# PASS by SKT vs PASS by U+

The clearest difference is rating: PASS by SKT at 2.6 against PASS by U+'s 2.0. PASS by SKT also leads on ads (none vs shown) and ratings volume (87 vs 8). PASS by U+'s advantage is review sentiment (73% vs 65%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

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

PASS by SKT holds the better App Store score, 2.6 against 2.0. That said, the two scores are not equally well evidenced: PASS by SKT has 87 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 65% of PASS by SKT's written reviews are positive against 73% of PASS by U+'s, so the app with the better star average is not the one people write more warmly about.
