ReceptionRating · Positive reviews · Number of ratings

ContactsPro HX holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: SessionTalk Pro Softphone has 30 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 62% of SessionTalk Pro Softphone's written reviews are positive against 22% of ContactsPro HX's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SessionTalk Pro Softphone ships an update every 3 days, ContactsPro HX every 6 weeks. Both last shipped on November 1, 2026.
