ReceptionRating · Positive reviews · Number of ratings

PortSIP UC holds the better App Store score, 4.1 against 2.7. That said, the two scores are not equally well evidenced: PortSIP UC has 93 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 35% of Linphone's written reviews are positive against 32% of PortSIP UC's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Linphone ships an update every 2 months, PortSIP UC every 2 weeks. The most recent releases landed on November 6, 2026 and November 10, 2026 respectively.
