Verdict

The call

The clearest difference is ads: Azul at none against United Airlines's shown. Azul also leads on monetization model (free vs free with in-app purchases) and iOS requirement (16.0 vs 18.0). United Airlines's advantage is ratings volume (8.4M vs 16K) and update cadence (weekly vs every 3 weeks). On price, rating and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.8 for United Airlines against 4.8 for Azul. That said, the two scores are not equally well evidenced: United Airlines has 8.4M ratings behind it against 16K, so its average is the more settled of the two. Written reviews are what separate them: 41% of United Airlines's written reviews are positive against 30% of Azul's.

UpkeepUpdate frequency

United Airlines ships an update weekly, Azul every 3 weeks. Both last shipped on November 1, 2026.
