ReceptionRating · Positive reviews · Number of ratings

Payline Mobile holds the better App Store score, 3.3 against 2.1. That said, the two scores are not equally well evidenced: Stax Pay has 27 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 36% of Stax Pay's written reviews are positive against 33% of Payline Mobile's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Stax Pay ships an update monthly, Payline Mobile every 7 months. The most recent releases landed on October 29, 2026 and October 26, 2026 respectively.
