Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

교보증권 Win.K holds the better App Store score, 3.7 against 1.3. That said, the two scores are not equally well evidenced: 바이오인증공동앱 has 32 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 34% of 바이오인증공동앱's written reviews are positive against 31% of 교보증권 Win.K's, so the app with the better star average is not the one people write more warmly about.
