ■ Subscription New pieces are free for 7 days after they come out.
