Verdict
The clearest difference is rating: Payline Mobile at 3.3 against Stax Pay's 2.1. Payline Mobile also leads on iOS requirement (9.0 vs 17.6). Stax Pay's advantage is update cadence (monthly vs every 7 months) and ratings volume (27 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.

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