ReceptionRating · Positive reviews · Number of ratings

Rapaport Trade (RapNet) holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Rapaport Trade (RapNet) has 331 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 62% of Rapaport Trade (RapNet)'s written reviews are positive against 78% of hk.co's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency
