# NUMEN vs 성인의 수학

The clearest difference is ads: NUMEN at none against 성인의 수학's shown. 성인의 수학's advantage is update cadence (weekly vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. NUMEN sells 1 one-off in-app purchase and 성인의 수학 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

NUMEN ships an update every 5 weeks, 성인의 수학 weekly. Both last shipped on October 31, 2026.
