# Math puzzles vs 단어채집

The clearest difference is in-app purchases: 단어채집 at none against Math puzzles's 1. 단어채집 also leads on ads (none vs shown) and update cadence (every 2 days vs every 9 months). Math puzzles's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price there is nothing between them.

Both are free to download. Math puzzles sells 1 one-off in-app purchase. 단어채집 asks for nothing beyond the download.

Math puzzles ships an update every 9 months, 단어채집 every 2 days. The most recent releases landed on November 2, 2026 and October 31, 2026 respectively.
