OtoOi Reader is a Korean reading app with something new every day. Read real-life Korean the way it is written — online forum posts with their comment threads, short travel stories, and news written from the facts — sentence by sentence, with audio for every sentence. ■ What you can read • K-Drama Next Door — short dramas written in the style of Korean online forums: advice posts and real-life stories, comments and all. After the ending, the author explains the twist and the everyday life behind it. A new episode every day. • Kai's Train Trips — Kai rides the KTX to cities around Korea and discovers the local food. 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. Older pieces: the Korean text and audio are free; the translations, word meanings and explanations are part of OtoOi Reader Pro, along with all TOPIK levels in Words. 7-day free trial. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless it is turned off at least 24 hours before the end of the current period.

Verdict
The clearest difference is ads: OtoOi Reader at none against 早く学ぶ韓国語's shown. OtoOi Reader also leads on update cadence (every 3 days vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
