# PASS by U+ vs 카카오페이

The clearest difference is rating: 카카오페이 at 4.2 against PASS by U+'s 1.6. 카카오페이 also leads on update cadence (weekly vs monthly) and ratings volume (132 vs 7). PASS by U+'s advantage is in-app purchases (none vs 26) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. 카카오페이 sells 26 one-off in-app purchases. PASS by U+ asks for nothing beyond the download.

카카오페이 holds the better App Store score, 4.2 against 1.6. That said, the two scores are not equally well evidenced: 카카오페이 has 132 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 73% of PASS by U+'s written reviews are positive against 49% of 카카오페이's, so the app with the better star average is not the one people write more warmly about.

PASS by U+ ships an update monthly, 카카오페이 weekly. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
