ReceptionRating · Positive reviews · Number of ratings

iPECS UCS 6+ holds the better App Store score, 5.0 against 2.6. That said, the two scores are not equally well evidenced: 3CX has 321 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 28% of 3CX's written reviews are positive against 22% of iPECS UCS 6+'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

3CX ships an update monthly, iPECS UCS 6+ every 2 months. The most recent releases landed on October 16, 2026 and October 5, 2026 respectively.
