# SentenceDeck vs Learn Korean

The clearest difference is ads: SentenceDeck at none against Learn Korean's shown. Learn Korean's advantage is update cadence (every 3 weeks vs every 6 weeks) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SentenceDeck sells 3 one-off in-app purchases and Learn Korean sells 2 in-app purchases, starting at $1.00 per month. Whichever you choose, the download price is not the number that matters.

SentenceDeck ships an update every 6 weeks, Learn Korean every 3 weeks. Both last shipped on October 31, 2026.
